7. Allicin, C6H65,0, is the compound that gives garlic its odor. A sample of allicin contains 3.0 X 1021 atoms of carbon. How many hydrogen atoms does this sample contain? (A) 10 (C) 1.8 X 10^21 (B) 1.0 X 10^21 (D) 5.0 X 10^21 I know the answer is 5.0 X 10^21, but I don't know how to calculate it.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
