Front

What is a chemical reaction?

Back

A process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

Front

In the reaction KOH + H3PO4 -> K3PO4 + H2O, what is the role of water?

Back

Water is a product of the reaction.

Front

Identify the type of reaction: CH4 + O2 -> H2O + CO2.

Back

Combustion reaction.

Front

What happens in a single replacement reaction?

Back

One element replaces another element in a compound.

Front

Identify the type of reaction: Si + S8 -> Si2S4.

Back

Synthesis (combination) reaction.

Front

What is a decomposition reaction?

Back

A reaction where a single compound breaks down into two or more simpler products.

Front

In a double replacement reaction, what occurs?

Back

The ions of two compounds exchange places in an aqueous solution to form two new compounds.

Front

What is the general form of a combustion reaction?

Back

A hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Front

What is an example of a synthesis reaction?

Back

2H2 + O2 -> 2H2O (Hydrogen gas combines with oxygen gas to form water).
