Question

IF 20g of CaCO3 is treated with 20g of HCl , How many grams of CO2 be produced given reaciton . CaCO3+HCl areeo CaCl2+H2O+CO2

Answer 1

Answer:

amount of co2 =8.8 g

Explanation:

according to the equation ,

for 100 g of caco3⇒ 73 g of hcl is needed

here we have 20 g of caco3 and 20 g of hcl,so the limiting reagent is caco3...so product formed will be according to the amount of caco3,

thus for 100 g of caco3⇒ 44g of co2 will be produced

that is for 1 g of caco3⇒44/100 g of co2

         so 20 g of caco3⇒ 44/100 × 20 of co2 formed

                                          =8.8 g
