Question

If an of the following
reactions occurs spontaneously, write
the balanced net ionic equation. If not,
write no reaction&
(a)Pb + Zn2+ Pb2t+Zn
(b)Fe+HH* Fe2t+H2
(c)Cu+Agt Cu2t Ag
(d)Cr + Zn2+ Cr2++Zn

Answer 1

Explanation:

Balanced equations are those whose coefficients result in equal numbers of atoms for each element in the reactants and products. Chemical reactions in aqueous solution that involve ionic reactants or products may be represented more realistically by complete ionic equations and, more succinctly, by net ionic equations.
