Chemical Equations

Chemical reactions change chemicals from one form to another. The arrow signifies this change from the initial state on the left and to the final state on the right.

Reactants - chemicals on the left side represent the initial state, or raw ingredients.

Products - chemicals on the right side represent the final state, or what is made.

Reaction arrow - separates the products and reactants, and can be interpreted as a "yields" or "produces" or "makes", etc.

Chemical Formula - chemical composition of the compound.

Subscripts - number of each atom.

Coefficients - Number of molecules.
