Given the following information, calculate the different heat steps and graph the phase transition Heat profile using Excel going from 0 to 400 K for 1 mole of the compound.
FW = 40 g/mole Specific heat for solid is 1.34 J/g K, for liquid 4.21 J/g K, and for gas 7.43 J/g K
Boiling Point is 56 oC and Melting point -23oC
Latent Heat of Evaporation is 36.4 kJ/mole
Latent Heat of Fusion is 30.3 KJ/mole
A saturated solution of BaF2 at 25 degrees Celsius was prepared by equilibrating solid BaF2 with .5 L of water Ksp of BaF2 is 1.7 x10-6 at the temperature. A) Compute the mass of BaF2 that dissolved.
How do you get the specific heat capacity of an unknown metal. This is the enthalpy and specific heat lab.
A piece of the mineral zircon is found to contain a Pb-206:U-238 ratio of 0.213 g:1.00 g. Assuming all Pb-206 in the sample is attributable to decay of U-236
A glucose molecule is labeled at carbon-3 with 13C. How many turns of the citric acid cycle are required to remove the carbon as CO2?
Calculate the pH during the titration of 24.8 mL of 0.793 M HBr(aq) with 0.219 M KOH(aq) after 14.1 mL of the base have been added.
Tween-20 is a detergent that is often used in immunological assays. Concentrated Tween-20 a viscous liquid and is difficult to accurately pipette in small amounts. Because of thism it is common to make a 10% stock of Tween 20 i nwater and use this..
Compare the stability of two conjugated dienes, and two nonconjugated dienes, each with the formula C7H12 and the base name hexane. Which type is the most stable and which is the least stable according to your data
Using a band diagram, explain how magnesium can exhibit metallic behavior when its 3s band is completely full.
consider the equation aaq 2baq 3caq 2daq. in one experiment 45.0 ml of 0.050 m a is mixed with 25.0 ml 0.100 m b. at
If you had a pH of 7.0 in the body, how much ammonia from the kidney would you need to add to get to a pH of 7.38? Assume there's five liters of blood in the body. Essentially you're taking away protons with the use of ammonia.
Suppose 50.0 ml of 0.25 m COCL2 solution is add to 25.0ml of 0.350 m NiCl2 solution calculate the concentration, in moles per liter , of each of the ions present after mixing . assume that the volumes are additive.
When the mixture is ignited, gases are produced and 815 J of energy is released. To what volume will the gases expand against a constant pressure of 635 mmHg, if all the energy released is converted to work to push the piston?
