CHT235 Analytical and Structural Techniques in Chemical Biology
Knowledge- Know a range of structural and analytical techniques available to tackle problems in chemical biology.- Summarise the basic theory behind selected analytical and structural techniques.- Choose appropriate structural and analytical techniques for different problems in chemical biology.
Understanding- Evaluate the strengths and limitations of various techniques for tackling structural and analytical problems in chemical biology.- Discuss the results, and their limitations, from various structural and analytical techniques.- Activate and make connections with prior knowledge of chemical biology.
Assign oxidation numbers to all the elementals in each of the following: a)PO3^2- b)NH4^+ c)Fe(OH)2 d)HNO3 e)Cr2O7^2-
A buffer is prepared by mixing 500 mL of 1.50 M Ch3COOH with 250 mL of 1.00 M CH3COONa. What is the pH of the buffer system after the formation of 0.15 moles of OH- from a secondary reaction with the buffer. (Ka for acetic acid = 1.7 x 10^-5)
The conversion of glucose into lactic acid drives the phosphorylation of 2 moles of ADP to ATP and has a deltaG= -135 kJ/mol. What is the deltaG for the conversion of glucose into lactic acid
Osmostic pressure causes ground water to rise in a tree trunk. What is the colligative concentration required to drive water to the top of a 100 ft tree
A 250 mL sample of 0.100M sodium acetate is mixed with 5.00 mL of a 2.10M HCl solution. Calculate the pH of the resulting buffer.
Air bags are activated while a severe impact causes a steel ball to compress a spring as well as electrically ignite a detonator cap. This action causes sodium azide(NaN3) to decompose explosively according to the subsequent reaction.
Four essential factors can affect the rate of a reaction. Three of these factors can be related to the rate constant of a reaction through an equation known as the Arrhenius expression.
Which solution would increase the osmotic pressure of water the most?
Problem- Describe what is happening to an atom as it forms a cation in the gas phase. What factors determine how much energy is required to remove an electron
Find out which pKa value to use for glycine. To solve this problem, first set up a reaction table with a weak acid reacting with a strong base then utilized the Henderson-Hasselbalch equation to solve for the concentration of base (OH-).
What does this imply about the relative precision of the measurements.
Calculate the pH at the equivalence point for the titration of 0.120 M methylamine (CH3NH2) with 0.120 M HCl
