A mixture of `CO_2`and CO of volume 1 litre on passing through a tube containing red hot charcoal becomes 1.6 litres measured at same temperature and pressure. Calculate the composition of the gaseous mixture.

One litre of a mixture of carbon mono oxide and carbon dioxide is passed through a tube containing red hot charcoal. The volume becomes 1.6 litres. Find the composition of the gaseous mixture.

What volume of HCl gas formed when 10 litre of H_2 gas is allowed to completely react with 10 litre of H_2 gas and 10 litre of Cl_2 gas at the same temperature and pressure.

If the pressure and temperature of 2 litre of CO_2 are doubled, the volume of CO_2 would become :

A gaseous mixture of 3L of propoane and butane on complete combustion at 25^@C produced 10 L CO_2 . Find out composition of the gaseous mixture.

1.0 gm of mixture of CaCO_3 and MgCo_3 on one complete of decomposition gave 240 ml of CO_2 at NTP. Calculate the percentage composition of mixture.

500mL of a hydrocarbon gas burnt in excess of oxygen yielded 2500 mL of Co_2 and 3.0 liter of water vapour (all volumes measured at the same temperature and pressure). The formula of the hydrocarbon is :

A and B are two identical vessels. A contains 15 g of ethene at 298 K and 1 atm. The vessel B contains 75 g gas X_2 at the same temperature and pressure. The vapour density of X_2 is :

1.0 gm of an alloy of aluminium and magnesium when treated with excess of dilute HCl forms magnesium chloride aluminium chloride and hydrogen. The evolved hydrogen collected over mercury at 0^@C has a volume of 1.20 litres at 0.92 atm pressure Calculate the composition of alloy.[Al = 27 , Mg=24.3]

40% of a mixture of 0.2 mole of N_2 and o.6 mole of H_2 react to give NH_3 according to the equation: N_ 2 ( g ) + 3 H_ 2 ( g ) ⇔ 2 N H_ 3 (g) at constant temperature and pressure. Then what is the ratio of the final volume to the initial volume of gases ?
