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.

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.

What is the volume of 11g of CO_(2) at STP?

The ratio of the volume of CO_(2) evolved to the volume of O_(2) consumed in respiration is called

Volume of CO_2 produced at STP from 1 mole of calcium carbonate is-

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)

" 20 volume" of H_2O_2 is equal to

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.

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].

A mixture of formic acid and oxalic acid is heated with concentrated H_(2)SO_(4) . The gas evolved is collected and treated with KOH solution. The volume of the solution decreases by 1/6 th of its original volume. Find the molar ratio of the two acids in the original mixture.
