Question

write the balanced chemical equation for the following reactions (i) calcium hydroxide + carbon dioxide gives rise to calcium carbonate + water
(ii)zinc + silver nitrate gives rise to zinc nitrate + silver

Answer 1

Ca(OH)2 + CO2 = CaCO3 + H2O
This a balanced equation in itself.
Zn + 2AgNo3 = Zn(NO3)2 + 2Ag
Thanks.

Answer 2

i)Ca(OH)2+co2------>CaCo3×H2o
ii)Zn+2AgNo3----->Zn(No3)2+2Ag
