Types of Reactions and Predicting Products

Front

What is a Double Replacement Reaction?

Back

A type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. General formula: AB + CD → CB + AD.

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another element in a compound. General formula: A + BC → AC + B.

Front

What is a Decomposition Reaction?

Back

A type of chemical reaction where a single compound breaks down into two or more simpler products. General formula: AB → A + B.

Front

What is a Synthesis Reaction?

Back

A chemical reaction where two or more simple substances combine to form a more complex product. General formula: A + B → AB.

Front

What is a Combustion Reaction?

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Typically involves hydrocarbons.

Front

What does it mean for a compound to be 'Insoluble'?

Back

A compound that does not dissolve in a solvent, typically water.

Front

What does it mean for a compound to be 'Soluble'?

Back

A compound that dissolves in a solvent, typically water.

Front

What is a precipitate?

Back

A solid that forms and settles out of a liquid mixture during a chemical reaction.

Front

What is the solubility rule for sulfates?

Back

Most sulfates are soluble in water, but lead (II) sulfate, barium sulfate, and calcium sulfate are exceptions.

Front

How do you balance a chemical equation?

Back

By adjusting the coefficients of the reactants and products to ensure the same number of each type of atom on both sides.
