How much carbon dioxide will be consumed to fully interact with calcium hydroxide in the amount of 3 mol.

Let’s execute the solution as follows:
1. Let’s write the equation:
Ca (OH) 2 + 2CO2 = Ca (HCO3) 2 – the reaction of the compound occurs when carbon dioxide is passed through lime water, calcium bicarbonate is formed;
2. Let’s make the proportion using these equations:
3 mol – Ca (OH) 2 – X mol (CO2);
– 1 mol – 2 mol, from which it follows: X mol (CO2) = 3 * 2/1 = 6 mol;
3. Determine the volume of CO2 according to Avogadro’s law:
V (CO2) = 6 * 22.4 = 134.4 liters.
Answer: to carry out the reaction, carbon dioxide in a volume of 134.4 liters was consumed.
