Which of these equations does not represent an oxidation-reduction reaction? |
Multiple Choice
3Al + 6HCl → 3H2 + AlCl3
2NaI + Br2 → 2NaBr + I2
2H2O → 2H2 + O2
Cu(NO3)2 + Zn → Zn(NO3)2 + Cu
The options which you had given are all oxidation reduction reactions.
So i included one more reaction which does not represent oxidation reduction reaction.

Which of the reactions below does not represent a redox reaction? 2 NaI (aq) + Br2 (l) → 2 NaBr (aq) + I2 (g) 2 NaCl (aq) + Pb(NO3)2 (aq) → PbCl2 (s) + 3 NaNO3 (aq) 3 Al (s) + 6 HCl (aq) → 3 H2 (g) + AlCl3 (aq) 2 H2O (l) → 2 H2 (g) + O2 (g) None of these
Choose a chemical reaction to discuss. Give a balanced equation to represent the reaction, tell the type of chemical reaction it is and give one mole relationship for the reaction. You should have one that is combination, decomposition, single replacement, double replacement, oxidation/reduction, or combustion. Not using: 2H2 (g) + O2 (g) yields 2H2O(g) -OR - N2 + 3H2 yields 2NH3
