Explain the paramagnetic behaviour of oxygen on the basis of molecular orbital theory. Give reasons for a large difference in melting and boiling points between oxygen and sulphur.
Indicate the kind of hybridization (sp, sp2, sp3) you expect for each carbon atom in the following molecule. Why does each carbon atom have that hybridization?
How many grams of steam are produced. How many moles of limiting reagent remain unreacted. How many moles of excess reagent remain unreacted

The building needs about 250,000,000 lb of steam per week. Create recommendations about the size of the boiler as well as the insulation around the pipes.
Calculate the concentrations of all species in a 1.44 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4× 10-2 and Ka2 = 6.3× 10-8.
a sample is marked as containing 42.7 calcium carbonate by mass.what mass of calcium carbonate is contained in 33.9
The approximate molarity of this solution will be 0.025 M. You will take 10.0 mL of a 0.0100 M KIO3 solution, dissolve excess amounts of KI in it, and using the Na2S2O3 solution, titrate to the disappearance of the starch I2 color. Using the appro..
