We’re being asked to balance the given equations.
Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.
AgI + Na2S → Ag2S + NaI
Balance each of the following equations
(a) AgI + Na2S → Ag2S + NaI
(b) Na3PO4 + HCl → NaCl + H3PO4
