The meaning of CHEMICAL REACTION is a chemical change that occurs when two or more substances combine to form a new substance.
Common symbols in equations Reversible 1803 a scientist observed the formation of sodium carbonate crystals at the edge of a salt lake 2NaCl + CaCO3 → Na2CO3 + CaCl2. He recognized this as the reverse of the familiar reaction Na2CO3 + CaCl2→ 2NaCl + CaCO3. He reasoned that the excess ...
