i need help with my chemistry homework...

my teacher is apparently too stupid to actually teach us the things she tells us to do so i have no idea what to do on some of it... i am mostly stuck on the things relating to elements and such.
so... is there anybody able and willing to help me? i have until monday to get it all done and bring my grade up to a passing grade... and i kinda need my diploma.

oh, and i am in high school level icp/physics...

 

Whats the question that you need help with? I'm pretty good at chem, So I should know it.

 

I'm decent in Chemistry and PHysics. Depending on what exactly you're working on, I might be able to help

 

sorry i was off researching marie curie and i got side tracked and watched repo again...

right now i am doing chemichal bonding(i think) or balancing... the one where we use the little dots and put the elements together. i understand how to do it, but the teacher wouldn't tell me what elements had what dots and etcetera.

i will list the questions if that would help. give me a bit...

1. Li1+O2-
2. Ba2+Cl1-
3. Ba2+N3-
1, 2, and 3 are ionic.

4. CH4
5. NH3
6. CO2
4, 5, and 6 are covalent.

and thanks for the help.

 

4,5,6 are easy. Here:

They're the circled parts.
1,2,3 aren't difficult too, but I'm not sure about them and I don't want you to have mistakes made by me.
