Answer:
4HCl(g)+O2(g)= 2H2O(g)+2Cl2(g)
∆H=-27.36 kcal
Explanation:
The balanced equation shows that four molecules of HCl reacts with one molecule of Oxygen to give two molecules of water and two molecules of chlorine gas and evolves energy in a combustion reaction.
Isotopes are substances that have the same number of protons but differ in the number of neutrons. Hence, the pair of isotopes above should be of the same element. In the given choices, 14C is not an isotope of 14N. 206Pb is an isotope of 208 Pb. O2 and O3 differ in molecular formula but still made up of same kind of atom, hence they are allotropes, while 32S and 32S2- are not isotopes.
