The Bradford assay is often utilized in place of the standard Biuret assay. Explain the general chemical mechanism of the Bradford assay as well as list the major advantages of this technique.
Reaction: 2NO(g)+2H2(g)=>N2(g)+2H2O(g) Calculate the equilibirum concentration of all the gases( in class my instructor said that a method called the ICE table is useful. do you know how to do that?). b) calculate the numerical value of Kc.
What is the lead concentration of a saturated solution of lead(II) sulfate containing 0.010 molar Na2SO4
The lead contained in a 0.2000 g sample is precipitated as PbCrO4. The precipitate is filtrated, washed and re-dissolved in acid to give lead ions and dichromate.
Oxygen gas can be obtained by the thermal decomposition of mercuric oxide; 2 HgO(s) + heat ® 2 Hg(l) + O2(g) What volume in liters of oxygen gas, measured at 6.926 °C and 0.9130 atm, would be produced from 12.43 g of HgO

Calculate the sulfide ion concentration that is required to just start precipitation of CoS from a solution that is 0.10 M in Co2+. For CoS : Ksp = 4 x 10-21
given the equation 2C2H6(g)+7O2(g)->4CO2(g)+6H20(g) How many grams of oxygen are needed to react with 4.00 moles of C2H6?
A metal, M, was converted to the chloride, MCl2. Then a solution of the chloride was treated with silver nitrate to give silver chloride crystals
the anesthetic procaine hydrochloride is often used to deaden pain during dental surgery. the compound is packaged as a 10.% solution (by mass; d= 1.0 g/mL) in water. IF your dentist injects 0.50 mL of the solution, what mass of procaine hydrochlo..
A carboxylic acid can exist in two conformations E and Z that are different by the dihedral angle around the C-O bond. Recent theoretical calculations indicate that the Z conformer of formic acid
