What best describes the function of a centrifuge?

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.

The appropriate concentration for an iodine sanitizer is

Reactions in cells take place at about a. 40°c b. 0° c. 100°c d. 60°c
