I've got some chemistry questions to answer in order to solve a puzzle, but as my chemistry skills are ZERO, can anyone help me with the answers!

Is the puzzle

"What will the teacher say when I actually do my homework?"

Either stop sleeping in class or start doing more self study

I'm not sure how to apply a lewis diagram to get coordinates. Are they wanting you to count up the electrons then use the formula on the cache page?

nickd: I'm not sure how to apply a lewis diagram to get coordinates. Are they wanting you to count up the electrons then use the formula on the cache page?

Q1 = a+b-d-c+b-e
Q2 = most common number in answer
Q4 = a-b+c
Q5 = a+b+c+d+e
Q6 = a+c-e-b+d-a
Q7 = 1st significant figure in answer

From that I should be able to get some GPS co-ords

I realise that, what I couldn't understand was how the Lewis diagram gets turned into a number that you can add together.

At this point you know more than me, I have no clue what a lewis diagram is.

Even If I can't come up with an answer for that particular question I can figure out likely GPS co-ords by using google maps with one digit missing

All the methods of finding out all these things can easily be found on the internet.. I searched for 2 mins and found out how to work them out of the answers. You really don't have to be a chemist to work them out and as long as you have even a simple idea how atoms work getting the answers is pretty simple.

1) ON - Oxidation Number. How to work it out..

2+3.. simple maths

4) http://www.wiredchemist.com/anim-electron-dot-no3 (examples)

6) http://en.wikipedia.org/wiki/Ion
