Question

Write balanced molecular equations for the following word equations:
Calcium + oxygen → Calcium oxide
Calcium + water → Calcium hydroxide + Hydrogen
Zinc + Sulphuric acid → Zinc sulphate + hydrogen
Lead sulphate + ammonium hydroxide → Ammonium sulphate + lead hydroxide
Nitrogen + hydrogen → Ammonia
Mercuric oxide → Mercury + oxygen
Sulphur dioxide + oxygen → sulphur trioxide
Potassium nitrate → potassium nitrite + oxygen
Calcium nitrate → Calcium oxide + Nitrogen dioxide + oxygen
Magnesium + Hydrochloric acid → Magnesium chloride + Hydrogen

Answer 1

Answer:

1) 2Ca + O₂$\rightarrow$ 2CaO

2) Ca + 2H₂O $\rightarrow$Ca(OH)₂ + H₂

3) Zn + H₂SO₄ $\rightarrow$ ZnSO₄ + H₂

4) PbSO₄ + 2NH₄OH $\rightarrow$(NH₄)₂SO₄ + Pb(OH)₂

5) 2Hg + O₂ $\rightarrow$ 2HgO

6) 2SO₂ + O₂ $\rightarrow$ 2SO₃

7) 2KNO₂ + O₂$\rightarrow$ 2KNO

8) 2Ca(NO₃)₂$\rightarrow$ 2CaO + 4NO₂ + O₂

9) Mg + 2HCl $\rightarrow$MgCl₂ + H₂
