1. Obtaining copper sulfate CuSO4.

Reaction between copper (II) oxide and strong acid:

CuO + H2SO4 = CuSO4 + H2O

Dissolving copper in a mixture of sulfuric and nitric acids:

3Cu + 3H2SO4 + 2HNO3 = 3CuSO4 + 2NO + 4H2O

Reaction of sulfur (II) oxide with sulfur (VI) oxide:

CuO + SO3 = CuSO4

The reaction of neutralization of copper (II) hydroxide with sulfuric acid:

Cu (OH) 2 + H2SO4 = CuSO4 + 2H2O

2. Obtaining sodium chloride NaCl.

Interaction of metallic sodium with chlorine when heated:

2Na + Cl2 = 2NaCl

Interactions of sodium with hydrochloric acid:

2HCl + 2Na = 2NaCl + H2

Neutralization of caustic soda with hydrochloric acid:

NaOH + HCl = NaCl + H2O

Interaction of hydrochloric acid with sodium carbonate:

2HCl + Na2CO3 = 2NaCl + H2O + CO2

3. Obtaining carbon dioxide CO2.

Burning carbon in oxygen:

C + O2 = CO2

Interaction of hydrochloric acid with sodium carbonate:

2HCl + Na2CO3 = 2NaCl + H2O + CO2

Decomposition of carbonic acid:

H2CO3 = H2O + CO2

Thermal decomposition of calcium carbonate:

CaCO3 = CaO + CO2
