1. Write the chemical symbols for the element/polyatomic ions present. (Should only be 2 of them) 2. Look up their charges: in order to correctly write the symbols, each ion’s total charge must be EQUAL and OPPOSITE to each other!

Example: Lithium Oxide
Lithium is Li+1, Oxide is O-2: In order to for their charges to be equal, you must have 2 Lithiums for each Oxide present! Therefore, Li2O

Describe the chemical reaction based on the chemical equation below. also, explain whether the equation is balanced.
