11_Types of Chemical Reactions

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat. Example: C2H4 + 3O2 → 2H2O + 2CO2.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler products. Example: 2Pb(NO3)2 → 2PbO + 4NO2 + O2.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of reaction where two compounds exchange ions or bonds to form two new compounds. Example: 3KOH + H3PO4 → K3PO4 + 3H2O.

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 a 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

What is a single displacement reaction?

Back

A single displacement reaction is a type of reaction where one element replaces another in a compound. Example: Cu + 2AgNO3 → Cu(NO3)2 + 2Ag.

Front

What is the general form of a combustion reaction?

Back

The general form of a combustion reaction is: Hydrocarbon + O2 → CO2 + H2O.

Front

What is the general form of a decomposition reaction?

Back

The general form of a decomposition reaction is: AB → A + B.

Front

What is the general form of a double displacement reaction?

Back

The general form of a double displacement reaction is: AB + CD → AD + CB.

Front

What is the general form of a synthesis reaction?

Back

The general form of a synthesis reaction is: A + B → AB.
