Question

No.of mole of $C{O}_2$ produce when $3mole$ HCI react with excess of $CaC{O}_3$ is:

• A. $1$
• B. $1.5$
• C. $2$
• D. $2.5$

Answer 1

Answer: (B)

$1.5$

$CaC{O}_3+2HCl=C{O}_2⟶CaC{l}_2+H_{2}O$

In this above reaction, $2$ moles of $HCl$ reacts with $CaC{O}_3$ to form $1$ mole of $C{O}_2$ .

$\therefore 3$ moles of $HCl$ produces $1.5$ moles of $C{O}_2$ .
