5 g of CaCO3 completely reacts with

Question

5 g of CaCO3 completely reacts with (A) 36.4 g of HCl (B) 3.65 g of HCI (C) 0.365 g of HCI (D) 7.30 g of HCI.

The balanced equation for the reaction is:

100 g C a

C 0_{3}

+

73 g 2 H

C a C l_{2} + C O_{2} + H_{2} O

100 g of

C a C O_{3}

reacts completely with 73 g of HCl
So, 5 g of

C a C O_{3}

will react with

\frac{73}{100} \times 5 g

of HCl
= 3.65 g of HCI
