Front

Define Synthesis Reaction.

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: A + B → AB.

Front

Define Decomposition Reaction.

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: AB → A + B.

Front

Define Single Displacement Reaction.

Back

A single displacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: A + BC → B + AC.

Front

Define Double Displacement Reaction.

Back

A double displacement reaction is a type of chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds. Example: AB + CD → AD + CB.

What is the general formula for a Synthesis Reaction?

Back

A + B → AB

Front

What is the general formula for a Decomposition Reaction?

Back

AB → A + B

Front

What is the general formula for a Single Displacement Reaction?

Back

A + BC → B + AC

Front

What is the general formula for a Double Displacement Reaction?

Back

AB + CD → AD + CB

How many atoms of an element are in a compound represented by a chemical formula?

Back

Count the subscript of the element in the formula. If no subscript is present, it is assumed to be 1.
