Balance the following in basic solution. (Omit states-of-matter from your answer. Use the lowest possible whole number coefficients.)
(a) Al(s) + Cr2O72−(aq) → Al(OH)3(s) + Cr(OH)4−(aq) (state: Oxidation reaction/ Reduction reaction/ Net equation)
(b) ClO3−(aq) + Cu(OH)2(s) → ClO4−(aq) + CuOH(s) (state: Oxidation reaction/ Reduction reaction/ Net equation)
(c) NO3−(aq) + H2(g) → NO(g) (state: Oxidation reaction/ Reduction reaction/ Net equation)
