What is the maximum number of phases that can be in mutual equilibrium in a two-component system?
The professor's reasoning is good, because the color red is causing drivers of red cars to drive much faster than drivers of cars with other colors
Formic acid (HCO2H, Ka=1.8X10^-4) is the principal component in the venom of stinging ants. What is the molarity of a formic acid solution if 25.00 mL of the formic acid solution requires 29.80 mL of 0.0567 M NaOH to reach the equivalence point
Write out the Michaelis-Menten model for an enzyme catalyzed reaction. State at least two assumptions that must be made for enzymes that follow the Michaelis-Menten model.
If water at the boiling point is saturated with potassium hydrogen tartate, 30 mL of the solution requires 49.5 mL of 0.2 M NaOH in a titration. What is the KSP of potassium hydrogen tartate at this temperature and what is the solubility in g/L.
You are to prepare buffers at pH = 2.8, 4.5, and 7.5. In the 2nd column write the fomulas for the respective weak acid-conjugate base buffer system that is the best choice for each pH from the listed acids
What is the freezing point of a solution made by mixing 1.40 mol sodium sulfate, Na2(SO4), 1750 g H2O? (Kfp=1.86 C/m)
calculate the solubilities (g A/100 gS) at 10.2 degrees C and 0 degrees C and the mass of solid crystals in the breaker at 0 degrees C. and if you have the time, I'd really appreciate help with:
