Acids
Chemical substances that are produced in a reaction.
Products
Type o reaction in which heat energy is released by forming the chemical bonds in the product.
Exothermic
Substance formed when an acid is neutralized by a base or alkali.
Salt
True or False? During a chemical reaction, no atoms are lost and no new atoms are produced.
