3. Identify the precipitate in the following reaction.
(1 Point)
K2so4(aq) + BaBr2(aq)

Acertain atom has 22 protons and 19 electrons. this atom loses an electron. the net charge on the atom is now 4+1+01-4-. if this same atom with 22 protons and 19 electrons were to gain 3 electrons, the net charge on the atom would be 3+2+02-3-.
