Answer 1

Calcium hydroxide = Ca(OH)2
Carbon dioxide =CO2
Calcium Carbonate = CaCO3
Water = H2O

Ca(OH)2 + CO2 → CaCO3 + H2O

Answer 2

First write down the compound formula:

Calcium hydroxide = Ca(OH)₂
Carbon dioxide= CO₂
Calcium Carbonate= CaCO₃
Water=H₂O

Write in the form of chemical equation:
Ca(OH)₂ + CO₂ → CaCO₃ + H₂O

Now balancing the reaction:
LHS                                                                      RHS
Ca=1                                                                   Ca=1   [balanced]
O=4                                                                       O=4   [balanced]
H=2                                                                       H=2   [balanced]
C=1                                                                       C=1   [balanced]

Number of elements of LHS=RHS
Hence, it is balanced.

Yipee since the equation is already balanced,nothing more to be done.
