Answer 1

Answer:

Explanation:

Marsh gas (CH4) exploded with oxygen

CH4 + 2O2 -------->   CO2   +2H2O

1vol.    2vol.               1vol.      0vol.

24cc    48cc              24cc

1vol.of CH4 required O2 = 2vol.

24cc of CH4 required O2 = 24*2 = 48cc

also 24cc of CH4 produce CO2 = 24cc

Vol.of O2unused = 106-48 = 58cc

Vol. of mixture on cooling= (unused O2 + CO2 formed)

                                         = 58+24 = 82cc
