Answer:
(a)
Moles of ammonium chloride = 0.5 mole
Mass of ammonium chloride formed = 26.7455 g
(b)
Mole of = 0.125 mole
Mass = Moles * Molar mass = 0.125 * 76.139 g = 9.52 g
Mole of = 0.25 mole
Mass = Moles * Molar mass = 0.25 * 34.1 g = 8.525 g
Explanation:
(a)
For the first reaction:-
The mole ratio of the reactants = 1 : 1
0.5 moles of ammonia react with 0.5 moles of hydrochloric gas to give 0.5 moles of ammonium chloride
So, <u>Moles of ammonium chloride formed = 0.5 moles</u>
Molar mass of ammonium chloride = 53.491 g/mol
<u>Mass = Moles * Molar mass = 0.5 * 53.491 g = 26.7455 g</u>
(b)
For the first reaction:-
The mole ratio of the reactants = 1 : 4
It means
0.5 moles of methane react with 2.0 moles of sulfur to give 0.5 moles of Carbon disulfide and 1.0 moles of hydrogen sulfide gas.
But available moles of S = 0.5 moles
Limiting reagent is the one which is present in small amount. Thus, S is limiting reagent.
The formation of the product is governed by the limiting reagent. So,
4 moles of S produces 1 mole of
Thus,
0.5 moles of S produces mole of
<u>Mole of = 0.125 mole</u>
Molar mass of = 76.139 g/mol
<u>Mass = Moles * Molar mass = 0.125 * 76.139 g = 9.52 g</u>
4 moles of S produces 2 moles of
Thus,
0.5 moles of S produces mole of
<u>Mole of = 0.25 mole</u>
Molar mass of = 34.1 g/mol
<u>Mass = Moles * Molar mass = 0.25 * 34.1 g = 8.525 g</u>

<u>Answer:</u> Boyle's law states that gas volume is inversely proportional to pressure.
<u>Explanation:</u>
Boyle's law is one of the law used to determine the Ideal Gas equation.
This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles
Mathematically,
(at constant temperature and number of moles)
The above expression can also be written as:
where,
are initial pressure and volume of the gas
are final pressure and volume of the gas
Hence, Boyle's law states that gas volume is inversely proportional to pressure.
