in a chemical reaction
(written before arrow) Arrow/yield sign ( ) -
is similar to the = sign. Product (CO2)- Substance formed after reaction Plus sign (+) - Separates the formulas
of two or more reactants or products
A chemical equation must show the same numbers
and kinds of atoms on both sides of the arrow. (Law of Conservation of Mass) Is this equation balanced?? ___H2 +____O2 ____ H2O To balance equations, you must use coefficients.
Number placed in front of a chemical formula.
Only use coefficients for balancing.
Leave subscripts alone!
Example- 2H2O. (This contains 4 hydrogen atoms and 2 oxygen atom)
