Discuss the similarities and differences between competitive and noncompetitive enzyme inhibition.
Calculaw the concentration of hydroxide ions in stomach acid at body temperature. ([H3O^+]=0.10M)
Use the Henderson Hasselbalch Equation to calculate the pH after the addition of 0.10 M NaOH to this solution, assuming no change in volume?
If 7.85 x 10 to the 24th power Sc atoms react with excess CaO, how many grams of each product will form? You will need to determine the equation of the reaction.
calcutate the molecular weight of surfur if 35.5 grams of sulfur dissolve in 100 grams of CS2 to produce a solution that has a boiling point of 49.48c.
A 0.5220g sample of an unknown monoprotic acid was titrated with 9.96*10^-2 M NaOH. The equivalence point of the titration occurs at 23.84mL.
In acid-base equilibria, the strength of acids and bases are reflected by their Ka's and Kb's, respectively. Explain, using examples while Ksp cannot directly reflect the solubility of the ionic compound. When can Ksp be used to directly compare t..
Draw appropriate Lewis structure and VSEPR structure for oxalate anion. What is the O-C-O bond angle? What is the C-C-O bond angle? What is the hybridization of each carbon? On which atoms does the negative charge reside? Draw all resonance struct..
The phase diagram starts at 0K and gradually increases from 100k to 200k and as it hits 200K, the line splits apart increasing in pressure
What is the vapor pressure at 75 degrees celcius of an aqueous solution prepared by the addition of 52.9 g of urea CO(NH2)2 to 178 g of water?
A 10.0 mL sample of liquid bleach is diluted to 100. mL in a volumetric flask. A 25.0 mL aliquot of this solution is analyzed using the procedure in this experiment. If 12.1 mL of 0.30 M Na2S2O3 is needed to reach the equivalence point, what is th..
