Both sides of the equation would be equal.

Answer:
The answer to your question is: more less
Explanation:
I suggest you these answers:
a) PCl₅ (s) ⇒ PCl₃ (s) + Cl₂ (g)
b) ZnBr₂ (aq) + Li₃CO₃ (aq) ⇒ ZnCO₃ (s) + LiBr (aq)
c) C₂H₄ + O₂ ⇒ CO₂ (g) + H₂O (l)
Do you have to balance them?
Moles of nitrogen = 49.84 / 28 = 1.78
Moles of hydrogen = 10.7 / 2 = 5.35
Molar ratio of nitrogen to hydrogen = 1 : 3
Hydrogen required = 1.78 x 3 = 5.34
Therefore, hydrogen is in excess and nitrogen is the limiting reagent.
