A 1.30 sample of dry ice is added to a 760 flask containing nitrogen gas at a temperature of 25.0 and a pressure of 715. The dry ice is allowed to sublime (convert from solid to gas) and the mixture is allowed to return to 25.0. What is the total
NiCl2 solution calculate the concentration, in moles per liter , of each of the ions present after mixing . assume that the volumes are additive.
In general, most substances melt at a higher temperature as pressure is increased (except water). Justify this behavior from your knowledge of the variation of chemical potential with pressure and complement your answer with an appropriate sketch.
