Balancing Chemical Equations Worksheet

Steps to follow:

1. Write the type of equation.
2. Identify all the ions involved on both side of the products and reactants.
3. Balance the following equations
4. Write the number of ions for the products and reactants.

Example:

Zn₃(PO₄)₂  +  NaCl --->  Na₃PO₄  +  ZnCl₂

Step 1.  Double Displacement

Step  2.  

• Reactants:      Zn⁺², PO₄^-3, Na⁺¹,  Cl ^-1           
• Products:      Zn ⁺²,  PO₄^-3, Na⁺¹, Cl^-1                         

Step 3.       1Zn₃(PO₄)₂  + 6NaCl --->  2Na₃PO₄  +  3ZnCl₂

Remember, You are multiplying the yellow number times the blue number.

Step 4. 

• Reactants:      Zn⁺² = 3, PO₄^-3 = 2, Na⁺¹ = 6,  Cl ^-1 = 6        
• Products:      Zn ⁺² = 3,  PO₄^-3 = 2, Na⁺¹ = 6, Cl^-1 = 6
