MHS Unit 8 Test Review

Front

What is a Single Replacement reaction?

Back

A reaction where one element replaces another in a compound. Example: Na + CaF2 -> Ca + NaF.

Front

What is a Synthesis reaction?

Back

A reaction where two or more substances combine to form a single product. Example: 4Si + S8 -> 2Si2S4.

Front

What is the purpose of balancing chemical equations?

Back

To ensure that the number of atoms for each element is the same on both sides of the equation, following the Law of Conservation of Mass.

Front

How do you balance the equation: RbNO3 + BeF2 -> Be(NO3)2 + RbF?

Back

The balanced equation is 2 RbNO3 + 1 BeF2 -> 1 Be(NO3)2 + 2 RbF.

Front

What is a catalyst?

Back

A substance that increases the rate of a reaction without being consumed in the process.

Front

What is a Decomposition reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: 2H2O -> 2H2 + O2.

Front

What is a Double Replacement reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds. Example: AgNO3 + NaCl -> AgCl + NaNO3.

Front

What is a Reactant?

Back

A substance that undergoes a chemical change in a reaction.

Front

What is a Product?

Back

A substance that is formed as a result of a chemical reaction.

Front

What is the Law of Conservation of Mass?

Back

Mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.
