Why are there more earthquakes in California than Tennessee?

A. There is more plate movement in Tennessee.

B. California is breaking off to fall into the ocean.

C. There is more plate movement in California.

Apeak with a retention time of 407 s has a width at half-height (w1/2) of 7.6 s. a neighboring peak is eluted 17 s later with a w1/2 of 9.4 s. a compound that is known not to be retained was eluted in 2.5 s. the peaks are not baseline resolved. how many theoretical plates would be needed to achieve a resolution of 1.5?

Summarize possible ways in which phases of matter could combine to form a solution.
