| Term | Definition |
|---|---|
| Chemical bonds | A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds |
| Reactants | A substance that takes part in and undergoes change during a reaction. |
| Products | In chemistry, a product is a substance that is formed as the result of a chemical reaction |
| Chemical equation | A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side |
| Chemical formulas | A chemical formula showing the ratio of elements in a compound rather than the total number of atoms. structural formula. |
| H2O | Each water molecule is made of two hydrogen. atoms and one oxygen atom, thus there are two "H" atoms and one. "O" |
| Law of Conservation of Mass | According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. |
| Chemical Reaction | Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products |
| Combustion | A combustion reaction (commonly known as burning ) is an exothermic reaction in which something reacts with oxygen |
| Pollutants | Pollutants can be artificial substances, such as pesticides and PCBs, or naturally occurring substances, such as oil or carbon dioxide, that occur in harmful concentrations in a given environment |
| Photosynthesis | The process in which green plants use energy from the sun to transform water, carbon dioxide, and minerals into oxygen and organic compounds. ... Carbon dioxide is absorbed into openings in the leaves called stomata |
| Respiration | The sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off |
| Limiting Factor | A limiting factor, also known as a limiting reactant or limiting reagent, is the reactant that is used up first in a reaction and therefore limits the amount of product that can be formed. |
