what is the freezing point(Degrees C) of a solution prepared by dissolving 11.3g of Ca(NO3)2 ( formula weight= 164g/mol) in 115g of water?
How much heat (in kJ) is evolved in converting 1.00mol of steam at 130.0C to ice at -50.0C? The heat capacity of steam is 2.01 and of ice is 2.09 .
What would be the effect of performing your kinetics experiments at a lower temperature than the one you used?
working solution so you add five spatula tips full of salt to a large test tube and then make your working solution with only 5mL of deionized water.
