# Thread: Chemistry quiz tomorrow/test on thursday (stoichiometry) misc help me pls!!! :'(

1. ## Chemistry quiz tomorrow/test on thursday (stoichiometry) misc help me pls!!! :'(

get sick, dont go to class for 2 days and i dun goof :/
brb so behind
brb what the hell is going on
brb this is gibberish to me
brb giving up on med school

so i need to learn stoichometry crap from start to finish for my quiz tomorrow/test on thursday.
what do? where should i start? rapes for life.

2. balancing reactions. Then just follow the textbook

3. Stoichiometry is easy.

Every chemical equation has to be balanced.
If you have 3 carbon atoms on the left side of the equation, you must have 3 carbon atoms on the right side of the equation.
If you have 7 oxygen atoms on the left side of the equation, you must 7 oxygen atoms on the right side of the equation.

See the idea?

The objective is balance both sides. so, if I gave you the following problem and told you to fill in the coefficients...
(?#)H2 + (?#)O2 -------> (?#)H2O

You have to find the proper coefficients so that the number of atoms on each side is the same. In this case, the proper answer is 2H2 + O2 ->2H2O
(4 hydrogens, 2 oxygens on each side. The equation is balanced)

4. gl brah

5. 3 options

Give up
Study 8 hours tonight all night
**** this test up and study 5 hours 3x a week from now on.

**** is easy once you understand the concept

6. you get off the misc and start studying you phucking retard.

negged for being a moron

7. If its just over introduction of stoichiometry

Think of it like solving a puzzle:

1.) Figure out what you are being asked
2.) Find out what you have (balanced chemical equation)
3.) Find out what you are missing
4.) Solve for what you are missing

If its Equilibrium reactions and such that are getting you, disregard above.

8. Cliffs:
- For every atom on the left side of an equation make sure there is the same number and same type on the right side.
- Make sure the charges on the left = the charges on the right.

Eg: SnO2(s) + 2 H2(g) → Sn(s) + 2 H2O(g)

Charge on both sides is 0. Number of atoms on both sides are equal.

I havent been on the misc, been trying to teach myself and thought i would post a thread and see if others can help me out.
why even post in this thread you negative nancy if youre not going to help. so enjoy the neg back, you beta phaggot e statting manlet.

i can see cleary now..the rain is gone, okay this part makes sense now, thanks bb

10. dude, stoichiometry is the easiest part of chem. If you have hard time with that, then all your chem prereqs for med school will be hell for you.

well the thing is i hadnt been in class due to illness ^as stated in op

12. Da fuk OP? Just read the textbook........if it was only 2 days of class material then you can learn it fairly quickly. and its stoichiometry which is the easiest fukin chemistry problems

Seriously read the fuking textbook you lazy fuk, it sounds like youre just being a lazy fuk and dont want to read and just want the quick easy route. unless you have a reason that you dont have a textbook or cant read or something.

you should be reading the textbook anyways...if you cant do stoichemetry, then quit right now, if you dont have the drive to read the textbook for STOICHIOMETRY, then you wont have a chance doing much more advanced chemistry

look for chemistry by brown, its available on some torrent sites for download. then go to stoichemotry section and study away
