प्रश्न
66g of ammonium sulphate is produced by the action of ammonia on sulphuric acid. Write a balanced equation and calculate the mass of acid required.
उत्तर
\[\ce{2NH3 + H2SO4 -> [NH4]2SO4}\]
Mass of acid required for 132 g (NH4)2SO4 = 98 g
∴ Mass of acid required for 66 g (NH4)2SO4
= `(98 xx 66)/132`
= 49 g

LPG stands for liquefied petroleum gas. Varieties of LPG are marketed including a mixture of propane (60%) and butane (40%). If 10 litres of this mixture is burnt, find the total volume of carbon dioxide gas added to the atmosphere. Combustion reaction can be represented as:
\[\ce{C3H8_{(g)} + 5O2_{(g)} -> 3CO2_{(g)} + 4H2O_{(g)}}\]
\[\ce{2C4H10_{(g)} + 13O2_{(g)} -> 8CO2_{(g)} + 10H2O_{(g)}}\]
