Answer:

Electrons are trapped inside the atom because of the attraction forces with positively charged protons that are found in the nucleus.

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%

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

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.

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.

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).

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).
