stoichiometry

Balance tis equation:

HCl + Na2CO3 --> NaCl + H2O + CO2

C2H5OH + KMnO4 --> CH3COOH + MnCl2 (Acidic condition, use HCl)

P2O5 + H2O --> H3PO4

H2O2 + H2C2O4 --> H2 + H2O + CO2

I know what you mean about Italian teacher, unfortunately, we had it worse.

We had no physic teacher at all, then we got one for 2 hours every 2 weeks. (the other teachers were like a year9 chemistry teacher, teaching A level physics...)

The problem with him, he has the thickest Greek accent I ever heard and he spoke half the class in Greek. He would interchangeably use English and Greek and we were all sat there wondering what is going on.

I always flunked the terms when they gave questions related to stoichiometry....buuuut then I never was good with numericals and chemical reactions.........good luck to you though

seriously take history or something where you write essays, it's so much easier,

Essays are the bane of my existance, I loath essays the writing that goes into them, all the grammar, havard refrencing (hell!) biblographys... Introductions, Conclusions, logical essay structure...

Gah! I HATE ESSAYS!!

Apart from that I quite enjoy history and politics... would have been great subjects for me barring the essays...

Chemistry was a little too wordy for my liking as well...

Maths... now theres a subject!

No refrencing no logical essay structure and none of the other rubbish i hate... pages full of sums... ahh bliss...

I dropped Chemistry sometime last year...

Oh, I got bored so I completed this.

Ugh I hate maths. It's OK when it's sums and all, but when it gets advanced and they start asking me to actually think and do all this problem solving... sorry no thanks.

Essays are dead simple, same every time. What to do is make four of five good points, write them down on paper with a few bullet points of more detailed stuff on each. Sum up the five main points in the intro, same for the conclusion, and just write out your notes in between!

Thats when it gets really good!!

You do my essays and ill do your maths!

My problem with essays is probably fairly clear from the way i write, my mind is constantly a jumble of the various things related to whatever im writing on at the time... this stops my thoughts going in a coherent order and manages to obscure whatever points im trying to make...

I can of course work on it (over and over) until it is sorted and im sure i would get it right with a bit of work... but then im guessing thats the same for you with maths... just seems like hard work and isn't enjoyable compared to essay writing...
