A 75 kg human is exposed to 32.8 rad of radiation. How much energy is absorbed by the person's body? Compare this energy to the amount of energy absorbed by the person's body if they jumped from a chair to the floor (assume that the chair is 0.50 m from the ground and that all of the energy from the fall is absorbed by the person).
What weight of glycine pKa1 = 2.4 pKa2 = 9.6 and what volume of 1M HCl are required to make a 100ml of 0.3M buffer pH 2.4? What weight of glycine and what volume of 1M NaOH are required to make 100ml of 0.3M buffer, pH 9.3?
The liquid vaporizes quickly to gaseous nitrogen (which has a density of 1.15 g/mL at room temperature and atmospheric pressure) when the liquid is removed from the tank.
We're doing the lab Synthesis as well as Characterization of Mo2 (O2CCH3)4 and K4Mo2Cl8: Compounds that contain metal-metal quadruple bonds. Mo(CO)6 is volatile as well as air-stable. It will sublime under the reaction conditions for this experime..
