For the acids, use the formula ph=-log[H⁺]. (because HCI has 1H⁺ ion per formula unit, [H⁺] equals the molarity.) For water, use what you know about the pH of neutral solutions. For the bases, examine and extend the pattern on edge

what are the choices?

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

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
