Identifying Types of Chemical Reactions

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction in which two or more reactants combine to form a single product.

Front

What is a combustion reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat.

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.

Front

What are the general characteristics of chemical reactions?

Back

Chemical reactions involve the rearrangement of atoms, the breaking and forming of bonds, and the transformation of reactants into products.

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 is an example of a double replacement reaction?

Back

An example of a double replacement reaction is the reaction between sodium chloride and silver nitrate, which produces sodium nitrate and silver chloride.

Front

What is an example of a synthesis reaction?

Back

An example of a synthesis reaction is the formation of water from hydrogen and oxygen gases: 2H2 + O2 -> 2H2O.

Front

What is an example of a combustion reaction?

Back

An example of a combustion reaction is the burning of methane: CH4 + 2O2 -> CO2 + 2H2O.

Front

What is an example of a decomposition reaction?

Back

An example of a decomposition reaction is the breakdown of calcium carbonate into calcium oxide and carbon dioxide when heated: CaCO3 -> CaO + CO2.
