LMAO! Mark, thats not even funny. :hugesmile: You know I'm really bad at Science.

I thought you were taking physicociolqOF what ever it is.

Psychology :hugesmile: And I used to take Biology.

And I did a quantum physics paper today.
HOWEVER, I did fail it. :mad: Lmao.

PMSL! That's so scientific.

I don't even know what it means, pmsl. It's something to do with unseen molecular activity or something. Gah.

ah right thanks lauren
and well done sophie

2 C2H6 + 7 O2 --> 4 CO2 + 6 H2O

Showoff :whistle:

Haha, just kidding.

Right O.K im going to check if this is right cos if it is. Your a genious. lol. .:.bows down.:.

Ill wait til my chemisrt book is marked, i handed it in today. Cant remeber what the hell i put for the answer.

Haven't done it in years seems it doesn't go away.

I did a degree in Chemistry and worked in the field for abut a year, but I have been working computing ever since.

Could you explain how you do it for me? if its not too much trouble.

It's just balancing the numbers

left hand side

2 C2H6 + 7 O2

2 * C * 2 = 4 C's
2 * H * 6 = 12 H's
7 * O * 2 = 14 O's

so it is the same both sides:

right hand side

4 CO2 + 6 H2

4 * C = 4 C's
(4 * O * 2 = 8 O) + (6 * O = 6 O) = 14 O's
6 * H * 2 = 12 H's

Oh wow, that makes so much more sense, good explaining. Thamk you so much. :thumbs::hello:

wow thats cool RM i could never understamd chemesity

Chemistry is so hard! Although our teacher did use the wrong syllabus for one of our two years, before she was sacked! :laugh:

I just scraped a B! :shocked:

Chemistry is crap
I got an F in my exam:laugh:

Pmsl Sophie I got 7/24 in a Science test today. It was a practice so it didn't matter. But I didn't even get a grade, it's that low.

my nephew is at york uni studyin chemistry and physics

My mock exams fot the Junior Cert start this Tuesday.! :-l

Good look everyone in other parts of the UK whose exams are coming up now.

Got my last exam tomorrow :dance:

i have exams all week this week, sigh, 1 hour and 30 mins childcar one.:bawling:
