Buffer capacity is a measure of a buffer solution's resistance to changes in pH as strong acid or base is added. Suppose that you have 115 115 mL of a buffer that is 0.420 0.420 M in both hydrofluoric acid ( HF ) (HF) and its conjugate base ( F − ) (F−) . Calculate the maximum volume of 0.120 0.120 M HCl HCl that can be added to the buffer before its buffering capacity is lost.

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

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
