Look at the four chemical reactions. Reaction 1: 2H2 + O2 → 2H2O Reaction 2: 2NaCl → 2Na + Cl2 Reaction 3: CaO + H2O → Ca(OH)2 Reaction 4: 4Fe + 3O2 → 2Fe2O3 Which statement identifies the reaction that is different from the rest and explains correctly why it is different? (1 point) Reaction 2, because a single reactant is decomposed Reaction 1, because two reactants have decomposed Reaction 2, because a single ion is replaced in a compound Reaction 1, because two ions have interchanged their positions
