Answer:

Below!

Explanation:

Isotopes are elements with a similar chemical makeup and the same atomic number, but a different atomic mass and number of neutrons . An example of this would be carbon-12, carbon-13, and carbon-14. Three isotopes of the element carbon that have the same 6 protons but have a different neutron count. A simple way to explain isotopes would be to say that they are just different "versions" of an element.

Hope this helps ya! Best of luck <3

Answer:

Explanation:

1. Please provide the enthalpy info - I will work on it with the info

i) Reaction a should be modified to match the number of S in equation:

2S + 2O2 -> 2SO2 deltaH = -370kJ

ii) Reaction b should be written reversely to match the reactants of SO2:

2SO2 + O2 -> 2SO3 deltaH = 256kJ

iii) Adding the equations together:

2S + 3O2 -> 2SO3
