2 Mole of $CO_{2}$ is required. Which of the following can be used to prepare it?

(Given : Atomic mass of Na = 23, H = 1, C = 12, O = 16, Ca = 40)

Answer:

A, D

Solution:

$2 N a H C O_{3} Δ N a_{2} C O_{3} + H_{2} O + C O_{2}$

$C a (H C O_{3})_{2} Δ C a C O_{3} + C O_{2} + H_{2} O$

$C a C O_{3} Δ + C a O + C O_{2}$

Thus, 1 mole of Ca(HCO₃)₂ can generate two moles of CO₂.
