Steps to Writing ReactionsSteps to Writing Reactions• Some steps for doing reactions
1. Identify the type of reaction2. Predict the product(s) using the type of
reaction as a model3. Balance it
Don’t forget about the diatomic elements! (HI BrONClF) For example, Oxygen is O2 as an
element.
In a compound, it can’t be a diatomic element because it’s not an element anymore, it’s a compound!
