1. What is a Chemical Reaction?
... • A chemical formula tells the composition of a compound using chemical symbols and subscripts. Example: H2O The letters represent the type of element, the #2 (subscript) indicates how many atoms of the element are in the substance. If no subscript is present, then it means there is only 1 atom of t ...
