Question

A few chem questions! Help please, will medal!

Answer 1

Fluorine is a toxic, reactive gas. Which representation (structural
formula, electron dot structure, or three-dimensional model) would
you use to explain why fluorine so reactive? Why?

Identify the bond types between the carbon and the two oxygen atoms
in the carbon dioxide molecule.

Explain why it is difficult to accurately represent ammonia two dimensionally.

Answer 2

I dont need a direct answer, just something to start me off.

Answer 3

Yeah Fluorine is reactive because it is not stable right? Fluorine to be stable it has to have 8 electrons in the outer most shell, but it has only 7 electrons ( as it is a group 7 element)
So the best way to represent this is the electron dot structure.
Structural formula and three dimensional model won't do it.

Answer 4

For the 3rd question I just answered this on somebody else's question,
It is difficult because ammonia is three dimensional and accurately representing something as 2d that is 3d is generally difficult. The fact that it has a pyramid like shape to it also adds some difficulty. It can be represented, however, using an xyz coordinate system.
I hope that made sense.

Answer 5

Oh thanks guys, LOL My computer wasnt loading.

Answer 6

No problem ^-^ I am trying to think of how to explain how to get the answer to the 2nd question...

Answer 7

CO2 right so first draw the molecule. Then you will see this O=C=O
Double bonds are the ones that are present in the molecule.

Answer 8

C has 4 valence electrons and needs 4 more. O has 6 valance electrons and needs 2 more. That means that it takes two oxygens to share with the carbon to supply the needed 4 electrons. Each oxygen shares 2 electrons with the carbon. THe result is formation of TWO bonds between each oxygen and the carbon.

Answer 9

@Rushwr Thanks so much for all the help! And Thank you @toloaf for helping out with that one problem and trying for the others! Means a lot! XD

Answer 10

No problem bubs :)

Answer 11

The carbon-Oxygen bonds in CO₂ are covalent, meaning that. they are sharing electrons. Neither Carbon or oxygen are willing to lose electrons sice they are both non-metals. So they will both try to either gain or share. Since the only way to gain is for someone else to lose, they have to both share. C has 4 valence electrons and needs 4 more. O has 6 valance electrons and needs 2 more. That means that it takes two oxygens to share with the carbon to supply the needed 4 electrons. Each oxygen shares 2 electrons with the carbon. The result is formation of TWO bonds between each oxygen and the carbon.
