Protons are positively charged and repel other protons. which other particle is found in the nucleus and separates protons so that the strong force can hold the nucleus together?

Explanation:

It is known that each atom consists of three sub-atomic particles which are protons, neutrons and electrons.

And, inside the nucleus of an atom, there will be only protons and neutrons. Whereas electrons revolve around the nucleus of an atom.

Protons hold a positive charge, neutrons hold no charge and electrons hold a negative charge.

As due to the like charges of protons they tend to repel each other but a force stronger than the force of repulsion helps in binding the protons and neutrons together.

This force is known as nuclear binding energy.

Therefore, we can conclude that neutrons are the other particles which is found in the nucleus and separates protons so that the strong force can hold the nucleus together.

a. they must be certified by the avma.

explanation:

mark brainliest and have a great day!

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 !
