Types of Reactions

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more substances combine to form a single product.

Front

Provide an example of a synthesis reaction using phosphorus and oxygen.

Back

P4 + 3O2 --> 2P2O3 is an example of a synthesis reaction.

Front

What does the law of conservation of mass state regarding chemical reactions?

Back

The law of conservation of mass states that the total mass of the reactants is equal to the total mass of the products in a chemical reaction.

Front

How can you identify a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation.

Front

What is a spectator ion?

Back

A spectator ion is an ion that does not participate in the actual chemical reaction but is present in the solution.

Front

Write the formula for a spectator ion in the reaction KCl (aq) + AgNO3 (aq) --> KNO3 (aq) + AgCl (s).

Back

K+ and NO3- are spectator ions in this reaction.

Front

What is the general form of a decomposition reaction?

Back

A decomposition reaction occurs when a single compound breaks down into two or more simpler products.

Front

What is an example of a decomposition reaction?

Back

An example of a decomposition reaction is 2H2O --> 2H2 + O2.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of reaction where two compounds exchange ions to form two new compounds.

Front

Provide an example of a double displacement reaction.

Back

An example of a double displacement reaction is Na2S + 2HCl --> 2NaCl + H2S.
