What is the end result of a nuclear fusion reaction? two new atoms with smaller nuclei form molecule of atoms forms one new atom with a larger nucleus forms new bonds between atoms are formed

Option (c) is the correct answer.

Explanation:

When two small or light atomic nuclei combine together then it results in the formation of a larger nuclei.This process is known as nuclear fusion.

For example,

Whereas when a larger atomic nuclei splits into two small atomic nuclei then it is known as a nuclear fission.

For example,

Thus, we can conclude that the end result of a nuclear fusion reaction is one new atom with a larger nucleus.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

the answer is b & c i believe : )
