| Chemical reaction | Process in which one or more substances are changed into new substances. |
| Acidity/Basicity | the pH of a substance when dissolved in water. |
| Chemical Change | change of one substance into a new substance. |
| Chemical Property | any characteristic of a substance, such as flammability, that indicates whether it can undergo a certain chemical change. |
| Flammability | is the ability of a substance to burn. (wood can burn, but ash and smoke cannot) |
| Reactant | in a chemical reaction, the substance that reacts |
| Product | in a chemical reaction, the new substance that is formed |
| Yield | produce or provide |
| Endothermic reaction | a chemical reaction that requires heat energy in order to proceed |
| Exothermic reaction | a chemical reaction in which energy is primarily given off in the form of heat. |
| Law of Conservation of Mass | states that the mass of all substances present before a chemical change equals the mass of all the substances remaining after the change. |
| Coefficient number | in a chemical equation that represents the number of units of each substance taking part in a chemical reaction |
| Precipitate | insoluble solid that forms during a type of reaction. |
| Reactivity | is the ability of two or more substances to combining and form one or more new substances |
| Chemical equation | a shorthand method to describe chemical reactions using chemical formulas and other symbols |
