(In \(g\)) \(CaCO _{3( s )}+2 HCl _{( aq )} \rightarrow \)\(CaCl _{2( aq )}+ CO _{2( g )}+2 H _{2} O _{( l )}\) [Calculate upto second place of decimal point]

  1. A \(1.32\)
  2. B \(3.65\)
  3. C \(9.50\)
  4. D \(1.25\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(1.32\)

Step-by-step Solution

Detailed explanation

\(CaCO _{3(s)}+2 HCl _{(\text {aq) })} \rightarrow \)\(CaCl _{2(a q)}+ CO _{2(q)}+ H _{2} O _{(q)}\) no. of moles of \(CaCO _{3}\) (pure) \(=\frac{1}{2} \times\) mole of \(HCl\)
