I don't understand this question, thanks to whoever tries to help!!
(This homework question was removed due to a copyright claim submitted by k12.com.)
heat gained by calorimeter = mass H2O x specific heat H2O x (Tfinal-Tinitial) = estimated 30100 J.
heat lost by NaAc crystals = 200 x Hf
set these equal to each other and solve for Hf. Remember it is exothermic so add a negative sign.
thanks you really helped a lot!!
