    Can Total Alkalinity and Carbonate Concentration Determine pH?

    If given total alkalinity of a solution, and total carbonate concentration, is it possible to find the pH of that solution? Total alkalinity = [OH]- + [HCO3]- + 2 x [CO3]2- - [H]+

    Understanding the Kreb Cycle and ATP

    GTP is actually is released, which from a potential chemical energy perspective, is equivalent to ATP. The Krebs cycle reduces the electron carrier NAD+ to NADH, which is used in the electron transport chain after the Krebs cycle to create ATP. The overall process must be exergonic, or else we...

    Oxymercuration demercuration reaction help.

    Sterics is not really a factor with this type of a reaction, it is electrophillic addtion, which takes place around the planar sp2 alkene. If a carbocation were formed, a methyl shift would most likely result in the OH moving to the 3 degree carbon, however, the mercuration reaction proceeds...

    Determining compound from IR and mass spec

    Start by looking at this, as it seems that you lack some fundmental knowledge about how mass spec works. http://www.cem.msu.edu/~reusch/VirtualText/Spectrpy/MassSpec/masspec1.htm"

    Chemical Exposure: Worried About Cancer?

    You're statement is almost too idiotic to warrant a response; almost. However, here is just one example from the MSDS of THF, "Distillation or evaporation can concentrate peroxides (if present) to create an explosion hazard." Pretty useless information I would say. Makes you think twice while...

    What Is the Entropic Energy Change When Magnesium Burns in Oxygen?

    You should probably write down some reactions to help you visualize the problem.
