Demonstrate hybridization of atomic orbitals for VB & MO
Correlate the molecular shape to the hybrid atomic orbitals of some central atoms.
Combine the concepts of hybrid orbitals, valence bond theory, VSEPR, resonance structures, and octet rule to describe the shapes and structures of some common molecules. I am confused on how to do these things.
Calculate the de Broglie wavelength of an neutron moving at 1% the speed of light. Calculate the velocity of a neutron with a wavelength of 75pm.
If you titrate 1.0 g of H2O2 solution (30wt%) with KMnO4, 25.05 ml of this KMnO4 solution is used. What is the molarity of KMnO4?
Problem- How much work does a gas do when is expands against a constant pressure of 0.500 atm from a volume of 50.00 ml to a volume of 350.00 ml
At a Concentration of 1M, the weak acid HN0 is 2% ionized and the pH of the solution is 1.7 . What happens when KNO2(s) is dissolved into the solution: The extent of HNO2 ionization = Increases or decreases? The concentration of H+ = Increases or ..
