NEED HELP ASAP Calculate the equilibrium concentrations of H2, I2 and HI at 700.K if the initial concentrations are [H2] = 0.400M, [I2] = 0.400M. The equilibrium constant Kc for the reaction is 57.0 at 700K.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
