Question

the number of moles of CO2 produced when 3 moles of HCL react with excess of CaCo3
is

Answer 1

2 moles of HCl  produces 1 mole of CO₂. 
Therefore 3 moles will produce 1.50 moles.

Answer 2

Answer:

1.5

Explanation:

the equation is

CaCO3 + 2HCl =>CaCl + CO2 + H2O

then 2 moles of HCl gives 1 mole of CO2

for 3 moles of HCl gives = 3/2=1.5
