N2H4 (Hydrazine) is a rocket fuel, it burns in O2 to give N2 and H2O N2H4 + O2 N2 + 2H2O

1.00 g of n2h4 is burnt in a bomb calorimeter an increase of temperature 3.51° C is recorded. The specific heat of calorimeter is 5.5 J k⁻¹ g⁻¹ . Calculate the quantity of heat evolved also calculate the heat of combustion of one mole of N2H4

The picture represents the process that produces most of the energy used by living organisms on earth. which process is represented in the picture? a) the magnetic attraction between two hydrogen nuclei. b) the fusion of hydrogen nuclei to produce a helium nucleus in the core of the sun. c) the fission of hydrogen nuclei to produce a helium nucleus in the core of the sun. d) the chemical reaction between hydrogen nuclei to produce a helium nucleus in earth's atmosphere.
