Document Summary
The law of conservation of matter states matter cannot be created or destroyed but can change from one form to another. Atoms can be neither created nor destroyed in an ordinary chemical reaction, so there must be the same number of atoms on both sides of the equation. These numbers are found in a chemical equation: The small numbers to the lower right of chemical symbols. Subscripts represent the number of atoms of each element in the molecule. The large numbers in front of chemical formulas. Coefficients represent the number of molecules of the substance in the reaction. Check for diatomic molecules :- h2 - n2 - o2 - f2 - cl2 - br2 - i2. If these elements appear by themselves in an equation, they must be written with the subscript 2 please write these diatomic molecules on you. Chemical equations give information in two major areas.
