Determine the volume of evolved gas if in the reaction of CaCo3 with dilute HNO3, the amount

Determine the volume of evolved gas if in the reaction of CaCo3 with dilute HNO3, the amount of nanoic acid is consumed with a chemical amount of 0.2 mol. Reaction equation CaCO3 + 2HNO3 = Ca (NO3) + H2CO3.

Let’s carry out the solution in accordance with the conditions of the problem:
1. Let us write down the equation according to the problem statement:
Y = 2 mol. X l. -?
CaCO3 + 2HNO3 = Ca (NO3) 2 + CO2 + H2O – ion exchange, carbon monoxide is released (4);
2. Determine the number of moles of CO2, for this we make up the proportion:
0.2 mol (HNO3) – X mol (CO2);
-2 mol -1 mol hence, X mol (CO2) = 0.2 * 1/2 = 0.1 mol.
3. Find the volume of CO2 by applying Avogadro’s law:
V (CO2) = 0.1 * 22.4 = 2.24 l.
Answer: during the reaction, carbon dioxide is released in a volume of 2.24 liters.
