Question

In order for a reaction to begin, what is required?

activation energy
bubbling
ionic bonding
precipitate forming

Answer 1

The correct answer is activation energy. Activation energy is the minimum amount of energy required for a chemical reaction to occur. It is needed to break the existing bonds in the reactant molecules and initiate the formation of new bonds in the product molecules. Bubbling, ionic bonding, and precipitate forming are not necessarily required for a reaction to begin.
