Write the equations of all possible reactions between the following substances

Write the equations of all possible reactions between the following substances: barium nitrate, sodium hydroxide, copper sulfate, hydrochloric acid

1) Ba (NO3) 2 + CuSO4 = Cu (NO3) 2 + BaSO4
Formation of two salts of copper nitrate and barium sulfate, which gives a white precipitate.

2) NaOH + HCl = NaCl + H2O
Neutralization reaction to form soluble salt and water.

3) CuSO4 + 2NaOH = Na2SO4 + Cu (OH) 2
Precipitation reaction of copper hydroxide (blue color of the solution).

4) CuSO4 + НCl ≠ the reaction will not go.
The salt is formed by the acid H2SO4, which is stronger than HCl.
