Look at the four chemical reactions. Reaction 1: 4Na + O2 → 2Na2O
Reaction 2: 2NaCl → 2Na + Cl2
Reaction 3: CaCO3 → CaO + CO2
Reaction 4: 2KClO33 → 2KCl + 3O2

Which statement identifies the reaction that is different from the rest and explains correctly why it is different?

Reaction 2, because two ions are interchanged
Reaction 2, because two products are formed
Reaction 1, because a single product is formed

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
