Use an energy-level diagram to show the electron arrangement in
the scandium (Sc) atom. The atomic number of Sc is 21. Write an
allowed set of quantum numbers ( ) for the highest energy
electron.
1. Use of a demand/supply diagram to analyze the market for
energy - calculating the equilibrium quantities and prices - with
taxes and with subsidies.
Show full calculation of HCO3- calculation by balance of anion
charges and cation charges.
The anion concnetration (mg/L) that were given was:
Fluoride= 1.286
Chloride=43.014
Nitrate=12.016
Phosphate=0.513
Sulfate=113.326
And the cation concentration (mg/L) that were given was:
Sodium=47.788
Potassium=5.741
Calcium=56.796
Magnesium=17.019
Use Molecular Orbital theory to show why cyclobutadiene is
antiaromatic but the cyclopentadienyl anion is aromatic. (Hint: use
the polygon rule to predict the molecular orbital energy
diagrams).
