Complete the following calculations. Show working for complete credit :
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.
What do you mean by stoichiometry?
Calculate the mass and volume of oxygen at S.T.P., which will be evolved on electrolysis of 1 mole (18 g) of water.
When carbon dioxide is passed over red hot carbon, carbon monoxide is produced according to the equation :
\[\ce{CO2 + C -> 2CO}\]
What volume of carbon monoxide at S.T.P. can be obtained from 3 g of carbon?
How much volume will be occupied by 2 g of dry oxygen at 27°C and 740 mm 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:
- The pressure inside the tank is 800 mm of Hg.
- 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?
What temperature would be necessary to double the volume of a gas initially at s.t.p. if the pressure is decreased by 50%?
The following experiment was performed in order to determine the formula of a hydrocarbon. The hydrocarbon X is purified by fractional distillation.
0.145 g of X was heated with dry copper (II) oxide and 224 cm3 of carbon dioxide was collected at STP.
What was the purpose of Copper (II) oxide?
60 cm3 of oxygen was added to 24 cm3 of carbon monoxide and mixture ignited. Calculate the volume of carbon dioxide formed.
