Consider the reaction 2A + 3B ⟶3C + 2D. The standard enthalpy of formation for A, B, C and D are -79.8, 49.2, -145.8, and -87.4, respectively in kJ / mol. What is the standard enthalpy change for the reaction in kJ/mol?

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
