Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is the difference between a single replacement reaction and a double replacement reaction?

Back

In a single replacement reaction, one element replaces another in a compound. In a double replacement reaction, the ions of two compounds exchange places.

Front

What is the general formula for a combustion reaction?

Back

A combustion reaction typically involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water.

Front

What is the significance of the coefficients in a balanced chemical equation?

Back
