Determine the number of protons and the number of neutrons in a Carbon-14 isotope

6 protons and 8 neutrons (please help me with my questions too!)

Explanation:

The atomic mass is 18, if you subtract the atomic number ( the number of protons) to the atomic mass you get it.

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 !
