CaCl2. I determined it by knowing the common oxidation states for calcium and chlorine.
Formula: Ca3P2
The formula is CaSiO4.
Calcium's chemical symbol is Ca. Calcium's oxidation number is +2.Chloride's chemical symbol is Cl. Chloride's oxidation number is -1.Ca +2 Cl -1Ca 1 Cl 2 (Switch the two numbers)Ca1Cl2 HOWEVER if there's only one of an element, don't write the 1CaCl2
CaSO4
CaO.

The chemical formula for calcium chloride is CaCl2 - Ca++ ionically bonded with 2 Cl-.
CaO.
