1. Solid sodium cyanide is added to liquid water to produce hydrogen cyanide gas and sodium hydroxide.

NaCN + H2O → HCN + Na(OH)

2. Solutions of lead (II) nitrate and potassium carbonate are mixed to produce lead (II) carbonate precipitate and potassium nitrate.

Pb(NO3)2 + K2CO3 → PbCO3 + 2 KNO3

3. Liquid ethanol is burned in oxygen gas. The products are carbon dioxide gas and water vapor.

C2H5OH + 3 O2 → 2 CO2 + 3 H2O
