Explanation / Answer

Reaction (a) is a combination reaction because the reactants combine to form a single product.

Reaction (b) is a decomposition reaction because the reactant decomposes to form two products.

Reaction (c) is a redox reaction because C is oxidized and Bi is reduced in this reaction.

Reaction (d) is a combination reaction because the reactants combine to form a single product.
