In this task you will need to record the continuation of chemical reactions.
Na2O + H2O = 2NaOH.
Compound reaction. When sodium oxide interacts with water, sodium hydroxide is formed as a result.
CuSO4 + 2NaOH = Cu (OH) 2 + Na2SO4.
Exchange reaction. When copper sulfate reacts with sodium hydroxide, the result is copper hydroxide and sodium sulfate. Copper hydroxide forms a blue precipitate.
BaCl2 + H2SO4 = BaSO4 + 2HCl.
Exchange reaction. When barium chloride reacts with sulfuric acid, the result is barium sulfate and hydrochloric acid. Barium sulfate is white.
