50 ml of a gaseous mixture of hydrogen and hydrogen chloride was exposed to sodium amalgam. The volume decreased to 40 ml. if 10 ml of the same mixture is mixed with 5 ml of gaseous ammonia and then exposed to water, what will be the final volume (in ml) of gas left ? all the volumes are measured at the same temperature and pressure.

100mL of each hydrogen and oxygen was mixed and fired. What will be the final volume of the mixture when measured at the original conditions?

When 100 mL of ozonised oxygen is shaken with turpentine oil, volume decreases by 20 mL. when 100 mL of the same sample is heated, the mixture occupies a volume of 110 mL. determine the molecular formula of ozone. [All volumes are measured under same temperature and pressure.]

40 ml of gaseous mixture of CO and ethyne is mixed with 100 ml of O_2 and burnt. The volume of gases after combustion is 105 ml. The composition of the original mixture is

40 ml of gaseous mixture of CO and ethyne is mixed with 100 ml of O_2 and burnt. The volume of gases after combustion is 105 ml. The composition of 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].

10 mL of a gaseous hydrocarbon is completely combusted with 60 mL of oxygen by passing electric spark. The volume of the gaseous mixture thus yielded on cooling becomes 46 mL, iff the vapour density of the compound is 15, what will be its molecular formula? [All volumes were measured under the same conditions of temperature and pressure.]

Ten millilitre of a gaseous hydrocarbon is was exploded with oxygen. After the explosion, there was a contraction of 20 ml in volume. On shaking the residual gaseous mixture with KOH , there was a further concentration of 20 ml in volume. Calculate the molecualar formula. All the volumes were recorded at same temperature and pressure.

In 20 ml of a gaseous mixture containing N_2 and H_2 gases , 5 ml O_2 gas is added and the mixture is exploded. If the final volume becomes 13ml, then the only incorrect statement is : (All the volumes are measured at the same pressure and temperature )

20 ml of a gaseous mixture of N_2 and H_2 gases is mixed with 8 ml O_2 and the mixture is fired.if the final volume becomes 13 ml the volume percent of N_2 in the original mixture is :
