Physics
Heat lost by spoon = heat gained by water Use that heat, the aluminum temperature drop, and the specific heat of aluminum to get the mass. Ignore the styrafoam mass. It acts as an insulator to keep the heat inside, and weighs very little.

The ksp of aluminum hydroxide is 5.6e-17. What is the concentration of hydroxide in a saturated solution? For the answer I got [AlOH] <=> [Al] [OH]^2 5.6e-17 x 3x 5.6e-17 = 3x^4 x = 6.6e-5 Is this right? I'm not sure about 3x^4 part...
