The ΔH per mole of CaCl2 is -81.0 kJ. Calculate the final temperature of an aqueous solution if 30 g of CaCl2 are added to 100 g of water at 23oC. Assume that the specific heat of the solution is the same as that of water
If UV = X+6 and UY = x - 1 Find YV. Y is the midpoint of U and V. Please show work.
ok, thank you for your help
