O It disappears at it moves through the crust.
OIt spreads out in random directions.
OIt radiates outward in all directions.
OIt increases as it reaches the surface.

Answers

Answer 1

What happens to the energy produced by blocks of Earth's crust slipping past each other is it radiates outward in all directions. (Option C).

What happens to the energy?

When blocks of the Earth's crust slip past each other during an earthquake, the energy that is released does not disappear, spread out randomly, or increase as it reaches the surface.

Instead, the energy radiates outward in the form of seismic waves. These seismic waves travel through the Earth in all directions from the point of the earthquake's origin causing the ground to shake.

The energy carried by these waves is what is felt as the shaking during an earthquake and can be detected and measured by seismometers.

Thus, what happens to the energy produced by blocks of Earth's crust slipping past each other is it radiates outward in all directions.

Given the balanced equation: 3 H2 + N2 2 NH3 ,
how many moles of NH3 will be produced if 50.8 g N2
reacts with 187.3 g H2?

Answers

Taking into account the reaction stoichiometry, 3.63 moles of NH₃ will be produced if 50.8 g N₂ reacts with 187.3 g H₂.

Reaction stoichiometry

In first place, the balanced reaction is:

3 H₂ + N₂ → 2 NH₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

H₂: 3 molesN₂: 1 mole NH₃: 2 moles

The molar mass of the compounds is:

H₂: 2 g/moleN₂: 28 g/moleNH₃: 31 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

H₂: 3 moles ×2 g/mole= 6 gramsN₂: 1 mole ×28 g/mole= 28 gramsNH₃: 2 moles ×31 g/mole= 62 grams

Limiting reagent

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

Limiting reagent in this case

To determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 6 grams of H₂ reacts with 28 grams of N₂, 187.3 grams of H₂ reacts with how much mass of N₂?

[tex]mass of N_{2} =\frac{187.3 grams of H_{2} x28 grams of N_{2}}{6 grams of H_{2}}[/tex]

mass of N₂= 874.067 grams

But 875.087 grams of N₂ are not available, 50.8 grams are available. Since you have less mass than you need to react with 187.3 grams of H₂, N₂ will be the limiting reagent.

Mass of NH₃ formed

Considering the limiting reagent, the following rule of three can be applied: if by reaction stoichiometry 28 grams of N₂ form 2 moles of NH₃, 50.8 grams of N₂ form how many moles of NH₃?

[tex]moles of NH_{3} =\frac{50.8 grams of N_{2} x2 moles of NH_{3} }{28 grams of N_{2}}[/tex]

moles of NH₃= 3.63 moles

Finally, 3.63 moles of NH₃ will be produced if 50.8 g N₂ reacts with 187.3 g H₂.

What classifies a substance as an element?

What classifies a substance as a compound?

Answers

An element is a substance that cannot be broken down by chemical means. Elements are extremely particular compounds that serve as the foundation for all life and matter (well other than the stuff smaller than atoms). It can contain one atom or trillions of them for anything to be an element, however atoms of different types cannot be combined in. That is to say, every atom has a set number of protons, ranging from 1 to 118. You can be positive that the substance you have is hydrogen if there is just one proton present. Mercury is what you get if you have 80 protons. Atoms of pure hydrogen only contain one proton. As most people are aware, if you add oxygen to it, it turns into water, which is no longer an element but a compound. Nevertheless, the building blocks are the elements. Every single object you can see is composed of elements, whether there are many of them, as there are in the human body, or only a few, as there are in salt.

A compound is a substance with a definite composition (with some leeway there, there are 'non-stoichiometric' compounds), that is composed of 2 or more elements.

Further explanation:

A compound in chemistry is a material that is created by mixing two or more distinct chemical elements in such a way that the atoms of the various elements are kept together by strong chemical bonds. These bonds form as a result of the sharing or exchange of electron s among the atoms. A molecule is the smallest, unbreakable unit of a substance.

A mixture is not a compound since there is no bonding between the atoms of the constituent substances in a mixture. In certain cases, mixing dissimilar elements causes chemical reactions that result in the formation of bonds between the atoms and the molecules of a compound. Other possibilities allow mixing distinct components without causing a reaction, preserving the separate identities of the elements. When elements are combined, reactions can happen quickly or slowly (for example, when iron is exposed to oxygen) (as when lithium is exposed to oxygen). There are times when an element is introduced to a chemical, a reaction takes place, creating new compounds (as when pure elemental sodium is immersed in liquid water).

A compound frequently looks and acts quite different from any of the constituent parts. Think about hydrogen (H) and oxygen, for instance (O). At standard atmospheric pressure and room temperature, both of these substances are gases. However, they combine to form the well-known material known as water, which is a liquid at room temperature and at normal atmospheric pressure and whose molecules each contain two hydrogen atoms and one oxygen atom (H2O).

Few elements' atoms readily combine with those of other elements to produce compounds. These gases—helium, neon, argon, krypton, xenon, and radon—are referred to as noble or inert gases. Compounds made of certain elements can be formed easily with other elements. Examples include fluorine, chlorine, and oxygen.

2) The adjective compound refers to something that is made up of several different components. Examples of this usage include compound eyes, which are found in a variety of insects, compound microscopes, which are high-power magnifying devices made up of multiple lenses, compound sentences, which are organized collections of smaller sentences that form a single integrated perceptual environment, and compound documents.

What are molecules?

The slightest particle of importance contains all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms.

If they include more than one atom, the particles can be the same (an oxygen molecule has two oxygen atoms) or additional (a wetness molecule contains two hydrogen particles and one oxygen atom). Natural molecules, such as proteins and DNA, can be created up of many thousands of atoms.Particles are the introductory unit of an element. They consist of a nucleus and cover electrons. When an atom has an insufficient electron shell, it is said to have valence electrons. When two or more additional atoms come concurrently to share outer surface valence electrons, a chemical (covalent) bond is formed, and they join a lower power state. When atoms bond, significance is released in an exothermic response. If the covalent bond is broken and the molecule is split separated, it needs energy information and is thereby endothermic.

Question 9
What pressure will be exerted by 15 g of carbon dioxide gas in a 20 L container at 0 °C?

Answers

Answer:

0.382 atm

Explanation:

In order to find the pressure, you need to know the moles of carbon dioxide (CO₂) gas. This can be found by multiplying the mass (g) by the molar mass (g/mol) of CO₂. It is important to arrange the conversion in a way that allows for the cancellation of units.

Molar Mass (CO₂): 12.011 g/mol + 2(15.998 g/mol)

Molar Mass (CO₂): 44.007 g/mol

15 grams CO₂               1 mole
----------------------  x  ------------------------  =  0.341 moles CO₂
                                44.007 grams

To find the pressure, you need to use the Ideal Gas Law equation.

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = Ideal Gas Constant (0.08206 atm*L/mol*K)

-----> T = temperature (K)

After you convert Celsius to Kelvin, you can plug the given and calculated values into the equation and simplify to find the pressure.

P = ? atm                              R = 0.08206 atm*L/mol*K

V = 20 L                               T = 0 °C + 273.15 = 273.15 K

n = 0.341 moles

PV = nRT

P(20 L) = (0.341 moles)(0.08206 atm*L/mol*K)(273.15 K)

P(20 L) = 7.64016

P = 0.382 atm

Radioactive decay occurs when unstable isotopes have their nuclei ruptured due to atomic instability. To understand why an isotope disintegrates, we need to look at the atomic nucleus. It is known that the nucleus is loaded with positive particles (protons), and that these are very close to each other. It is also true that particles with equal charges repel each other. Therefore, the proximity of the protons causes them to start to repel each other, in an attempt to take up as much space as possible. In view of this, the nucleus breaks, as it cannot bear these repellent charges.

What is the molar mass of an unknown gas
with a density of 4.95 g/L at 1.00 atm and
25.0 °C?

Answers

Answer:

121 g/mol

Explanation:

To find the molar mass, you first need to calculate the number of moles. For this, you need to use the Ideal Gas Law. The equation looks like this:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = constant (0.0821 L*atm/mol*K)

-----> T = temperature (K)

Because density is comparing the mass per 1 liter, I am assuming that the system has a volume of 1 L. Before you can plug the given values into the equation, you first need to convert Celsius to Kelvin.

P = 1.00 atm                         R = 0.0821 L*atm/mol*K

V = 1.00 L                             T = 25.0. °C + 273.15 = 298.15 K

n = ? moles

PV = nRT

(1.00 atm)(1.00L) = n(0.0821 L*atm/mol*K)(298.15 K)

1.00 = n(0.0821 L*atm/mol*K)(298.15 K)

1.00 = (24.478115)n

0.0409 = n

Now, we need to find the molar mass using the number of moles per liter (calculated) and the density.

0.0409 moles           ? grams           4.95 grams
----------------------  x  ------------------  =   ------------------

Molar mass of citric acid (C6H8O7) =  12×6 + 1.008×8 + 16×7

                                                           =  192.064 g/mol

Current, I = 67 A

Time, t = 14 h = (14×60×60) s

Now total Charge passed , Q = I t = 67×14×60×60 = 3376800 C

moles of electrons passed = [tex]\frac{Q}{96500}[/tex][tex]=\frac{3376800}{96500}=34.992[/tex] mole  e⁻

531.2 grams of oxygen and 608.22 grams of C6H12O6 make up the potential yield.

What is a Moles?A mole is the amount of a substance that contains precisely 6.02214076 X 1023 of the substance's fundamental components.If a material has the same mass as 12.000 g of 12C and the same number of elementary particles as atoms, it is said to have a mole of that substance.The mole can be used to determine the simplest compound formula and calculate the quantities needed for chemical reactions. Molarity, a related concept, comes in handy when discussing reactions in solutions. Molarity is the measure of how many moles of a solute are present per liter of a solution (M).Molecular quantities are those that cannot be measured in terms of grams or milligrams. This way, a mole counts the number of atoms, ions, or molecules.

Determine the reaction's theoretical yield:

Given is the reaction: 6 CO2 + 6 H2O = C6H12O6 + 6 O2.

2.38 x 102 g of H2O are provided as the mass.

Given is 18.6 moles of CO2.

6 CO2 + 6 H2O →  C6H12O6 + 6 O2

6 moles of H2O  1 mole of C6H12O6

1 mole of water equals 0.6 moles of C6H12O6.

18gm of H2O = 276/6 gm of C6H12O6

2.38*10^2 gm of H2O = ? gm of C6H12O6

[tex]=\frac{2.38*10^{2} *\frac{276}{6} }{18}[/tex]

[tex]=608.22gms[/tex] of C6H12O6

1 mole of  C6H12O6 = 276gms

? moles of C6H12O6 = 608.22gms

= 608.22/276

= 2.2 moles of C6H12O6

6 moles of CO2 = 6 moles of O2

1 mole of CO2 = 1 mole of O2

∴ 18.6 moles of CO2 = 18.6 moles of O2

1 mole of O2 = 32gms of O2

∴18.6 moles of O2 = ?  gm

= 18.6*32

= 531.2gms of O2

Hence 531.2 grams of oxygen and 608.22 grams of C6H12O6 make up the potential yield

State which substance is undergoing oxidation and which substance is undergoing reduction in the following reaction:

Mg (s) + H2SO4 (aq) ---> MgSO4 (aq) + H2 (g)

Answers

Answer:

Mg(s) = oxidized

H₂SO₄(aq) (hydrogen) = reduced

Explanation:

Oxidized substances lose electrons and see an increase in oxidation number. Reduced substances gain electrons and see a decrease in oxidation number.

Lone elements always have an oxidation number of 0. H₂SO₄ and MgSO₄ are ionic compounds that can be broken up into a cation and polyatomic anion. The anion, SO₄²⁻, has an overall oxidation number of -2. Therefore, to make the overall charge of the ionic compound neutral, the hydrogen in H₂SO₄ has an oxidation state of +1 (bc there are two hydrogens) and the magnesium in MgSO₄ has an oxidation state of +2.

Since Mg(s) is losing electrons (goes from 0 to +2), it is being oxidized. Since the hydrogen in H₂SO₄(aq) is gaining electrons (goes from +1 to 0), it is being reduced.

determine the pressure change when a gas at a constant volume at 7.0 atm is heated from 15°C to 70°C. Show your work​

Answers

Answer:

33 atm

Explanation:

If all other variables are held constant, you can use Gay-Lussac's Law to find the pressure change:

P₁ / T₁ = P₂ / T₂

In this equation, "P₁" and "T₁" represent the initial pressure and temperature. "P₂" and "T₂" represent the final pressure and temperature. You can plug the given values into the equation and simplify to find P₂.

P₁ = 7.0 atm                     P₂ = ? atm

T₁ = 15 °C                         T₂ = 70 °C

P₁ / T₁ = P₂ / T₂                                       <----- Gay-Lussac's Law

7.0 atm / 15 °C = P₂ / 70 °C                   <----- Insert values

0.46667 = P₂ / 70 °C                             <----- Simplify left side

33 = P₂                                                  <----- Multiply both sides by 70

A sample of flammable liquid is placed into an enclosed cylinder which is then fitted with a movable piston. Initially the cylinder maintains a volume of 1.7 L. The sample is ignited producing gas and releasing 439.6 J of energy. To what volume will the cylinder expand to if it must expand against a pressure of 738.52 mmHg. Assume all the energy released is converted to work used to push the piston? Answer to 1 decimal space.

Answers

Cylinder will expand to 6.08 Lit by assuming that all the energy released is converted to work used to push the piston.

Concept of work :If we  apply force on an object and if the object moves and changes it's position, then product of the force and the displacement of an object in the direction of applied force is called work.

Given,

Pressure= P= 738.52 mm Hg = 0.97 atm. (∵ 760 mm Hg = 1 atm)

Initial volume =V1= 1.7 L

Work done = W = 439.6 J

As we need our answer in litters ..

let's convert the work done into suitable units

∴work done = W = 4.26 L-atm (∵ 1 J = 101.3 L-atm)

As given all the energy is assumed to converted into work so we need not to worry About heat loss or entropy.

work done = pressure * difference in volume

W = PΔV

ΔV = 4.26÷ 0.97

∴ΔV = 4.38 LIt

There for, the volume expanded = 4.38 Lit

So, total volume = 4.38+ 1.7 = 6.08 Lit.

What is a technique for determining an unknown molaritry of acid by adding a base of know malarkey to a known volume of acid

Answers

Titration is a technique for determining unknown molarity of acid by adding a base of know malarkey to a known volume of acid

The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained " is the definition of titration. Titration, commonly referred to as titrimetry, is a method of chemical qualitative analysis used to determine the concentration of a certain analyte in a mixture.

The goal of titration is to identify the equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, which is a key analytical chemistry technique also known as volumetric analysis. The stoichiometry of the reactants determines how many reactants have been mixed at the equivalence point.
