omg. Chem help Pleeeese :(

[Alias]

I need the condensed formula for 5 isomers of C6H14 (hexane)


its suppose to be really easy, but i dont now how to draw 5 different isomers






try typing it like this for showing me plz


eg. CH3 - CH2 - CH(up:CH3 down:none) - CH2 - CH3

 

[Alias]

nobody? ;_;

We live in the wonderful age of the internets. All you had to do was type "5 isomers of hexane" into Google and go to the second link:

Here I did it for you:

I'm not sure I did everything ok because it's been a while since my last science class .

 

[victra♥]

I love doing this kinda stuff. <3

 

[Alias]

Riciardos, i absolutly LOOOOVE you :D

thank sooo much



i'll remember you <3

 

[Alias]

heres what i was seeing, was missing one but i found it thanks to u

 

[Alias]

and lol Lixivium

i tried googling isomers and had no luck. thats funny how they have the models i needed all there xD

but its still sort of complicated in model and rici was awesome enough to show it to me like he did

 

[Tom]

i'll remember you <3

Wait.... what?

 

[brawlpro]

Listen to lixivium!

Um, I don't think those are CH3 or CH2 groups. It's just Cs with H branches. Hexane means 6 carbons total, and 14 hydrogens.

i need help on my chem hw too plz!!!!
i know the steps to balancing redox reactions, (like split em in half) but i dont know how to like split these ones....

Cl2 + H2O -> OCl- + Cl-

H2O2 + NO2- -> NO3-


yah if ne1 could help me out... im desperate!

The top one is messed up, there's no H produced...
Same with the second one actually...

They're the exact same thing, just written differently.

It's not messed up, the protons simply aren't written out.

Cl2 + H2O -> OCl- + Cl-

H2O2 + NO2- -> NO3-

First one's easy; Cl2 is being both oxidized and reduced, so the first reaction you want to look at is:

Cl2 -> OCl-
When you balance it and all, you get Cl2 + H2O -> 2OCl- + 2e- + 4H+

Next we look at:
Cl2 -> Cl-
After balancing and such, we find that it is:
Cl2 + 2e- -> 2Cl-

Adding the two together, we get for our final equation:

2Cl2+ 2H2O -> 2OCl- + 2Cl- + 4H+


Second one's a little trickier, and it's been a while since I've done a lot of hydrogen peroxide redox to be honest so I can't remember how to completely balance it.
The nitrite part is easy though:
NO2- -> NO3-
When balanced yields: H2O + NO2- -> NO3- + 2e- + 2H+

I cannot seem to get the peroxide to balance properly unfortunately. Are you sure it's H2O2 and not just H2O?



Keep the chem questions coming though!

Yup, these are right. The way you would write the condensed formula for each is as follows (starting with the one on the upper left, then going down, then looking at the ones on the right and going down):

I've also included the systematic name for each one, but those probably don't mean much to you at this point, heh.

wellz we went over it today and the teacher wuz like... since its an aqueous solution, theres like water molecules everywhere so its like


H2O2 -> H2O
then... yah the ez stuff

i wuz only confused on the first one cus of that H2O (didn't if you hadda make a half reaction for it or not)

 

[mark.]

i super aced regents chem :D
but since somebody answered it lol
