CAPITAL LETTERS
mul,tiplied to the number of atoms in a speicifcchemical formula
COEFFICIENT
no of atoms present in the specific element before the number
SUBSCRIPTS
no subscript
ONE ATOM
a process in which one or more substances are converted into one or more different substances
CHEMICAL REACTION
where a material is transformed into a new one processing a new composition
CHEMICAL REACTION
chemical reaction are represented by/
CHEMICAL EQUATION
subtances before reaction and rewritten on the left side of the chemical equation
REACTANTS
substances resulting from the reaction and are presented to the right side of chemical reaction
PRODUCTS
substances are added or mixed
+
designates the reactants or products are in solid form
S
designates the reactants or products in liquid form
L
