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: CH4 + 2O2 -> CO2 + 2H2O.

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. Example: NaCl + KOH -> KCl + NaOH.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex substance. Example: 2H2 + O2 -> 2H2O.

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: 2H2O -> 2H2 + O2.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound. Example: Zn + CuSO4 -> ZnSO4 + Cu.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms for each element is the same on both sides of the equation.

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 the general form of a combustion reaction?

Back

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

Front

What are the products of a complete combustion of a hydrocarbon?

Back

The products of complete combustion of a hydrocarbon are carbon dioxide (CO2) and water (H2O).

Front

What is the difference between complete and incomplete combustion?

Back

Complete combustion occurs with sufficient oxygen, producing CO2 and H2O, while incomplete combustion occurs with limited oxygen, producing CO, soot, or other hydrocarbons.
