Document Summary
Prevent some of the heat generated by escaping sunlight. Scientists has measured an average of . 6 degrees celsius rise since 1860. Change that only alters the state or appearance but not composition. Reactions involves chemical changes in matter resulting in new substances. Reactions involve rearrangement and exchange of atoms to produce new molecule. A chemical reaction is a written statement. States quantities, the chemical identity of the substances in the reaction, and their physical state. Molecular or ionic formulas of reactants and products. Relative numbers of reactant and product molecules that are required. Can be used to determine weights of reactants used and products that can be made. The amount of every substance used and made in a chemical reaction is related to the amounts of all the other substances in the reaction. The study of the numerical relationship between chemical quantities in a chemical reaction is called stoichiometry.
