Types of Chemical Reactions

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: 2 NaBr + Ca(OH)2 → CaBr2 + 2 NaOH.

Front

What is a synthesis (or combination) reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: 2 NH3 + H2SO4 → (NH4)2SO4.

Front

What is the definition of mass number?

Back

The mass number is defined as the total number of protons and neutrons in an atom's nucleus.

Front

How many electrons are in an atom with an atomic number of 50?

Back

An atom with an atomic number of 50 has 50 electrons.

Front

What is the product side of a chemical equation?

Back

The product side of a chemical equation is the right side, which shows the substances formed as a result of the reaction.

Front

What is a 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: 2 H2O → 2 H2 + O2.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of chemical reaction where one element displaces another in a compound. Example: Zn + 2 HCl → ZnCl2 + H2.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What are products in a chemical reaction?

Back

Products are the substances formed as a result of a chemical reaction.
