When purchasing an electrical device, what are the 2 financial costs you need to consider?

If a reaction has g of -136kj at 110°c, will it be spontaneous at this temperature (110°c)? yes or no

If i can still dissolve more sugar into the solution at a certain temperature what would i call that solution

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
