If 6 litres of hydrogen and 4 litres of chlorine are mixed and exploded and if water is added to the gases formed, find the volume of the residual gas.


The equation given below relates the manufacture of sodium carbonate (molecular weight of Na2CO3 = 106).

  1. NaCl+NH3+ CO2+ H2O→ NaHCO3+NH4Cl
  2. 2NaHCO3→ Na2CO3+H2O + CO2

Equations (1) and (2) are based on the production of 21.2 g of sodium carbonate.

(a) What mass of sodium hydrogen carbonate must be heated to give 21.2 g of sodium carbonate?

(b) To produce the mass of sodium hydrogen carbonate calculate in (a), what volume of carbon dioxide, measured at S.T.P. would be required?


Water decomposes to O2 and H2 under suitable conditions as represented by the equation below:

\[\ce{2H2O -> 2H2 + O2}\]

If 2500 cm3 of H2 is produced, what volume of O2 is liberated at the same time and under the same conditions of temperature and pressure?


A gas is to be filled from a tank of capacity 10,000 litres into cylinders each having capacity of 10 litres. The condition of the gas in the tank is as follows:

  1. The pressure inside the tank is 800 mm of Hg.
  2. The temperature inside the tank is −3°C.

When the cylinder is filled, the pressure gauge reads 400 mm of Hg and the temperature is 270 K. Find the number of cylinders required to fill the gas.


Why is it necessary to compare gases at S.T.P?


Water decomposes to O2 and H2 under suitable conditions as represented by the equation below:

\[\ce{2H2O -> 2H2 + O2}\]

The 2500 cm3 of H2 is subjected to `2 1/2` times increase in pressure (temp. remaining constant). What volume will H2 now occupy?
