Key Match the term on the left with its definition on the right: J Activation A. A one or two letter abbreviation for a chemical element. The first Energy letter of the chemical symbol is capitalized. I Agitate B. An expression representing a chemical reaction; the formulas of the reactants are connected by an arrow with the formulas for the products. U Catalyst C. This is reactant in a chemical reaction that limits the amount of product that can be formed. The reaction will stop when all of this reactant is consumed. D Chemical D. Energy stored in chemical bonds of molecules. Energy B Chemical E. The changing of substances to other substances by the breaking of Equation bonds in reactants and the formation of bonds in products. E Chemical F. This is the speed at which a reaction progresses. Reaction A Chemical G. Random kinetic energy possessed by objects in a material at finite Symbol temperature. An object that feels hot has a lot of this. Q Coefficient H. A chemical reaction in which two or more substances combine to form a single substance. Also known as a combination reaction. T Combustion I. To stir, shake, mix, or otherwise move something in order to accelerate a reaction or other change. O Concentration J. This is the energy needed by a system to initiate a process. V Decomposition K. This is a measure of the number of square units needed to cover Reaction the outside of a solute. L Double L. A chemical change that involves an exchange of positive ions Replacement between two compounds. Y Endothermic M. A heat releasing process. R Equilibrium N. A chemical change in which one element replaces a second element in a compound.
