Question

In an activity to conduct the composition of air, a gas jar stand is placed in a trough of water in which a substance P has been dissolved. A burning candle is fixed on the gas jar stand and a gas jar is inverted over the burning candle. After sometime, the burning candle gets extinguished and water from the trough rises to fill one-fifth of the inverted gas jar. The water rises in the gas jar because the product Q formed by the burning of candle in air gets dissolved in solution of P in water. A gas R is left behind in the inverted gas jar. What are P, Q, and R?
