Given solutions of substances: nitric acid, coal, copper (II) oxide, ammonia. Write the equations for four possible reactions between these substances.

We are given chemical substances: nitric acid – HNO3, coal – C, bivalent copper oxide – CuO, ammonia – NH3. Let’s write the equations of chemical reactions between these substances.

1) Nitric acid and ammonia enter into a chemical reaction and we end up with the ammonium nitrate salt.

HNO3 + NH3 = NH4NO3

2) A chemical reaction takes place between substances such as carbon (carbon) and nitric acid. As a result of this interaction, we get tetravalent carbon monoxide, tetravalent nitric oxide and water.

C + 4 HNO3 = CO2 + 4 NO2 + 2 H2O

3) Copper oxide reacts with ammonia and forms nitrogen, copper and water.

3 CuO + 2 NH3 = N2 + 3 Cu + 3 H2O

4) Carbon and copper oxide, after passing through a chemical reaction, form carbon monoxide and pure copper.

C + CuO = CO + Cu.
