To break a chemical bond, particles need to collide with a certain amount of -energy -atoms -molecules -particles

-energy

Explanation:

To break a chemical bond energy is required. When a bond is broken energy is released. Activation energy is the minimum energy required to start a reaction. The lower the activation energy the faster is the rate of the reaction. Reactants collide with each other to break bonds and new bonds are then formed leading to the formation of products. Reactants must have sufficient energy to collide with each so that they can break bonds.

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
