Which of these would you expect to be soluble in the nonpolar solvent carbon disulfide, cs2?

Why doesn't heat added to water make the tempature rise above 100c

Ineed to find the answer of this question because i dont understand it

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.
