The atomic number is the amount of protons in a nucleus, while the mass number is the protons plus neutrons.
Atomic number: 8
Atomic mass : 8+8 = 16
Answer: Atomic mass is 16, while atomic number is 8

It is true, here is evidence to this question "<u>People are heterotrophs</u>: we eat plants or meat to stay alive. You might say, well, isn't everything a heterotroph? A lot of creatures are, including giraffes, dogs, fish, <em>horses </em>" I hope this helps you with what your doing.
The answer is: H₃PO₄.
A phosphoric acid is three protic acid, which means that in water release tree protons.
Phosphoric acid ionizes in three steps in water.
First step: H₃PO₄(aq) ⇄ H₂PO₄⁻(aq) + H⁺(aq).
Second step: H₂PO₄⁻(aq)⇄ HPO₄²⁻(aq) + H⁺(aq).
Third step: HPO₄²⁻(aq) ⇄ PO₄³⁻(aq) + H⁺(aq).
Species that are present: H₃PO₄, H₂PO₄⁻, HPO₄²⁻, PO₄³⁻ and H⁺.
A buffer can be defined as a substance that prevents the pH of a solution from changing by either releasing or absorbing H⁺ in a solution.
Buffer is a solution that can resist pH change upon the addition of an acidic or basic components and it is able to neutralize small amounts of added acid or base, pH of the solution is relatively stable.
