Anyone Know How To Do This?

Answer 1

Answer:

3.26×10⁵ L

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 3.5×10⁵ L

Initial temperature (T₁) = 27 °C

Initial pressure (P₁) = 101 KPa

Final temperature (T₂) = –10 °C

Final pressure (P₂) = 95 KPa

Final volume (V₂) =?

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(ºC) + 273

Initial temperature (T₁) = 27 °C

Initial temperature (T₁) = 27 °C + 273

Initial temperature (T₁) = 300 K

Final temperature (T₂) = –10 °C

Final temperature (T₂) = –10 °C + 273

Final temperature (T₂) = 263 K

Finally, we shall determine the new volume of the tank. This can be obtained as follow:

Initial volume (V₁) = 3.5×10⁵ L

Initial temperature (T₁) = 300 K

Initial pressure (P₁) = 101 KPa

Final temperature (T₂) = 263 K

Final pressure (P₂) = 95 KPa

Final volume (V₂) =?

P₁V₁ / T₁ = P₂V₂ / T₂

101 × 3.5×10⁵ / 300 = 95 × V₂ / 263

117833.333 = 95 × V₂ / 263

Cross multiply

95 × V₂ = 117833.333 × 263

95 × V₂ = 30990166.6

Divide both side by 95

V₂ = 30990166.6 / 95

V₂ = 3.26×10⁵ L

Thus, the new volume of the tank is 3.26×10⁵ L

Which alkaline earth metal has the highest ionization energy? Refer to the periodic table.

calcium
magnesium
barium
strontium

Answers

I’m pretty sure the answer is Barium. I hope it helps.

The highest ionization energy of alkaline earth metal is calcium. Therefore, option (A) is correct.

What is the ionization energy?

The ionization energy can be described as the minimum energy that an electron has to absorb to come out of the effect of the nucleus of a gaseous atom or ion.

It tells about the reactivity of chemical compounds and determines the strength of chemical bonds. The units of ionization energy are electronvolts or kJ/mol.

Ionization energy measures the difficulty in removing an electron from an atom or ion and the loss of electron occurs in the ground state of the chemical species.

According to the general configuration of alkaline earth metals, they contain two electrons in their valence shell. The atomic size of alkaline earth metals increases as we move down the group. The electronegativity and effective nuclear charge of alkaline earth metals decrease.

The electron can easily be lost from the atom as we move down the group. Therefore, calcium present at the top of the group has the highest ionization energy.

Answer: 21.13 L of [tex]H_2O[/tex] will be produced from the reaction of 24.65 L of oxygen

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

[tex]2C_2H_6(g)+7O_2(g)\rightarrow 4CO_2(g)+6H_2O(g)[/tex]

i need this like rn please.

Answers

Answer:

0.347

Explanation:

Al is the limiting reagent.

Explanation:

The stoichiometry of the reaction is such that 4 moles of Al are required for every 3 moles of diatomic oxygen. This means that if the ratio of Al to diatomic oxygen is greater than 4/3, then the oxygen is the limiting reagent. If the ratio of Al to diatomic oxygen is less than 4/3, then Al is the limiting reagent.

The problem state that the ratio of Al to diatomic oxygen is

The ration of Al to diatomic oxygen is less than 4/3, so Al is the limiting reagent.

So it would take 0.347 moles of Al to completely react with all of the oxygen, however there is only 0.32 moles of Aluminum present, so there is not enough Al to react with all of the oxygen, and so we say that the Al is the limiting reagent.

The mass of Aluminum are needed to produce 21.6 grams of Aluminum oxide (Al₂O₃) is

What is mass?

Mass of any element is equal to the product of its number of moles and molar mass.

For the compound, Aluminum oxide (Al₂O₃)

The atomic masses of Aluminum is 23 and oxygen is 16.

Molecular or molar mass = ( 2 × 23 ) + ( 3 × 16 ) units

M = 46 + 48 = 94 units

The mass of Aluminum in 1 mole of aluminum oxide ,46 grams in 94 grams

Mass of Aluminum in the given 21.6 g of Aluminum oxide will be;

94 grams of Aluminum oxide contains 46 grams of Aluminum.

21.6 grams of Aluminum oxide will contain ( 46 / 94 ) × 21.6 = 10.57g of Aluminum.

Therefore, 10.57g of Aluminum are needed to produce 21.6 grams of Aluminum oxide (Al₂O₃)

You can fit 25 drops of substance X on a penny and 12 drops of substance Y on a different penny. Explain the difference in terms of strength of IMF.

Answers

Answer:

In the experiment performed involving the number of liquid drops that a penny can hold, 25 drops of substance X can fit in a penny while only 12 drops of substance Y can fit on another penny because, substance X is more viscous than substance Y. Thus, the intermolecular forces present in substance X are stronger than those present in substance Y.

Explanation:

Intermolecular forces (IMF) are the forces which exist between the neighboring molecules of a a substance. These forces, though weaker than intramolecular forces which acts between neighboring atoms, they still are responsible for several differences in the physical properties of substances with comparatively similar molecular masses.

The three major types of intermolecular forces are, hydrogen bonding, dipole–dipole interactions and  London dispersion forces.

The existence of intermolecular forces in molecules of substances results in increase in melting and boiling points, surface tension,  capillary action, viscosity, as well as surface area of substances,

Viscosity, which is the resistance to flow offered by a liquid increases with increase in the intermolecular forces between the molecules of a liquid.

In the experiment performed involving the number of liquid drops that a penny can hold, 25 drops of substance X can fit in a penny while only 12 drops of substance Y can fit on another penny because, substance X is more viscous than substance Y. Thus, the intermolecular forces present in substance X are stronger than those present in substance Y.

A student dissolves 13. g of stilbene (C14H12) in 100. mL of a solvent with a density of 0.85 g/mL. The student notices that the volume of the solvent does not change when the stilbene dissolves in it.
Calculate the molarity and molality of the student's solution. Be sure each of your answer entries has the correct number of significant digits.

Answers

Answer:

Molarity = 0.72M

Molality = 0.85M

Explanation:

Molarity and molality are two measures of molar concentration, and they can be calculated as follows:

Molarity = number of moles/volume of solvent

Molality = number of moles/mass (kg) of solvent

Mole = mass/molar mass

Molar mass of stilbene (C14H12) = 12(14) + 1(12)

= 168 + 12

= 180g/mol

mole of stilbene = 13/180

mole = 0.072mol

Volume = 100mL = 0.1L

molarity = 0.072/0.1

Molarity = 0.72M

Molality = number of moles ÷ mass (kg) of solvent

To get mass of solvent, we use;

Density = mass/volume

Mass = density × volume

Mass = 0.85g/mL × 100mL

Mass = 85g

Mass in kg = 85/1000 = 0.085kg

Molality = 0.072/0.085

Molality = 0.847M

Molality = 0.85M

Answers

Answer:

I have the lowest electronegativity of the nonreactive elements. My family name is alkali metals. I am classified as a reactive metal. I have one valence electrons.

Explanation:

Electronegativity refers to the ability of the atoms of an element to attract electrons to itself. Based on their nature, non-metals are electronegative elements whereas metal are electropositive as they have a tendency to give up their electrons rather than attract electrons to themselves.

In the periodic table of elements, non-metallic character, and hence, electronegativity increases from left to right across a period, and decreases down a group. The most electropositive element is fluorine. On the other hand, electropositivity decreases across a period from left to right but increases on going down a group. Hence, the most electropositive element is Francium. This also means that Francium is the least electronegative element,

francium belong to the group 1A of the periodic table which are the most reactive metals. The family of group 1A elements are known as alkali metals. They possess only one valence electron which they easily give up to form univalent positive ions or cations. Francium is a radioactive element.
