Question
CBSEENCH11006975

Give reason for the fact that a mixture of H2O2 and hydrazine (H2NNH2) is used as propellant.

Solution
straight H subscript 2 straight O subscript 2 oxides H2N NH2 to free nitrogen and water.
straight H subscript 2 straight N. space NH subscript 2 left parenthesis straight l right parenthesis space plus space 2 straight H subscript 2 straight O subscript 2 left parenthesis straight l right parenthesis space rightwards arrow space space straight N subscript 2 left parenthesis straight g right parenthesis space plus space 4 straight H subscript 2 straight O left parenthesis straight g right parenthesis space plus space Heat

The reaction is exothermic and the products being gases at the temperature of reaction, there is a tremendous increase in pressure. Hence this mixture is used as a rocket propellant.
