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!

Solve a problem, or complete a homework assignment?

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?


The additional calculations to the answers as follows

Q1 = a+b-d-c+b-e
Q2 = most common number in answer
Q3 = rounded answer
Q4 = a-b+c
Q5 = a+b+c+d+e
Q6 = a+c-e-b+d-a
Q7 = 1st significant figure in answer
Q8 = answer minus 59

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..

http://chemistry.tutorvista.com/analytical-chemistry/oxidation-number.html

2+3.. simple maths

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

5) http://en.wikipedia.org/wiki/Valence_electron

7+8 (google is your friend, I didn't look these up)

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