Types of Chemical Reactions

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. Example: NaCl + AgNO3 → NaNO3 + AgCl.

What is the general formula for a double replacement reaction?

Back

AB + CD → CB + AD.

Front

What is a synthesis reaction?

Back

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

Front

What is a decomposition reaction?

Back

A type of chemical reaction where a compound breaks down into simpler substances. Example: AB → A + B.

Front

What is a single displacement reaction?

Back

A type of chemical reaction where one element replaces another element in a compound. Example: A + BC → AC + B.

Front

What is a chemical reaction?

Back

A process that involves the rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form.

Front

What are reactants in a chemical reaction?

Back

The starting substances that undergo change in a chemical reaction.

Front

What are products in a chemical reaction?

Back

The substances that are formed as a result of a chemical reaction.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it is conserved.

Front

What is an example of a synthesis reaction?

Back

Hydrogen gas reacts with oxygen gas to form water: 2H2 + O2 → 2H2O.
