Mass of ammonium sulfate = 660.7 g
<h3>Further explanation</h3>
Given
3.01 x 10²⁴ molecules of ammonium sulfate
Required
mass
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
mol ammonium sulfate (NH₄)₂SO₄ :
n = N : No
n = 3.01 x 10²⁴ : 6.02 x 10²³
n = 5
mass ammonium sulfate :
= mol x MW
= 5 x 132,14 g/mol
= 660.7 g
The equilibrium shifts to the side having the lesser volume or number of moles
Explanation:
Reaction 2N₂
+ 3H₂
⇄ 2NH₃
This reaction, haber process is completely a combination of gaseous molecules.
An increase in pressure will shift the equilibrium position to the right hand side i.e the side with the lesser volume or number of moles.
Number of moles
Reactants Products
5 2
The product side has a lesser number of moles and the equilibrium shifts to the right hand side.

Answer:
Cl2, Chlorine molecule has a boiling point closest to that of argon.
This is because Chlorine is made up of discrete and simple molecules making up a simple molecular structure. The molecules associate through weak van der waal's forces of attraction hence low boiling point.
HCl <em>has</em><em> </em><em>strong</em><em> </em><em>hydrogen</em><em> </em><em>bonds</em><em>.</em>
F2 <em>is</em><em> </em><em>very</em><em> </em><em>small</em><em> </em><em>hence</em><em> </em><em>strong</em><em> </em><em>forces</em><em> </em><em>of</em><em> </em><em>attraction</em><em>.</em>

Answer:
4Al + 3O₂ → 2Al₂O₃
Explanation:
4Al + 3O₂ → 2Al₂O₃
Only this reaction above obeys the law of conservation of mass. The others flout the rule.
The law of conservation of mass states that "matter is neither created nor destroyed in a chemical reaction but are simply transformed from one form to another".
By this law, the number of atoms on both sides of expression must be the same;
Number of atoms
Elements Left hand side Right hand side
Al 4 4
O 6 6
