Hi

This is my first science subject ever, and I am having difficulties so I would love to have all the help I can get please.
My assignment is about Lewis structures and empirical formula for the following



1. The problem statement, all variables and given/known data
1.potassium iodine, 2. calcium flouride, (these two are ionic compounds)
3. sulfur chlorine ( covalent compound)

Write both an equation using Lewis structures and a balanced chemical equation for the ff reaction
1. Silicon atoms and chlorine molecules
2. Lithium atoms and bromine molecules
3. Ethylene molecules (C2H4) and chlorine molecules; the product is C2H4Cl2


2. Relevant equations



3. The attempt at a solution

You need to attempt the question and let us know where your stuck. No one will do the work on here for you. We need to understand the material. :)
