Make the equation: 1) nitric acid + iron (III) hydroxide → iron (III) nitrate + water

Make the equation: 1) nitric acid + iron (III) hydroxide → iron (III) nitrate + water 2) copper (II) oxide + ammonia (NaH2) → copper + nitrogen + water

1) 3HNO3 + Fe (OH) 3 = Fe (NO3) 3 + 3H2O – this reaction refers to neutralization reactions or exchange reactions, as a result of which hydrogen atoms change places with iron atoms. The hydroxide reacts with the acid to form salt and water.
2) 3CuO + 2NH3 = N2 + 3Cu + 3H2O – this reaction refers to exchange reactions, as a result of which a compound of copper with nitrogen is formed, which is not stable and immediately decomposes into metallic copper and nitrogen gas, water is also formed. In this reaction, three states of matter are formed: solid copper, liquid water and nitrogen gas.
