Question : 26 of 86

Marks: +1, -0

The amount of each reactant required to produce

750 {\ml}

of carbon dioxide, when two volumes of carbon monoxide combine with one volume of oxygen to produce two volumes of carbon dioxide.

2 {\CO}+ {\O}_2 → 2 {\CO}_2

Solution:

2 {\CO}+ {\O}_2\;→\;2 {\CO}_2

2\;\;\;\;\;:\;\;\;\; 1 \;\;\;:\;\;\;\;2

(1) If 2 vol. of

{\CO}_2

is produced from 2 vol. of

{\CO}

Then

750 {\ml}

{\CO}_2

is produced from

=\;{2}/{2} × 750=750 {\ml} \;\text " of "\; {\CO}

(2) If 2 vol. of

{\CO}_2

is obtained from 1 vol. of

{\O}_2

Then

750 {\ml}

{\CO}_2

is obtained from

=\;{1}/{2} × 750=375 {\ml}

{\O}_2
