Balancing Equations and Predicting Products

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, following the law of conservation of mass.

Front

What is the decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler products.

Front

What are the products of the decomposition of aluminum oxide (Al2O3)?

Back

Al + O2.

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 combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, producing heat and light, typically resulting in carbon dioxide and water.

Front

What are the products of a combustion reaction involving hydrocarbons?

Back

Carbon dioxide (CO2) and water (H2O).

Front

What is the general form of a single replacement reaction?

Back

A + BC → AC + B, where A replaces B in the compound BC.

Front

What is the general form of a double replacement reaction?

Back

AB + CD → AD + CB, where the anions and cations exchange partners.

Front

How do you predict the products of a reaction?

Back

By identifying the type of reaction and applying the rules for that reaction type.

Front

What is the balanced equation for the combustion of ethylene (C2H4)?

Back

C2H4 + 2 O2 → 2 CO2 + 2 H2O.
