A person is out on the beach for about 1 hour without sunscreen. The amount of UVA radiation hitting a surface at sea level on a slightly clouded day is about 80W/m². About half of that can be absorbed by the skin. Estimate the number of C-C bonds broken in this person's back (about 0.24 m²) over that period. A typical carbon-carbon bond requires 348 kJ/mol to break. Assume that the average wavelength of UVA is 335 nm.

CH.8 #8 - Please fill in the blank, cirlce your answer for thumbs up!
The crocodile, which can remain under water without breathing for up to 1 h, drowns its air-breathing prey and then dines at its leisure. An adaptation that aids the crocodile in doing so it that it can utilize virtually 100% of the O2in its blood whereas humans, for example, can extract only ~65% of the O2in their blood. Crocodile Hb does not bind BPG. However, crocodile deoxyHb preferentially binds HCO3ꟷ. How does this help crocodile obtain its dinner? Explain your answer.

Linolenic acid (Table 10.2) and stearidonic acid are omega-3 fatty acids, unsaturated fatty acids that contain the first double bond located at C3, when numbering begins at the methyl end of the chain. Predict how the melting point of stearidonic acid compares with the melting points of linolenic and stearic acids. A current avenue of research is examining the use of soybean oil enriched in stearidonic acid as a healthier alternative to vegetable oils that contain fewer degrees of unsaturation.

Methyl isocyanate, CH3 -N= C = O, is used in the industrial synthesis of a type of pesticide and herbicide known as a carbamate. As a historical note, an industrial accident in Bhopal, India, in 1984 resulted in leakage of an unknown quantity of this chemical into the air. An estimated 200,000 people were exposed to its vapors, and over 2000 of these people died. Q.) Methyl isocyanate reacts with strong acids, such as sulfuric acid, to form a cation. Will this molecule undergo protonation more readily on its oxygen or nitrogen atom? In considering contributing structures to each hybrid, do not consider structures in which more than one atom has an incomplete octet
