Most chemical reactions can be classified as one of four types. Using the chemical equations in the Gizmo as a guide, match the following definitions to the type of reaction. One reactant is broken down into two or more products A fuel is combined with oxygen to produce carbon dioxide and water. Two or more reactants combine to form one product. Two compounds react to form two different compounds A compound reacts With an element to form a new a. Synthesis b. Decomposition c. Single replacement d. Double replacement e. Combustion

Explanation:

1. In a decomposition reaction; One reactant is broken down into two or more than two products is called decomposition.

2. A combustion reaction; A fuel is combined with oxygen to produce carbon dioxide and water, this reaction is called combustion reaction.

3. A synthesis reaction; it occurs when two or more reactants combine to form one product is known as synthesis reaction.

4. Double Replacement Reaction; Two compounds react to form two different compounds is known as double Replacement Reaction.

5.  A single replacement reaction; occurs when a compound reacts with an element to form a new compound , this reaction is called as  single replacement reaction.

b. is the answer hoped i
