A(n) can be defined as a substance that prevents the ph of a solution from changing by either releasing or absorbing h+ in a solution

Explanation:

When an acid or base is added to a solution then any resistance by the solution in changing the pH of the solution is known as a buffer.

This is because a buffer has the ability to not get affected by the addition of small amounts of an acid or a base. As a result, it helps in maintaining the pH of the solution.

Thus, we can conclude that a buffer can be defined as a substance that prevents the pH of a solution from changing by either releasing or absorbing in a solution.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
