What volume of CO(2) at STP is obtained ...

What volume of `CO_(2)` at `STP` is obtained by thermal decomposition of `20g KHCO_(3)` to `CO_(2)& H_(2)O` [Atomic mass `K = 39]` .

Text Solution

Verified by Experts

Write balanced reaction : `{:(2KHCO_(3)(s),overset(Delta)rarr,K_(2)O(s)+,2CO_(2)(g),+H_(2)O(g)),(20g=0.2mol,,0.2mol,,):}`
Vol of `CO_(2) = 0.2 xx 22.4 = 4.48 L` .
