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 :

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 )

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

When 20ml of mixture of O_(2) and O_(3) is heated the volume becomes 29ml and disappears in alkaline pyragallol solution. What is the volume percent of O_(2) in the original mixture ? .

When 20ml of mixture of O_(2) and O_(3) is heated the volume becomes 29ml and disappears in alkaline pyragallol solution. What is the volume precent of O_(2) in the originl mixture ? .

When 20ml of mixture of O_(2) and O_(3) is heated the volume becomes 29ml and disappears in alkaline pyragallol solution. What is the volume precent of O_(2) in the originl mixture ? .

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)

30 ml of a mixture of oxygen (O_(2)) and ozone (O_(3)) was heated till ozone was completely decomposed. The mixture on cooling was found to expand 40 ml. The volume of O_(2) in original mixture was :
