What is a synthesis reaction?

• Reaction in which one element takes the place of another element in the compound.

• Reaction in which a compound breaks down into two or more simpler substances.

• When two or more substances react to form a single substance.

• Reaction in which two different compounds exchange positive ions to form two new compounds.

Multiple Choice

In a synthesis reaction, the product synthesized can be either an element or a compound.

• This is a False statement

• This is a True statement.

Multiple Choice

In a synthesis reaction, the reactants may be either elements or compounds.

• This is a False statement.

• This is a True statement.

Multiple Choice

What is a decomposition reaction?

• Reaction in which one element takes the place of another element in the compound.

• Reaction in which a compound breaks down into two or more simpler substances.

• When two or more substances react to form a single substance.
