Working

How to balance it, step by step

  1. Count each element on both sides. Every count already matches, so no coefficients are needed.
  2. Check: Ca 1 = 1, O 4 = 4, H 2 = 2, C 1 = 1. Balanced.
The reaction

What happens

It is a neutralisation reaction: an acid, or an acidic oxide, reacts with a base to give a salt and water. Whitewash is slaked lime. On the wall it slowly reacts with carbon dioxide in the air, and after two or three days it leaves a shiny coat of calcium carbonate.

Questions

Whitewash setting: quick answers

What is the balanced equation for whitewash setting?

Ca(OH)₂(aq) + CO₂(g) → CaCO₃(s) + H₂O(l). It is already balanced as written, so every coefficient is 1. Each side then has 1 Ca, 4 O, 2 H and 1 C.

What type of reaction is whitewash setting?

It is a neutralisation reaction: an acid, or an acidic oxide, reacts with a base to give a salt and water. Whitewash is slaked lime. On the wall it slowly reacts with carbon dioxide in the air, and after two or three days it leaves a shiny coat of calcium carbonate.

How do you balance Ca(OH)₂ + CO₂ → CaCO₃ + H₂O?

Count the atoms of each element on both sides: 1 Ca, 4 O, 2 H and 1 C. They already match, so no coefficients are needed.
