Balancing equations will be the death of me.

it's the easiest part of chem for me.

Quit showing off

Just cause you're rank 1 in chem

Just count up the individual atoms on each side.

Tbh, the worst thing about balancing equations was that there was no method for finding them if you are stuck other than trial and error.

So just use trial and error and you should get them after a few tries eventually.


Usually what I try to do is find a ratio of atoms on each side, and adjust everything by multiplying by the amount required to get it so that it might work, then test it afterwards to see if it works.

It's not just balancing, but also knowing how to write equations up from scratch, i.e. knowing your valencies otherwise you're screwed.

Which is why I suck at chem lol.

I only have 12 units...BUT ME HATE MATHS TOO :'( my dad won't even let me drop to general....but i think i probably should...im dying in 2u maths. I came last in 3u maths fot half yearly so i dropped it.. May as well drop to gen maths....or drop it all together ^.^ :3

Why do you hate maths?

 

[rawrliongirl]

Lol i just walked home from my bus stop which is about 1km away from home..and my neighbours were also walking home, except i dont think they realise im their neighbour cos i look way different from when they last saw me (which was a very very very long time ago since we all keep to ourselves and stuff).. And i think that they must've thought i was stalking them or something :')

 

[rawrliongirl]

I could never do it. As in never understand it. Even with tutoring its still confusing..and heaps time consuming, i could be doing better things with that time i waste on maths.

Yah that is the part where you need to rote learn.

Knowing those helps a lot ..: I did pre bad in Chem... Ended up with a 66

I've been trying to derive from the periodic table and it only works half the time so yeah, rote learning may be the way to go for valencies.

I think imma drop society's and culture

dude all you need to do balance equations is to know how to multiply, add, subtract and divide and memorise a few valancies or polyatomics.

wth are polyatomics?

 

[justem]

wth are polyatomics?

Polyatomic ions like NO3, NH4

I meant polyatomic ions like ammonium, sulfate, hydroxide etc..

oh fk those are a pain in the ass to remember

if you want full marks then only practice makes perfect (so cheesy)

Hun, you should do what you think is right. If your parents don't allow it you have to convince them - it's your education, your life and your future. Choose what you enjoy and do what upholds your sense of self and morals and that goes with everything. I hope you'll be able to overcome it good luck!!

You've certainly come a long way since haha

 

[rawrliongirl]

There's no way my dad would sign my form to drop to general maths :'( maybe if i show him that I AM FAILING and fail my yearly he will let me...it worked to drop extension maths..
