Question

20 g of CaCO3 reacts with 20 g of HCl according to following equation:

CaCO3 + 2HCl CaCl2 + H2O + CO2

Calculate the amount of CO2 formed.
.​

Answer 1

Answer:

8.8g Co2

Explanation:

20 gram of CaCO3 will react with 73/100 *20 g HCl = 14.6 g. HCl only to give CO2. So the limiting reagent is CaCO3. therefore 20 g of CaCO3 will give = 44/100 *20 = 8.8 g CO2

Answer 2

Explanation:

20 gram of CaCO3 will react with 73/100 *20 g HCl = 14.6 g. HCl only to give CO2. So the limiting reagent is CaCO3. therefore 20 g of CaCO3 will give = 44/100 *20 = 8.8 g CO2
