This is a short answer type question as classified in NCERT Exemplar
Dihydrogen reacts with dioxygen to form water. The reaction is highly exothermic.
H2 (g) + O2 (g) → H2O (l)
? H = -285.9KJmol-1
The isotope of hydrogen which has one proton and one neutron is deuterium. When it reacts with O2 it forms Deuterium oxide (D2O). Deuterium reacts in a similar way but the reactivity will be lesser than hydrogen because of high bond dissociation enthalpy of D2 as compared to hydrogen.
