A chemical engineering student is testing out various liquids in her lab. She has seven substances: • Substance A: C6H14 (hexane). It is non- polar, mixing well with oil but not with water. · Substance B: H2O2 (hydrogen peroxide). It contains two O-H bonds, and does not mix with oil or hexane. · Substance C: C2H5OH (ethanol). Ethanol mixes well with water and hydrogen peroxide. • Substance D: CH3CONH2 (acetamide). It has two N-H bonds. • Substance E: CH3COOH (acetic acid). It mixes well with water, has an O-H bond, and is polar. · Substance F: (CH3)2CO (acetone). There are no O-H bonds, though it is polar. · Substance G: C2H4(NH2)2 (ethylendiamine). Multiple N-H bonds, and mixes well with some polar substances. She needs a substance that will mix well with silanol, SIH3OH, shown below. For safety reasons, she knows it cannot contain nitrogen and it must be able to do hydrogen bonding with other substances. Which substances are okay to use, according to this information?

The amount of UVA radiation hitting a surface at sea level in a lightly clouded day isabout 70W/m2. About half of that can be absorbed by the skin. A typical carbon-carbon bond requires 348 kJ/mol to break. A person lies on the beach for about 1hour without sunscreen (i.e. fully exposed to UVA radiation). Estimate the numberof C-C bonds broken in this person’s back (about 0.18 m2) over that period. Assumethat the average wavelength of UVA is 335 nm.

In a combustion chamber containing 5 L of carbon monoxide and 2.5L of oxygen is ignited at 298 K and 1 atmosphere pressure. Assuming complete combustion and no loss of gas, what will be the volume of carbon dioxide formed at 298 K and 1 atmosphere pressure?
why are some gases polar molecules? For example, SO2 is a polar molecule and a gas. CHCl3 is a polar molecule but a liquid. How come these two examples are both polar molecules but are in different states of matter?
