Answer 1

1. Oxidation-reduction (redox) reaction: There is a change in oxidation states, where Rb goes from 0 to +1 and Br goes from 0 to -1.
2. Synthesis reaction: Two or more reactants combine to form a single product.
3. Single-displacement reaction: Rb replaces Br in the reaction to create a new compound.
4. Precipitation reaction: As the product formed is a solid, RbBr(s) is a precipitate in this reaction.
