Use the concept of Hess' Law to determine AH for the process 2X+Z given the following numbered processes: V 2 W AH1 W X + Y AH2 Z- 2Y ΔΗ3 Ε ΔΗ + ΔΗ+ ΔH: ΔΗ +2ΔΗ2-ΔΗ ΔΗ+2ΔΗ2+ ΔΗ3 ΔΗ + ΔH -ΔΗ3

Antithrombin III forms an irreversible complex with thrombin but not with prothrombin. What is the most likely reason for this difference in reactivity?

r^2=6Dt , where D is the diffusion coefficient of thediffusing object  and t is the  time that the object is allowed to diffuse. If the diffusion coefficient, D, of a small protein is 5 x 10^-10 m2 s-1, how long (on average) does ittake for the protein to diffuse  across a parasitic wasp that is 189 um long ?

Chopnde and co-workers in 2003 roported the vapor-liquid, liquid-liquid.and vapor-liquid-liquid cquilibrium for the system 2-methyl-1, 3 diaxolane (1) + water (2) system at 1 atm. They abbrovinte the namo of the former substanco by "2MD."

Give typed solution only Calculate the ML/HR (rate) Merrem 1 g (1g/50 mL of 0.9% NACL) IVBP Q 12 hours Infuse over 30 minutes. *Please show how you would work this using dimensional analysis, if possible. If not, it's fine if you show how you arrived at your answer another way*

why is there a difference between the stock solution concetration of chymotrypsin calculated from zero time y intercepts versus the stock solution label information?

Example The standard half electrode potential for Fe²+ vs SHE is 0.77 V. What is the value of Ee at T = 298K when: [Fe³+] = 0.2 mol l-1 [Fe2+] = 0.05 mol 1-1

I was trying to set this problem where the units cancel out. You are given ampicillin, with a recommended dose of 35 mg/kg , to a child with a mass of 21 kg. If stock on hand is 250 mg/ capsule, how many capsules should be given. How should I set this conversion problem up and it's also asking to express the number of capsules as an integer

For a gradient system with a gradient of 5-90% in 50 min, flow 2 mL/min, column 100 x 4.6 mm i.d., the first peak elutes at 20 min, and the last peak elutes at 50 min. Calculate k* for this system.   2. Can isocratic elution be used for this sample? If so, what is the range of k values to be expected. 3.Propose a way to shorten the gradient run time by eliminating the wait for the first peak to elute at 20 min. 4. For the original conditions of this question, change the conditions necessary to use a 150 x 4.6 mm column while maintaining the same k* value.

What is the hyperchromic effect? How is it measured? What does Tm imply?
