Answer:
The volume of the gas decreases also in a 21% based on the Avogadro's law
Explanation:
Based on Avogadro's law, the volume of a gas is directely proportional to the amount of moles of gas when temperature and pressure remain constants.
The formula is:
V1 / n1 = V2 / n2
<em>Where V is volume and n are moles in 1, initial state and 2, final state of the gas.</em>
<em />
At beginning, V1 = 100%, n1 = 100%,
As the chemist removes 21% of the gas, 79% of moles remain = n2.
Replacing:
100% / 100% = V2 / 79%
V2 = 79%, that means:
<h3>The volume of the gas decreases also in a 21% based on the Avogadro's law</h3>
Atom is the smallest indivisible particle of matter.
According to the table, I, LIBr releases energy as it dissolves.
<span>Lithium bromide is a synthesized compound of lithium and bromine. Its ultimate hygroscopic quality makes LiBr serviceable.</span>
The reaction will produce 12.1 g Ag₂S.
<em>Balanced equation</em> = 2Ag + S ⟶ Ag₂S
<em>Mass of Ag₂S</em> = 10.5 g Ag × (1 mol Ag/107.87 g Ag) × (1 mol Ag₂S/2 mol Ag)
× (247.80 g Ag₂S/1 mol Ag₂S) = 12.1 g Ag₂S
