O The scientist is investigating Charles's law, which shows that temperature and volume are inversely proportional.

Answers

Answer 1

The statement which describes the experiment best is,the scientist is investigating Charles's law, which shows that temperature and volume are directly proportional.

What is Charles's law?

It states that the volume of a given mass of gas is directly proportional to its absolute temperature when pressure is held constant. It states that the volume of a given mass of gas is directly proportional to its absolute temperature when pressure is held constant. In other words, if the temperature of a gas increases, its volume will also increase. This relationship was first described by French scientist Jacques Charles in 1787. He based his law on the results of experiments he conducted with varying amounts of gas. Charles's Law is one of the gas laws, which were used to formulate the ideal gas law. This law is especially useful for understanding how gases behave under various conditions, such as changes in temperature and pressure. It is also important to note that Charles's Law does not apply to liquids and solids as they are not gases.

If 3.68 grams of zinc were allowed to react with excess hydrochloric acid to produce zinc chloride and hydrogen gas, how much zinc chloride should be produced?

Suppose that 7.12 grams of zinc chloride is actually recovered, what is the per cent yield?

Answers

Answer:

Here... Since there is excess HCl, you know the Zinc will be the limiting reagent.  I was able to create the reaction equation based on the info you gave: Z + 2HCl ----> ZCl2 +2H.  Now, in order to find the theoretical yield of ZCl, you need to convert Zinc from grams to moles.  Do this by dividing by its molar mass (65.38), thus: 3.68 (g) / 65.38 (g/mol) = 0.056286... moles.  

Now, using the balanced equation we made earlier, we see that 1 mole of Zinc creates 1 mole of ZCl2.  Thus our ratio is 1:1.  This makes the next step easy.  Since it is 1:1, we multiply the number of moles we have of Zinc (0.056286...) by the number of moles it will create of ZCl (1).  (0.056286)(1) = 0.056286 moles ZCl.  Now convert this to grams by multiplying by its molar mass (136.28) and you get 7.67 grams.  This is your theoretical yield.  The percent yield is found by dividing the actual amount obtained (7.12 g.) by the theoretical yield (7.67 g.) then multiply that by 100%.   When this is done, your Percent Yield is about 92.8%

is there a relationship between the relative age of stars in the number/identity of element is found within them

Answers

Yes. Stars use fusion to create nuclear energy, which is what makes them "alive". The older they are, the "bigger" the element in them is. Hydrogen turns into Helium, and when hydrogen is used up, the helium starts fusing into bigger elements. it stops at iron however. Once stars start fusing silicon to iron, it is doomed because it takes more energy than it gives off.

How many atoms are in 2.54 mole O?

Answers

Answer:  1.505 * 10^24 atoms

========================================================

Work Shown:

1 mole = 6.02 * 10^23 atoms

2.5*(1 mole) = 2.5*(6.02 * 10^23 atoms)

2.5 moles = (2.5*6.02) * 10^23 atoms

2.5 moles = (15.05) * 10^23 atoms

2.5 moles = (1.505 * 10^1) * 10^23 atoms

2.5 moles = 1.505 * (10^1*10^23) atoms

2.5 moles = 1.505 * 10^(1+23) atoms

2.5 moles = 1.505 * 10^24 atoms

This is true for any element. This value is an approximation since there are roughly 6.02 * 10^23 atoms in 1 mole of any element.

The highest pressure ever produced in a laboratory setting was about 2.0 x 10 6 atm. If we have a
1.0 x 10 -5 liter sample of a gas at that pressure, then release the pressure until it is equal to 0.275 atm,
what would the new volume of that gas be?

Answers

Answer:

Volume = 72.7272

Explanation:

if only pressure and volume change, then we can do some simple math to find the answer.

2 x 10 ^ 6 times 1 x 10 ^-5 = 20

pressure and volume must equal 20

20 = 0.275 x volume

20 / 0.275 = new volume

I don't remember significant digits but your volume is 72.72727272 just repeated

If we have a 1.0 x 10 -5 liter sample of a gas at that pressure, then release the pressure until it is equal to 0.275 atm, the new volume will be 72.7272

What is Volume?

Volume is the space occupied by a three-dimensional object.

By the Boyle's law

[tex]\rm P_1V_2= P_1V_2[/tex]

P1 (initial pressure) = [tex]2.0 \times10^6 atm[/tex]

V1 (initial volume) = [tex]1.0 \times10^-5 L[/tex]

P2 (final pressure) = 0.275 atm

V2 (final volume) = ? (in L)

Putting the values in the equation

[tex]\rm 2.0 \times10^6 atm \times 1.0 \times10^-5 L = 0.275 atm \times V_2\\\\V_2 = \dfrac{20}{0.275} = 72.72 L[/tex]

Thus, the volume is 72.72 L.

Answers

Answer:less than

Explanation:

If we had 79.3 grams of Xe, we would expect a volume that is less than obtained with neon. So, the correct option is (C).

What is Density?

Density is defined as the mass per unit volume of a substance. The most commonly used symbol for density is ρ, although the Latin letter d can also be used. Density is defined as mass divided by volume:

[tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]

where ρ is density,

m is mass, and

V is volume.

The mass contained per unit volume of an object is known as density. where the SI unit of density is kilogram per cubic meter [tex](kg/m^3).[/tex] Density is inversely proportional to volume, so the density of Xenon is [tex]5.894 kg/m^3[/tex] while the density of neon is 0.89994 kg/m³. So, if density is more than volume will be less and vice versa. In this case, density of Xenon is more as compare to neon so, the volume of neon will be more.

Thus, if we had 79.3 grams of Xe, we would expect a volume that is less than obtained with neon. So, the correct option is (C).

Each element... A. Has only one kind of atom B. Has only one kind of molecule C. Is made of rock D. All of the above

Answers

Answer:

A. Has only one kind of atom

Explanation:

All forms of matter are composed of elements.

An element is a substance which cannot be broken down into simpler units or converted into other substances by ordinary chemical reactions. Each element is composed of only one kind of atoms which are unique to each element. There are three fundamental sub-particles present in atoms of elements; these are: protons, electrons and neutrons. An atom of an element differs from an atom of another element by its atomic number. The atomic number of an element is the number of protons present in the nucleus of the atom of that element. For example, hydrogen atoms has an atomic number of 1, while sodium atoms has an atomic umber of 11.

Atoms of the same element or different elements may combine together to form the molecules of a substance. For example, a molecule of hydrogen gas is made up of two atoms of hydrogen whereas a molecule of water is composed of two atoms of hydrogen and an atom of oxygen.

Elements can exist in any of the three physical states: solids, liquids or gases. For example, hydrogen exists as gas, mercury as a liquid, while gold exists as a solid.
