Dihydrogen reacts with dioxygen (O_(2)) to form water. Write the name and formula ofthe product when the isotope ofhydrogen which has one proton and one neutron in its nucleus is treated with oxygen. Will the reactivity of boththe isotopes be the same towards oxygen ? Justify your answer.

1.	Dihydrogen reacts with dioxygen (O_(2)) to form water. Write the name and formula ofthe product when the isotope ofhydrogen which has one proton and one neutron in its nucleus is treated with oxygen. Will the reactivity of boththe isotopes be the same towards oxygen ? Justify your answer.
Answer» Answer :`2H_(2) +O_(2) to 2H_(2)O` The isotope of hydrogen which has one proton and one neutron inits NUCLEUS is Deuterium . `2D_(2)+O_(2)to2D_(2)O` The product is heavy water (Deuterium oxide).`H_(2)O and D_(2)O`has same chemical properties but the reaction VELOCITY of `D_(2)O`is slightly LESS due to the difference in the mass number of theisotopes known as isotopic EFFECT. Deuterium is heavier than protium so reacts SLOWLY.
