 Translating is when I give you a word equation that you have to turn into an equation written with the formulas  Hints: Diatomic molecules are always written as H 2  Br 2, I 2, N 2, Cl 2, H 2, O 2, F 2, Words like “reacts with”, “added”, or “mixed” mean + “Produce”, “yields”, or “form” means 

 potassium bromide  potassium metal + bromine KI  K + Br 2

 calcium fluoride  calcium + fluorine CaF 2  Ca + F 2

 Hydrogen reacts with oxygen to produce water. H 2 + O 2  H 2 O

 Silicon tetrachloride decomposes into silicon and chlorine SiCl 4  Si + Cl 2
