100 gm mixture of Co and `CO_(2)` is mixed with 30 mL of `O_(2)` and sparked in eudiometer tube. The residual gas after treatment with aq. KOH has a volume of 10 mL which remains unchanged when treated with alkline pyrogallol . If all the volume are under the same conditions, point out the correct option(s)

100 mL of mixture of CO & CO_(2) is mixed with 30 mL of oxygen and sparked in eudiometer. Volume of residual gas after treatment with aqueous KOH was 10 mL which remains unchanged when treated with alkaline pyrogallate. Which of the following are correct-

9.0 mL of a mixture of CH_4 and C_2H_4 is mixed with 30.0 mL of O_2 and the mixture is exploded in an eudiometer tube. On cooling, the resulting gas mixture occupy a volume of 21.0 mL. on shaking the residual gas with KOH, the volume becomes 7.0 mL. Find the volumes of CH_4 and C_2H_4 in the mixture (All volumes are measured at the same temperature and pressure)

40 ml gaseous mixture of CO, CH_(4) and Ne was exploded with 10 ml of oxygen. On cooling, the gases occupied 36.5 ml. After treatment with KOH the volume reduced by 9 ml and again on treatment with alkaline pyrogallol, the volume further reduced, percentage of CH_(4) in the original mixture is

60 mL of a mixture of CO and H_(2) , mixed with 40 mL of O_(2) , are subjected to explosion in a eudiometer tube. On cooling the gas mixture after the end of the reaction, the volume is reduced to 30 mL. determine the compostion of the gas mixture initially taken. [All volumes are measured at the same temperature and pressure].
