Question

Complete and balance the following oxidation-reduction reactions, which give the highest possible oxidation state for the oxidized atoms. (Use molecular formulas whenever possible. Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)

(a) Al(s) + CuCl2(aq)      (single displacement)

(b)Ba(s) + H2O(l)      (products are a strong base and a diatomic gas)

(c)N2(s) + O2(g)      (product is a gas)

(d)Si(s) + Cl2(g)      (product is a solid)

(e)Mg(s) + HBrO3(aq)      (displacement reaction)

(f)Na(s) + H2O(l)      (products are a strong base and a gas)

(g)In(s) + F2(g)      (the highest oxidation state is +3)

Explanation / Answer

(a) 2Al(s) + 3CuCl2(aq) 2AlCl3(aq) + 3Cu(s)    (single displacement)

(b)Ba(s) + H2O(l) Ba(OH)2(aq) + H2(g)    (products are a strong base and a diatomic gas)

(c)N2(s) + O2(g) 2NO(g)    (product is a gas)

(d) Si(s) + 2Cl2(g) SiCl4(s)    (product is a solid)

(e)Mg(s) + HBrO3(aq) Mg(BrO3)2(s) + H2(g)   (displacement reaction)

(f) 2Na(s) + 2H2O(l) 2NaOH(aq) + H2(g)     (products are a strong base and a gas)

(g) 2In(s) + 3F2(g) 2InF3(s)    (the highest oxidation state is +3)
