a) For your cereal sample, you added the same volume of sodium acetate that you added to your standards and solution unknown. b) You forgot to add hydroxylamine hydrochloride when you prepared the standards, but you added it when you did the cereal analysis. For part b, include a sketch of a Beer's Law plot to explainhow the error would affect the calibration line and the wt% Fe determined for the cereal. (Onthe sketch, use a solid line to represent the correct calibration line and a dotted line for the line with the systematic error.) Also discuss the advantages and disadvantages of spectral methods of analysis
Determine the average atomic mass of boron is the natural abundance of 10B weighing exactly 10.0129 amu is 80.1% and the natural abundance of 11B weighing exactly 11.0093 amu is 19.9%.
If someone can go in depth into finding the Ka to this and then guiding me through the rest of the steps, I'd be eternally grateful
If a buffer solution is 0.440 M in a weak acid (Ka = 1.0 × 10-6) and 0.230 M in its conjugate base, what is the pH?
If 2.50 L N2 react with 7.00 L H2, what is the theoretical yield (in liters) of NH3? Assume that the volumes of reactants and products are measured at the same temperature and pressure.
A quantity of N2 is kept in a 12.8 L contianer at a temperature of 42 C and at pressure of 4.7 atm. how many grams of N2 are in the container?
