Calculate the volume of carbon dioxide at NTP evolved by strong heating of 20g calcium carbonate.

Text Solution

Verified by Experts

The balanced equation is : `{:(CaCO_(3), to, CaO + CO_(2)),(1 mol,," "1 mol),(100 g ,," "=22.4" litreat NTP"):}`
100 g of `CaCO_(3)` evolve carbon dioxide ` = 22.4` litre
20 g `CaCO_(3)` will evolve carbon dioxide
` = (22.4)/100 xx 20 = 4.48` litre
