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 percent of O_(2) in the original mixture ? .

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 :

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 :

On subjecting 10ml mixture of N_(2) and CO to repeated electric spark to form CO_(2) and NO, 7 ml of O_(2) was required for combustion. What was the mole precent of CO in the mixture ? (All volumes were measured under identical conditions)

On subjecting 10ml mixture of N_(2) and CO to repeated electric spark to form CO_(2) and NO, 7 ml of O_(2) was required for combustion. What was the mole precent of CO in the mixture ? (All volumes were measured under identical conditions)

20 ml of a mixture of CO_(2) & C_(2)H_(4) was mixed with excess of O_(2) gas & was exploded. On bringing the solution back to the original room temperature a contraction of 12 ml was observed . What is the volume percentage of CO_(2) in the original mixture.

50 " mL of " ozone (O_3) at STP were passed through 50 " mL of " 5 volume H_2O_2 solution. What is the volume strength of H_2O_2 after the reaction?

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.

100 mL of ozone (O_3) at STP were passed through 100 mL of 10 volume H_2O_2 solution. What is the volume strength of H_2O_2 after the reaction?
