Write out the chemical equations showing how a buffer solution made from H2PO4- and HPO42- would react to the addition of an acid (H+ ions) or a base (OH- ions). Why is a buffer able to resist pH changes but a solution from a neutralization reaction cannot?

the answer would be c

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
