– Chemical equations - • The conversion of reactants into products.

Reactants - the molecules shown on the left of the arrow. Products - the molecules shown on the right of the arrow.

• sign separates molecules on the same side

• “yields”

–ExampleC + O2 CO2

• You would read this as:– “carbon plus oxygen react to yield carbon dioxide”

Parts of a Reaction Equation

Page 4: Balancing Act. Atoms are not created or destroyed during a chemical reaction. Na F Mg Li O.

Scientists know that there must be the same number of atoms on

each side of the equation.(Law of Conservation of Mass)

To balance an equation…you must add coefficients in front of the chemical formulas. You can not add or change

subscripts.

_H + _Fe 2HFe

Changing the subscripts changes the compound. • Subscripts are determined by the valence

electrons o (charges for ionic or sharing for covalent)
