`50mL` of `CO` is mixed with `20mL` of oxygen and sparked. After the reaction, the mixture is treated with an aqueous `KOH` solution. Choose the correct option :

50 ml of CO is mixed with 20 ml of oxygen and sparked. After reaction, the mixture is treated with an aqueous KOH solution . Choose the correct option:

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-

25 mL of a gaseous hydrocarbon is mixed with 150mL of oxygen in an eudiometer. After sparking and cooling back the mixture is passed through alkaline pyrogallol. The volume loss surffered in pyrogallol is 25mL. Calculate the molecular weight of hydrocarbon.

20ml CO was mixed with 50 ml of oxygen and the mixture was exploded. On cooling, the resulting mixture was shaken with KOH. Find the final gaseous volume

20ml CO was mixed with 50 ml of oxygen and the mixture was exploded. On cooling, the resulting mixture was shaken with KOH. Find the final gaseous volume

30 mL of a mixture of CO and CO_(2) , mixed with 10 mL of oxygen, was exploded by electric spark. The gas mixture produced was mixed with KOH solution and thoroughly shaken. 5 mL of oxygen was left behind. What was the composition of the original mixture [volume was measured at STP].

50 ml of solution of pH = 1 is mixed with 50 ml of solution of pH = 2. The pH of the mixture is nearly :

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)
