Answer:

HI FRIEND HERE IS YOUR ANSWER ,

Generated mass of  during in the given reaction is 8.8 g.

Explanation:

Balanced reaction:  

From the reaction,  

1 mole of calcium carbonate reacts with 2 moles of Hydrogen chloride and produce 1 mole of carbon dioxide.

Let’s calculate the moles of ¬:

Molar mass of  = 100 g/mol

Given mass of = 20 g

Moles of

0.20 mol of  reacts with 0.4 mol of HCl

Let’s calculate the moles of HCl:

Molar mass of HCl = 36.45 g/mol

Given mass = 20 ml

Moles of HCl=

Therefore,  is limiting reagent.

0.20 mol of  gives 0.20 mol of

Molar mass of  = 44 g/mol

Mass of CO2 produced=0.2x44g/mol=8.8g
