An article appeared in the British chemistry magazine, 'Chemistry World'
recently, entitled Periodic Change, by Eric Scerri. In it Scerri reviews the alterantive periodic tables currently available and explains the main categories of periodic systems. see his website for other titles
Another article is by Michelle Francl in the new journal 'Nature Chremistry' issue 2. This is titled 'Table Manners'. Also, Eric Scerri Selected Papers on the Periodic Table, Imperial College Press, 2009.
the question is;
in an equilibrium mixture of reactants and products at 400 degrees celsius,in a steel vessel with volume 10 dm cube,there were 2.0 mol of ammonia,5.5 mol of nitrogen and 5.0 mol 0f hydrogen.
calculate equilibrium constant at this temperature?
Hey everyone. I really only joined this forum for one, well, two reasons. Firstly, Id like to ask for help and ideas with a project im working on. It's an application that can solve equations and do conversions. (not like an ordinary calculator, though) It also can do a number of other things.. ..has a periodic table, a standard calculator, a journal, etc. My second reason was to show off what I have a little bit. Just a little, though. :]
Ok I am in AP Chemistry 2 and I have no clue what I am doing... so can someone help me with this problem??
Hexamethylenetetramine was used for the treatment of kidney and bladder infections prior to the development of modern antibiotic drugs. Combustion of 0.2897 g of this compound produced 0.5456 g of CO2 and ).2234 g of H2O. Separate nitrogen assay of a 0.3801 g sample yielded 0.1848 g of ammonia. What is the empirical formula of this compound?
