The Yellowstone Caldera is a crater in Yellowstone National Park that sits on top of a hot spot and an active magma chamber. The Yellowstone Caldera and other calderas in the park were formed by volcanic eruptions from the same hot spot. Based on this information, which statement about the Yellowstone Caldera is true? A.
The Yellowstone Caldera is the only caldera in the park resulting from a meteorite strike.
B.
The Yellowstone Caldera drags the hot spot with it when the plate beneath the caldera moves.
C.
The Yellowstone Caldera will eventually move farther away from the hot spot source.
D.
All the calderas in the park, including the Yellowstone caldera, formed at the same time.

Both 1,2−dihydronaphthalene and 1,4−dihydronaphthalene may be selectively hydrogenated to 1,2,3,4−tetrahydronaphthalene. one of these isomers has a heat of hydrogenation of 101 kj/mol (24.1 kcal/mol), and the heat of hydrogenation of the other is 113 kj/mol (27.1 kcal/mol). match the heat of hydrogenation with the appropriate dihydronaphthalene.

Dying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this. a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers? the work is not scientific because the data are not processed in one location. the work is not scientific because the simulations are not reproducible. the researchers applied creativity to solve a problem in running an experiment. the researchers used only well-established scientific techniques.

Consider the following system at equilibrium. caco3(s) ca2+(aq) + co32–(aq) the addition of which compound will cause a shift in equilibrium because of a common ion effect? ccl4 co2 cuso4 na2co3
