Question

Complete the following chemical equations:
(1) CO₂ + …… → C₆H₁₂O₆ + ..... + H₂O
(2) CaCO₃ + ...... + ...... → CaH(CO₃)₂
(3) CuSO₄ + ....... <—?—> CuSO₄ .5H₂O

Answer 1

Chemical equations

Explanation:

1) 6CO2 + 12H2O + photons → C6H12O6 + 6O2 + 6H2O

The equation represents photosynthesis in plants where carbon dioxide + water + light energy forms glucose.

2) CaCO3 + CO2 + H2O → Ca(HCO3)

Calcium bicarbonate is formed when calcium carbonate reacts with carbon dioxide and water.

3) CuSO4(s) + 5H2O ⇋ CuSO4.5H2O (s)  

When water is added to copper sulphate crystals, we get copper(2+) sulphate pentahydrate, a bright blue crystalline solid. This is a reversible reaction.
