Question

How much carbon-di-oxide is libereted when
50gm of Calcium carbonat reacts with excess of
hy drochloric acid
CaCO3+ 2HCl gives rise to CaCl₂ + H₂O + CO₂
[Ca=40U, C = 12U,0=16U, H = 1U,Cl = 35.5U]
​

Answer 1

Answer:

answer will be 22 g

Explanation:

This is because total formula mass of CaCO3 is 100g however here 50g which means half is given so, If reactant is halved product will Also be halved. as molar mass of CO2 is 44
