Show that the energy transferred as heat when the pressure on an incompressible liquid or solid is increased by delta P is equal to -alphaTVdP. Evaluate q when the pressure acting on 100cm cubic of mercury at ) degre celcius is increased by 1.0kbar ( alpha =1.82x10^-4K^-1)
The solubility of N2 in blood at 37 oC and at a partial pressure of 0.80 atm is 5.6 X 10-4 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 3.1 atm. Assume that the total volume of the blood in the body is 5..
Once the system has reached equilibrium, 5.00 g of NO2 is injected into the vessel, and the system is allowed to equilibrate once again. Calculate the mass of NO2 in the final equilibrium mixture.
A flat 103-turn current-carrying loop is immersed in a uniform magnetic field. The area of the loop is 5.47 cm2 and the angle between its magnetic dipole moment
Calculate the energy of the frequency at which they are broadcasting. (In kilojoules)
The solution filtered , then we took 25 mL of this unknown acid for titration. we use NaOH base for titration ,the volum of titrated base when it reach the equivalence point was 3.2 mL . and the concentration of NaOH is 0.1 M.
You are performing site-directed mutagenesis to test predictions about which residues are essential for a protein's function. Which of each pair of amino acid substitutions listed below would you expect to disrupt protein function the most
A saturated solution of iron(II) hydroxide at 25°C contains 1.0 x 10-5 M Fe2+ ions. Determine the ?G° for the solution at this temperature.
that the reaction was endothermic. If the enthalpy of reaction is negative, then we say that energy was released or that the reaction was exothermic. Most chemical reactions are exothermic.
The first-order decomposition of SO2Cl2 to sulfur dioxide gas and chlorine gas at 320°C has a half-life of 8.75 hr. If one begins with 600. mmHg of pure SO2Cl2 in a 5.00-L flask at 320°C
Calculate the volume of a solution NaOH c=0.2 mol/l necessary to neutralize v=200 ml of solution HCl c=0.1 mol/l.
