Answer

a

Explanation

(A) `CaCO_3overset Delta underset ("decomposition")toCa+CO_2(22.4l)`
Decomposition of 100 g of `CaCO_3` gives` 22.4 LC)_2`
Decompossition of 10 g of `CaC)_3` will give,
`(22.4xx10)/(100)=2.24L CO_2`
(B) ` underset((106 g))Na_2CO_3+2HCl+H_2O+CO_2underset((22.4L))`
Excess HCl addeed to 106 g of `NaCO_2`will give,`(22.4xx1.06)/(106)=0.224L CO_2`
(C)` underset ((12g))C+O_2 toCO_2(22.4L)`
Combustion of 12g of carbon with oxygen will<>br give`(22.4xx2.4)/(12)=4.48L CO_3`
(D) ` COoverset ("Excess O_2")underset("Combustion")toCO_2 underset((22.4L))`
Balanced equation `:2CO+O_2 to2CO_2(2xx22.4L)`
Combustion of 56g of carbon monoxide with oxygen gives `2xx22.4 L CO_2`
0.56g of carbon monoxide will give `(2xx22.4xx0.56)/(56)=0.448L CO_2`
`therefore A-(iv),B-(i),C-(ii),D-(iii)`
