1 L of a mixture of CO and `CO_(2)`, when passed through red hot tube containing charcoal, the volume becomes 1.6 L. all volumes are measured under the same conditions of temperature and pressure. Find the composition of the 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.

Calculate the volume of O_(2) gas requried for complete burning of 10 L of acetylene gas. Also calculate the volume of CO_(2) produced. All volumes are measured at same temperature and pressure.

1 L of a gaseous element reacts with 2 L of another gaseous element to form 1 L of a gaseous compound (all volumes being measured under identical conditions of temperature and pressure). If both the element are diatomic and their symbols are X and Y respectively, then what will be the molecular formula of the compound.

Write whether the following statement is true or false: Under the same condition of temperature and pressure equal volumes of CO_2 and N_2 gas contain different number of molecules.

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.]

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].

What is the minimum volume of oxygen that must be mixed with 100 mL of carbon monoxide to convert it completely into carbon dioxde on explosion? Find the volume of carbon dioxidde formed at the same temperature and pressure. The volume of all gases are measured under the same conditions of temperature and pressure.

At 700 K, CO_2 and H_2 react to form CO and H_2O . For this process K is 0.11. [fa mixture of 0.45 mole of CO_2 and 0.45 mole of H_2 is heated to 700 K, then After equilibrium is reached another 0.34 mole of CO_2 and 0.34 mole of H_2 are added to the reaction mixture. Find the composition of the mixture at the new equilibrium state. (Assume volume to be 1 dm^3 )

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.
