Balancing Equations
Chemicals equations are not always balanced, sometimes we will have to balance them …
1. Balance different types of atoms one at a time
2. Start with atoms that appear only once on each side

1. Balance different types of atoms one at a time
2. Start with atoms that appear only once on each side
3. Balance polyatomic ions that appear on both sides of the equation as a single unit
4. Balance H and O atoms last

If it’s not working…1. Deep breathe
2. Check your chemical formulas
3. NEVER change subscripts this changes the compounds!!!
4. It’s ok to start over if you get frustrated

Types of Chemical Reactions
Synthesis reaction – composition reaction – 2 or more substances combine to form a new compound
A + B AB
A and B = eles. Or cmpds.
AB = cmpd.
Example # 1: 2H2(g) + O2(g) 2H2O(g) A B AB
