a.) Draw an energy-level diagram for the valence molecular orbitals of CO. Include the relevant atomic orbitals in your diagram. Clearly label each molecular orbirals (e.g.?2, ?2p, etc) and fill in the appropriate number of electrons. Use the same energy order as the neutral O2 molecule. b.) Is CO paramagnetic or diamagnetic? What is the bond order of CO? c.) Draw a Lewis structurefor CO. Does this match the predicted bond order? d.) CO can react with OH- to form the formate ion, HCO2-. Draw the best possible Lewis structure for the formate ion. Include any non-zero formal charges and resonance if appropriate. Describe the bonding in terms of sigma and/or pi bonds, discussing the orbitals involved in bond formation, and describing any delocalization if appropriate.
When heat and a stream of H2 gas is applied to the sample, the Fe2O3 reacts to form metallic Fe and H2O(g). The Al2O3 does not react. If the sample residue weighs 2.499 g, what is the mass fraction of Fe2O3 in the original sample?
A 4.50G sample of LiCl at 25.0 degree celcius dissolves in 25.0 mL of water also at 25.0 degree celcius. The final equilibrium temperature of the resulting solution is 60.8 degree celcius. What is the enthalpy of solution of LiCl expressed in kilo..
To 1.00 L of a 0.100 M aquoeus solution of the weak base pyridine C5H5N is added 1.00 ml of 14.0 M NaOH. What fraction of the pyridine molecules in the resulting solution react with water to release hydroxide ions? (Kb C5H5N = 1.7 x 10^-9)
Find the volume of oxygen gas required to react completely with iron and Calculate the volume of oxygen gas at STP that is required to completely react with 61.0 g of iron.
When one of the atoms involved in a covalent bond has a much higher electronegativity than the other a bond results.
