10 mL of a mixture of `CH_(4),C_(2)H_(4) and CO_(2)` was exploded with excess oxygen. After explosion, there ws a contraction of 17 mL on cooling and there was a further contraction of 14 mL on treatment with KOH. Find out the composition of the mixture.

100 cm^(3) of a mixture of CO, C_(2)H_(6) and N_(2) is exploded in presence of excess O_(2) . On cooling, the observed contraction in volume and the volume of CO_(2) formed are both equal to the volume original mixture. Find the volumetric composition of the original volume.

How will you isolate CH_(4) , C_(2) H_(4) and C_(2) H_(2) from their mixtures ?

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].

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].

A mixture contains CO, CH_(4) and nitrogen. 25cm^(3) of the mixture on oxidation in presence of excess oxygen, resulted in the decrease in volume by 16cm^(3) . A further contraction of 17cm^(3) was observed when the residual gas was treated with KOH soltuion. what was the composition of the original gaseous mixture of 25cm^(3) volume? [All volumes are measured at the same temperature and pressure].

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)

When an acetylenic hydrocarbon, in presence of excess oxygen is exploded, it shows a contraction in volume by 50 mL. a further contraction of 75 mL is observed when the obtained gas mixture comes in contact with KOH solution. Determine the molecular formula of the compound.

The volume of the gas mixture obtained by passing 400 mL CO_(2) over red hot coke was measured to be 600 mL. find the compo-sition of the gas mixture.

2 volumes of O_(3) produce 3 volumes of O_(2) on complete decomposition. 40 mL of a mixture of O_(3) and O_(2) is heated at first and then brought back to the previous temperature and pressure. The volume of the gaseous mixture is now found to be 42 mL. find the percentage composition of O_(3) in the gas mixture by volume. the volume of all gases are measured under the same conditions of temperature and pressure.

20 mL of a gaseous hydrocarbon is exploded with excess oxygen in an eudiometer tube and the contraction in volume was 70 mL. Vapour density of the hydrocarbon is 29. Find its molecular formula
