Jan 25---Balancing Equations

To balance a chemical equation,

number of atoms on the left side = the number of atoms on the right side.

Ex.

             2 ScCl + 3 F2  --  2 F3Sc + 3 Cl2

Step 1. Balance the atoms first

Step 2. Balance the whole group

Step 3. Be systematic---in order

Step 4. elemental form ( K2,Cl2)
