Front

Define a chemical bond.

Back

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

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.

Front

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

Back

Coefficients indicate the relative amounts of reactants and products involved in a chemical reaction.

Front

What is the ideal gas law?

Back

The ideal gas law is PV=nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
