Cytochrome c oxidase receives electrons from reduced cytochrome c (Cyt c red) and transmits them to molecular oxygen with the formation of water.
a) Write a chemical equation for this process which occurs in an acidic environment.
b) Estimate the values of E+, delta G+ and K for the reaction at 25C
When bicarbonate is reacted with acid it releases CO2. How many moles of HCO3? did you start with if you collect 1.24 x 10 3 moles of CO2(g)?
Calculate the specific rotation of the compound. A sample of 150 mg of an organic compound is dissolved in 7.5 ml of water. The solution is paced in a 20-cm polarimeter tube and the rotation measured in a polarimeter
An aqueous solution contains 12.7% NaCl by mass. What mass of water (in grams)is contained in 2.5L of the vapor above this solution at 55 celcius? the vaor pressure of pure water at 55 celcius is 118 torr.
Calculate the solubility of carbon dioxide in water at an atmospheric pressure of 0.38 atm.Carbon Dioxide has a mole fraction of
You found that pH=pKa=4.2 when 12.50 mL of NaOH hadbeen added. The concentration of the sodium hydroxide was 0.500M. Calculate the initial percent dissociation of the acidsample.
Using the same sample of gas ( = 275 , = 43 ), we wish to change the pressure to 2750 with no accompanying change in volume or amount of gas.
Sucrose and glucose are nonvolatile. What is the mole fraction of water in this solution?
Radical formed by H-abstraction from diethyl ether. Showing curved arrows to where it goes.
A metal has crystallized with a face-centered cubic lattice. The edge of the unit cell is 366 pm. What is the diameter of the metal atom?
The solution which passed through the filter was collected in a beaker and excess sodium sulfate solution was added to this beaker. 0.432 g of fry precipitate was collected from this second solution by filtration. Calculate the percent of magnesiu..
A 13.386 g aliquot of this solution is then titrated with 0.1052 M HCl. It required 30.21 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
