Problem- Five expanded structures: lysine, arginine, glutathione, glu-gly-met-leu, and arg-thr. (every amino group is protonated and every carboxyl group is deprotonated)
Determine which spots in the gel are associated with each of the five substances. Use the five structures from above as your five substances.
Assume that none of the peptide bonds were broken in the electrophoresis experiment. Use lanes 1-7 only ignoring lane 8.
Please illustrate work and walk me during the problem so that I can follow and understand it.
It takes 24.0 min for the concentration of a reaction in a first- order reaction to drop from 0.35M to 0.25 at 25 degree celsious. How long will it take for the reaction to be 80% complete
Question- Calculate the pH of a buffer solution of 0.35 M acetic acid and 0.20 M sodium acetate before and after 0.0030 moles of NaOH are added to 0.100 L of the buffer
Explain the wavelengths of several photons are provided below. Explain which photon has the largest energy
Methane and hydrogen sulfide form when hydrogen reacts with carbon disulfide. Identify the excess reagant and calucate how much remains after 36 L of H2 reacts with 12 L of CS2.
potassium weighing 3.91 grams was carefully placed in a 1 liter beaker filled with water. all of the potassium reacted
Problem- Arrange the following alkaline-earth metals in order of increasing solubility in water and explain your reasoning: Ba(IO3)2, Ca(IO3)2, Sr(IO3)2, Mg(IO3)2.
The nickel-cadmium battery cell has a standard potential of +1.20 V. The cell reaction is: 2 NiO(OH)(s) + Cd(s) + H2O(l) --> 2Ni(OH)2(s) + Cd(OH)2(s) What is the standard free energy change for this reaction
For the following battery: Cd(s) | CdCl2(aq) || Cl-(aq) | Cl2(l) | C(s) Write the reduction half-reaction occuring at the C(s) electrode. (Include physical states of reactants and products.) From which electrode will electrons flow from the batter..
the standard reduction potential for the cu2+/cu redox couple is +.34V; that for h2o/H2, OH- at a ph of 7 is -.41V. For the electrolysis of a neutral 1.0M CuSo4 solution, write the equation for the half reaction occuring at the cathode at standard..
A sample of pure silver jewelry has mass of 63.3g and is heated to a temperature of 111.4C. It is placed into a container of water at 17C.
The solution was boiled to remove CO2, following which the excess HClO4 was back-titrated with 10.12ml of dilute NaOH. In a separate experiment, it was established that 27.43 ml of HClO4 neutralized the NaOH in a 25ml portion. Calculate the molari..
at 84 degrees C the total vapor pressure of a solution contains 1.2 moles A and 2.3 moles B is 331 mmHg. Upon the addition of another mole of B to the solution, the vapor pressure increasing to 347mmHg.
