उत्तर

\[\ce{2C2H2 + 5H2O -> 4CO2 + 2H2O(l)}\]

2 vol. of C2H2 need O2 = 5 vol.

From equation, 2V of C2Hrequires = 5 V of O2

So, for 400ml C2H, O2 required = `400 × 5/2`

=1000 ml

Similarly, 2 V of C2H2 gives = 4 V of CO2

So, 400ml of C2H2 gives CO2 = `400 × 4/2`

∴ Volume of carbon dioxide formed = 800ml
