Use the atomic radius (70 pm) and density of neon at 25 °C and 1 atm (0.90 g/mL) to calculate the average density of a neon atom.
As we discussed in class, we are not necessarily limited to using a minimal basis set. We may write the molecular orbitals as a linear combination of as many atomic orbitals as we wish.
The element is so highly unstable that no observations of its properties have been possible. Based on its position in the periodic table, propose two different reasonable valence electron configurat
Write an orbital diagram for the ground state of the Calcium atom. Is this atomic substance diamagnetic or paramagnetic
The vapor pressure of acetone is 1 torr at -59, 10 torr at -31, 100 torr at 8, 400 torr at 40, and 760 torr at 56. What is the normal boiling point of acetone

It is then analyzed on the ICP. The ICP results show the liquid to be 64.8 PPM Na and 43.7 PPM P. What does this reveal about the original dry powder
What alkene (including cis and trans isomers) would be produced by the dehydration of the following alcohols? Where possible, predict the relative amounts of each product according to Zaitsev's rule
The compound is involved in the citric acid cycle for energy production within the cell. However, the compound is unstable and slowly decomposes spontaneously. Draw the decomposition products.
