Write an essay about molecular modelling, its uses, and applications, and use a freely available modelling software from the internet and include the details of the modelling you followed, and give examples of at least three models you developed. The paper must be at least 1500 words, double spaced, in standard fonts and contains at least two references. Please follow APA format.
This converts the nitrogen in the protein to ammonia. The NH3 that formed was distilled and collected into flask containing 50.00mL of .09552 M HCL. The resulting solution was then back titrated, requiring 37.84 mL of 0.05992 M NaOH to reach the p..
Explain why the elimination reaction in acetone promotes an E2 mechanism while water promotes and E1 mechanism? Which product is more thermodynamically stable, the E or Z isomer?
If the reaction between iron (III) ion and thiocyanate ion yielded an equilibrium concentration of .15 M for each of these ions, what is the equilibrium concentration of the red iron (III)-thiocyanate complex
An electron is confined to a linear region with a length of the same orderas the diameter of an atom (about 100 pm).
a system absorbs 192 kj of heat and the surroundings do 110 kj of work on the system. what is the change in internal
A beaker with 145mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M
Ethane gas, C2H6, burns in oxygen to form carbon dioxide gas and gaseous water. At constant 1.60 kJ of heat is evolved when 79.442 grams of ethane is burned.
Write a mechanism for the formation of N-(2, 4-dinitrophenyl) aniline via nucleophilic aromatic substitution. Show all resonance forms that stabilize the intermediate in this reaction.
Suppose an additional gaseous component, e.g. helium, is pumped into the system, keeping the volume of the container fixed, until the final pressure is 100 atm. Assume that the helium does not dissolve in water but remains pure. Assume water is in..
What is the minimum pressure (in torr) that must be applied across the semipermeable membrane to obtain water? Assume room temperature or about 298 K.
How many different aldols (b-hydroxyaldehydes), including constitutional isomers and stereoisomers, are formed upon treatment of butanal with base?
A Cu/Cu^2+ concentration cell has a voltage of .24V at 25 degrees C. The concentration of Cu^2+ in one of the half-cells is 1.5*10^-3 M. What is the concentration of Cu^2+ in the other half-cell
