a) Find the balance reaction and the corresponding E for the oxidation of Fe+2 by dissolved oxygen, O2
b) If water is in equilibrium with the atmosphere with respect to O2 (i.e., PO2=0.21) and pH=7, [Fe+3]= 10-4, and [Fe+2]= 10-7, is the reaction at equilibrium?
Ozone is an air pollutant produced when nitrogen dioxide, NO2 , from automobile exhaust reactswith oxygen. The chemical equation for this reaction is NO2(g) + o2(g) ---> NO(g) + O3(g).
What is the pH of a solution that is 0.75M in sodium acetate and 0.5M in acetic acid (Ka for acetic acid is 1.85 * 10^-5
If the final temperature of the combined liquids is 28.5°C and the heat capacity of the calorimeter is 19.3 J/°C, determine the specific heat of methanol.
The total volume of seawater is 1.5X10^21 L. Assume that seawater contains 3.1 percent sodium chloride by mass that its density 1s 1.03 g/mL. Calculate the total mass of sodium chloride.
what is the molecular geometry around each central atom: CH2CH2(double bond) C=? C=? Also, for CH3 O CH3 C-O-C C=? O=? C=.
After filtering off this precipitate, the pH is adjusted to 8 and H2S is again added; no precipitate forms. No precipitate forms upon addition of (NH4)2HPO4. The remaining solution shows a yellow color in a flame test. Based on these observations,..
A steel cylinder with nitrogen, hydrogen, and ammonia gases is at 500°C and 4.91 atm. If the partial pressure of nitrogen is 1850 mmHg and hydrogen is 1150 mmHg
Suppose that 2.00mL of isopently alcohol was reacted with excess acetic acid and that 2.00g of isopentyl acetate was obtained as product. Calculate the percentage yield.
For a hydrogen atom with its electron in the 3p_z orbital, what is the longest wavelength of light that can ionize the atom?
a 2.53g of solid NaOH is dissolved in 100g of water in a coffee cup calorimeter, all the reagents initially being at 20 degrees Celsius. Calculate the final temperature of the solution obtained, given the fallowing information
The electron in the n = 5 level of a hydrogen atom emits a photon with a wavelength of 1280 nm. To what energy level does the electron move?
Given that translational and rotational degrees of freedom typically behave classically, but vibrations behave quantum mechanically, the total (avg) energy of a diatomic is predicted to be U= (5/2)RT+ , where is obtained from Eq.124.
