Question

H.w. balance the following equations:

a) Iron + chlorine → Iron (iii) chloride
b) Nitrogen + hydrogen → Ammonia
c) Phosphoric acid + sodium carbonate → sodium phosphate + water + carbon dioxide
d) Nitrogen dioxide + water + oxygen → Nitric acid

Answer 1

3iron + chlorine=iron3 chloride

nitrogen +3hydrogen

Answer 2

a) Iron + chlorine → Iron (iii) chloride

3fe+cl__fe3cl

b) Nitrogen + hydrogen → Ammonia

2N+3h2------2NH3

c) Phosphoric acid + sodium carbonate → sodium phosphate + water + carbon dioxide

2H3PO3+3Na2CO3-----2Na3PO4+3H2O+3CO2

d) Nitrogen dioxide + water + oxygen → Nitric acid

NO2+H2O+O2--NOH

sorry if mistake
