I can't help you with your chemistry, but once you get into the labs it will be mmore intersting.\n\nA degree in general science will get you teaching jobs.  Take a course in teaching methods and get your teaching certificate and you'll be able to teach middle school science and lower level high school science.

get a good book\nlike the McGraw and Hill\nthats what we have in our Lab Chemistry class\nor go to the bonny eagle high school page and get the email for Helen Steele\nshe is a geneous i bet she could help you

I agree with birchardv here...........we need the rest of the problem, and you would learn a lot more if you did the homework yourself.  But do whatever floats your boat.  Add the rest of the problem and I'll get back to you.\n\nOkay Chemist, this problem is really long; if you want a good answer with plenty of steps, I'll need more room.  Email me and I'll send you the solution.

a) Ag2S\nb) SnCl4\nc) Na3N\nd) SrI2\n\nDo us a favor and pay attention during class. That way you'd know how to do these.

1.) do your own homework\n2.) this is the computer forum, not high-school chemistry.  Next time post to the right furom.

a phd student in chem looking for basic chem material on the web.\n\nright.\n\nstart here: http://www.carleton.ca/~rburk/chem1000\n\na textbook might also be useful.

Hmm. Maybe all you need is the guideline to balance it?\n\nFor beginners, this is probably the best way. After some time, you can omit the unnecessary steps.\n\nFirst, list down the number of atoms of elements present on both sides of equation: reactants vs products. In this case, 1S,4O vs 1S,3O.\n\nSecond, find a common number of atom(s) of an element on either side. Knowing that there is 1S on both sides, the reacting O2 molecule will thus have a stoichiometric coefficient of 1/2. This will ensure 3O on either side.\n\nThird, multiply throughout with 2 since since fractions are not preferred.\n\nOf course, math enthusiasts usually get the hang of this faster by looking for common factor and this method is exceptionally effective (faster) when reactions become complex.\n\nBut the best way is still, of course, to practice XD

use this site: http://www.chem.tamu.edu/class/majors/tutorialnotefiles/empirical.htm\n\nit shows a very simple way to figure it out...last year when i had chemistry i was out for a couple of  weeks, and i had to teach this to my self...this site got me an A+ on the test the day i returned back to class.
