Hmmmm. that is far from right. Heatgained= mass*specificheat*change in temp change in temp= heatgaind/(specificheat*mass) change in temp= 125cal/(.0920cal/gC * 60g) = 33.6 check that chaknge in temp= finaltemp-initial temp so final temp= 33.6+20 C

If you integrate the rate, you get temp. Temp= INT (15/13 t^2 -7t)dt You know temp at 1 min is 18.6C. Solve for the constant of integration. Then, you can find the temp after ten min.

chemistry
it isn't necessary to change the mass in grams to moles. the equation reads out q=s*m*(final temp - initial temp) where q is the change in enthalpy, s is specific heat, and m is mass.

It would depend on the temp of recrystallizaton. If one used a temp above the mp of fluorenol, the solute would not crystalize, but come out as a liquid. It is above the bp.

math (urgent!)
I agree with a = 5.9 d = 32.9 - 5.9 = 27 , you had that so forget the phase shift for the time being. testing your equation: t(t) = 5.9 sin (π/12t) + 27 32.9 = 5.9sin(π/12t) + 27 sin(12t/π) = (32.9-27)/5.9 = 1 12t/π = π/2 t = (π/2)(12/π) = 6 ...

chemistry
While researching energy values of fuels, a chemist designed an experiment to find out the heat of combustion of pentane. Using the known hexane heat of combustion of hexane = 4650kJ/mol and the data below calculate the heat of combustion of pentane. Set up= copper beaker 42....
