Does FADH2 have a thermodynamic tendency to reduce coenzyme Q at pH 7? Explain why.
what is the global pH change incurred after injection of the HCl? What would the pH change be if this same amount of 1.000 M HCl were put into a gallon of pure water?
If the solution has the same density and specific heat as water, what is ?H for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.
Calculate the enthalpy and entropy change of C2H6 from a state at 300K and 30 bar to a state at 400 K
When Lewis and Clark came through this area in the early 1800s they were forced to portage around the "Great Falls of the Missouri".
Given that the present flux of anthropogenic Na+ into the oceans is 3.39 x 1012 mol yr-1, how long would it take to increase the concentration of Na+
An average home in Colorado requires 20. GJ of heat per month. How many grams of natural gas (methane) must be burned to supply this energy. CH4(g) + 2O2(g) ? CO2(g) + 2H2O(l) ?H°rxn= -890.4 kJ/mol
The vapor pressure of a solution containing 5.40 g of a nonvolatilesubstance in 90 g water is 23.32 torr. What is the molar mass of the solute?
0.05 mL sample of 0.436 M NH4NO3 is diluted with water to a total volume of 250.0 mL. What is the ammonium nitrate concentration in the resulting solution?
Draw the structure of the one alkene which upon treatment with O2 followed by Zn and acid, would give rise to formaldehyde and cyclohexanone
You collected a water sample from your shower containing 3.2mM Ca2+ and 1.1 mM Mg2+ whats the hardness of water in terms of CaCO3/L.
In the temperature range from 40 K to 90 K, a certain amount of liquid has a temperature dependent heat capacity that is given by Cp = 18.5 J K?1 + T × 0.24 J K?2. Determine the enthalpy change resulting from heating this sample from 58.0 K to 72...
