construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
Then we are asked the bond order of SO^4+ (assuming that it is formed).
I have laboriously drawn out the whole thing (not attached) and the bond order appears to be 3.
This is on the presumption that total electrons would be 20 (16 for S and 4 for O^4+).
This ion would not be paramagnetic.
A mixture of 7.50 g He and 29.5 g Ne has a pressure of 750. mm Hg. What is the partial pressure of each of the gases?
Calculate the amount of energy in kilojoules needed to change 423g of water ice at -10 deg c to steam at 125 deg c . The following constants may be useful:
How long would it take for 1.50 mol of water at 100.0 degrees Celsius to be converted completely into steam if heat were added at a constant rate of 15.0 J/s.
Determine the molarity of the NaOH(sodium hydroxide) solution. In an acid-base titration, 22.13 mL of a sodium hydroxide solution are required to neutralize 24.65 mL of the potassium hydrogen phthalate solution?
A 59.0-g sample of an alloy at 93.0°C is placed into 264 g of water at 22.0°C in an insulated coffee cup. Assume that no heat is absorbed by the cup.
Calculate the pH of a solution when 0.200 moles of solid NaOH is added to 2.00 liter of 0.250 M HCl. Assume no change in volume.
Calculate w (in kJ) when 137 g iron (III) oxide (MM = 159.7 g/mol) reacts with excess carbon to produce carbon dioxide gas at 345 K:
what would be the atmospheric pressure of MTBE in Pa If this sample were at equilibrium with atmospheric MTBE? KH = 1.7 M/atm.
Synthesis of a Liquid Crystal, experiment in which added 500 mg of cholesterol to 1.5 mL of dry pyridine. Then added 1.7 mmol of benzoyl chloride and heated the mixture.
0.0010 mg of H, 0.0116 mg of C, and 0.0310 mg of O. It was also determined that the unknown compound had a molecular weight of 90.0 g/mol.
