15 ~g of CaCO ₃ completely reacts with

Options

  1. A6.25 g of HCl
  2. B10.95 g of HCl
  3. C11.95 g of HCl
  4. D1.15 g of HCl

Correct answer

B. 10.95 g of HCl

Step-by-step solution

The balanced equation the reaction is 100 ~g CaCO ₃ + 73 ~g 2 HCl CaCl ₂+ H ₂ O + CO ₂100 ~g of CaCO ₃ completely reacts with 73 ~g of HCl aligned So, 15 ~g of CaCO ₃ will react with & = 73 100 15 ~g of HCl & =10.95 ~g of HCl aligned
