Use the graph of solubility of O2 in water versus temperature to calculate the value of Henrys law constant Kh for O2 at 8 and 33 degrees Celcius. (8C= .040 L oxygen gas/ L water AND 33C= .023 oxygen gas/ L water)
To account for the high electronegativity difference between hydrogen and fluorine, we reassign the orbital sites in HF in order to create an energy ladder that gives us a logical sequence for assigning electrons
Using the average bond dissociation enthalpies(BE) given, estimate the standard molar heat of reaction of the gas-phase reaction of hydrogen peroxide with methanol to yield formaldehyde and water:
Use the reactions below and their equilibrium constants to predict the equilibrium constant for the reaction, 2A(s) 3D(g).
discuss in detail one way in which atomic nuclear decay takes place. what is the significance of atomic nuclear decay?
What net ionic equations for the precipitation reaction or reactions that occur. What are the spectator ions in the solution
The total precipitate was dissolved in HCl + HNO3. When the solution thus formed was treated with excess NaOH followed by H2O2, a colorless solution and a reddish brown precipitate were formed. The precipitate was found to be soluble in HCl, H2SO4..
what is the common IUPAC name for a benzene ring with a single ammonia group (NH3) attached
Determine whether each of the following causes an increase or decrease in the activity of the electron transport chain. large difference in H+ concentration across the inner mitochondrial membrane
Glucose oxidation in the human body releases 6 mol of carbon dioxide per mole of glucose. How many moles of glucose are required to produce the amount of carbon dioxide
The reaction 2NO(g) + Cl2 (g) --> 2NOCl(g) is carried out in a closed vessel. If the partial pressure of {NO} is decreasing at the rate of 27 torr/min, what is the rate of change of the total pressure of the vessel?
Calculate the change in entropy (in J/K) for the following reaction at 298 K: C(s) + H2O(g) ? CO(g) + H2(g) Use entropy for graphite (diamond is too expensive).
Liquid pentane (C5H12) has a density of 0.6262 g/mL at 20°C. Find the true mass (mtrue) of pentane when the mass weighed in air is 12.580 g. Assume the air density is 0.0012 g/mL and the balance weight density is 8.4 g/mL.
