Front

What is a double replacement reaction?

Back

A chemical reaction where two compounds exchange ions or bonds to form different compounds.

Front

What is the significance of balancing chemical equations?

Back

It ensures that the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides of the equation.
