Question

N2H4 and H2O2 are used as a rocket fuel.The product of the reaction are nitrogen a d water.How many grams of H2O2 are needed per kg of N2H4 carrying by the rocket​

Answer 1

Answer:

1 kg

Explanation:

Answer 2

$\huge\underline\mathfrak\red{Answer}$

N_2H_4 is hydrazine and H_2O_2 is hydrogen peroxide. When these two substances react nitrogen gas and water are produced according to the following equation:

N_2H_4 + 2 H_2O_2-> N_2 + 4 H_2O

This reaction is highly exothermic, meaning that a large amount of heat is released. Due to the high temperature the water produced is in the gas phase. The rapid generation of the two gases from two liquids makes this reaction useful for propelling rockets. However, hydrazine is very unstable in the liquid form and must be handled with care. It's used as a foaming agent and as a precursor to other chemicals, particularly pharmaceuticals, in manufacturing.

Hydrogen peroxide is known as a strong oxidizer. Oxygen goes from the -1 oxidation state in hydrogen peroxide to the -2 in water. Nitrogen is oxidized from the -1 state to the zero state.
