A calorimeter is filled with 125 g of water at an initial temperature of 20.7 °C. A 243 g sample of solid KOH is added, and the temperature increases to 24.1 °C. Determine the quantity of heat absorbed by the water for this solution process. Determine the molar enthalpy of solution for KOH.

In this reaction n2o4(g)→2no2(g) what changes in color would you expect as pressure is increased at a constant temperature

What shape would a molecule with two bound groups and two lone pairs have?
