CHEMICAL REACTIONS

CHEMICAL REACTIONS

CHEMICAL REACTIONS. Processes in which the atoms of one or more substances are rearranged to form different chemical compounds. Chemical reactions involve the breaking of chemical bonds in the reactants and the formation of new bonds in the products. Signs of chemical reactions.

Changes of Matter

Changes of Matter

Changes of Matter. Physical Change- a change that alters the appearance or form of a substance but doesn’t produce a new substance. Ex: melting a sample of gold Chemical Change/Reaction- a change in matter that produces one or more new substances.
