Any oxidation-reduction reactions can be balanced by inspection. Try to balance the following reactions by inspection. In each reaction, identify the substance reduced and the substance oxidized. (Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)C3H8(g) + O2(g) ? CO2(g) + H2O(l)Al(s) + HCl(aq) ? AlCl3(aq) + H2(g)Cu(s) + Ag^{+}(aq) ? Ag(s) + Cu2+(aq)
