Chemistry - November 2006

i am having problems finding appearance details about the element carbon. i really need this! i cant seem to find anything about its appearance except that when it creates carbon it is black and when it is diamond it is colorless! so, if i were to have a pure sample of carbon, what would be some characteristics i could notice??


thanks!

I need help on the Net Ionic equation for Alum. The equation is:

2Al(s) + 2KOH(aq) + 6H2O(l) --> 2Al(OH)4-(aq) + 2K+(aq) + 3H2(g)

I am in AP chem and sometimes the teacher gets the problem wrong and he couldn't explain this one very well, so I decided to come here for help.

If you could also list the steps that would be really helpful.

Thanks,
Albert

Without using absolute entropy values, predict the sign of change in S° for each of the following processes.

a.) 2 NO2(g) --> N2O4(g)
b.) 2K (s) + F2 (g) --> 2KF (s)
c.) NaClO3 (s) --> Na+ (aq) + ClO3- (aq)

I'm looking for potassium cyanide in a small quantity (15 g or less). I would like to know where it's available, how much it costs, and if it can be shipped worldwide.

Are there any websites that I can get it from? Again, I'm not looking for a lot.

Also, Im looking to get some hydrochloric acid.
