reaction 4: 2KCIO3 ▾3 —> 2KCI + 3O ▾2

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

A.) Reaction 2, because two ions are interchanged
B.) Reaction 2, because two products are formed
C.) Reaction 1, because a single product is formed
D.) Reaction 1, because a single ion is replaced in a compound

Reaction 1 is the one that is different because there is only one product (option C).

In a reaction, there are two main components:

  • The reactants: Substances at the beginning of the reaction.
  • The products: Substances at the end of the reaction.

Moreover, a reaction can include two or more reactants as well as two or more products depending on the substances involved. Let's analyze reaction 1:

  • Reaction 1: 4Na + O2 → 2Na2O
  • Reactants: 4Na and O2
  • Product: 2Na2O

This means in this reaction there is only one product. This does not occur in reactions 2, 3, and 4 because in these there are two products.
