It’s B the cu looses its 2 and passes it to the NH3 that needs a bracket to separate them. The NH3 doesn’t loose its 3 because it’s already a compound!
Hope this helps!
The enthalpy of reaction or ∆H reaction is the difference between the bond energy of the reactants and the bond energy of the products.
<h3>What is ∆H reaction?</h3>
The term ∆H reaction refers to the heat that is evolved or absorbed in a chemical reaction. It is also known as the enthalpy of reaction.
The question is incoherent but I will try to answer as much as possible. Using the values of bond energy, ∆H reaction = Bond energy of reactants - bond energy of products. This will give us the enthalpy of reaction.

Explanation:
firstly firstly we are to calculate the number of moles of ammonia and using the mole concept of two moles of ammonia gives one mole of ammonium sulphate we can calculate the number of moles of ammonium sulphate and mass
from n=m/mr
Answer:
The closer you are to the Equator the hotter the temperature will get, and the further you are from the Equator the colder it will get.
