Knowing that the specific heat of water is 4.184 J/g*C and the enthalpy of vaporization is 40.7 kJ/mol, calculate the energy needed to take 45.0 g of water from 25 degrees Celsius to boiling point, then boil it all away.

Someone has spilled NaOH all over the floor! Your chemistry training tells you to dilute the spill first, then neutralize it. If you started out with 750 mL of NaOH, diluted it to 1.5 L, and you need 3 L of 2.0 M HCl to neutralize, this would be the concentration of your original NaOH solution.
What is 8 M NaOH (l)?

In the Bohr model, we can calculate energy of electron transitions, and the light given off by them or absorbed by them. For the hydrogen atom, we can excite an electron to the n = 5 state (theoretically, of course), and then let it fall right back down to the n = 2 state. State the wavelength of light given off by this transition. (Hint: the Rydberg constant is 1.0973 * 10^7 1/m)
