A mixture of 10 cm3 of methane and 10 cm3 of ethane was sparked with an excess of oxygen. After cooling to room temperature, the residual gas was passed through aqueous potassium hydroxide. What volume of gas was absorbed by the alkali?

Walen:

by alkali do u mean the potassium hydroxide?

Walen:

also galaxy the first step would be to write down the reaction

Walen:

methane is CH4 ethane is C2H6 if im not dumb it should come to C2H6(g) + CH4(g) + O2 => 3CO2 + 5H2O

Walen:

and like the copy paster said yes. translate it to volume under the current conditions and u get 30cm^3 of CO2
