b) Aluminium + copper chloride --> Aluminium chloride + copper
c) Potassium + water --> potassium hydroxide + hydrogen
d) Hydrogen + Bromine --> Hydrogen bromide
e) Ethanol burns in air to form carbon dioxide, water and heat.

Answer 1

Answer:

Explanation:

A. BaCl2+ K2SO4→ BaSO4+ KCl.

IT IS PRECIPITATION REACTION AND DOUBLE DISPLACEMENT REACTION.

2. Al+ CuCl2→ AlCl3+ Cu, SINGLE DISPLACEMENT REACTION.

3. K+ H20→ KOH+ H2, SINGLE DISPLACEMENT REACTION.

4. H2+ Br2→ 2HBr, COMBINATION REACTION.

5. C2H5OH+O2→ CO2+ H2O+ HEAT, COMBUSTION REACTION.
