What is a double displacement reaction?

Back

A reaction where the ions of two compounds exchange places to form two new compounds.

Front

What is the purpose of balancing chemical equations?

Back

To ensure that the number of atoms for each element is the same on both sides of the equation.

Front

What is the difference between coefficients and subscripts in a chemical formula?

Back

Coefficients indicate the number of molecules, while subscripts indicate the number of atoms in a molecule.
