What is the absolute entropy of 1 mole of He atoms at 25.0 degrees celsius and 1.000 atm pressure? Compare this with the literature value of 126.04 J/molK.
Evaluate the efficiency for a compression ratio of 10:1. Assume that, in state A, V = 4.00 dm3, p = 1.00 atm, andT = 300 K, that VA = 10VB , pc /pb = 5, and that Cpm = 7/2 R
Draw the experimental outcome for a titration analysis involving a titrant and titrand (the pH vs. volume titrant added response curve), wherein the titrand is the weak, monoprotic base aniline (0.05000 F, 0.10000 L), and the titrant is a strong m..
What mimimum hydronium ion concentration (M) would be needed to prevent precipitation of cupric hydroxide (Cu(OH)2 Cu2+ + 2OH- , Ksp = 2.2 x 10-20) from a solution containing 0.010 M Cu2+ ion?
What atomic or hybrid orbitals make up the sigma bond between I and I in triiodide ion, I3-?. What is the approximate I-I-I bond angle?
The minimum energy needed to eject an electron from a sodium atom is 4.41 X 10^-19. What is the maximum wavelength of light, in nanometers, that will show a photoelectric effect with sodium?
Use this mass and the dilution volumes to calculate the ACTUAL molarity of the sulfuric acid in the INITIAL solution.
consider a stone column 3.00 ft in diameter and 10.00 ft high. What is is mass in pounds if its density is 3.50 g/mL.
calculate the mass in grams of NaCl Present in each of the following solution A. 11.5 g Of 6.25 % NaCl Solution B. 6.25 g of 11.5 % NaCl solution
A 9-mm Xian short-barrel experimental pistol is fired and the reacting, exploding gases push the bullet down the barrel of the gun. The pressure is recorded as the bullet accelerates to the exit.
28.80 mL of a 0.1726 mol/L EDTA solution is required to titrate a sample to the equivalence point. How many moles of divalent metal cations were in your sample
Liquid-in-glass thermometer are of two types:mercury in glass and alcohol plus red dye in glass. the dependence of volume on temperature of mercury and alcohol.
Its titrated with NaOH. Being a triprotic and having 3 acid dissociation constants Ka1, Ka2, Ka3 one would expect to see three equivalence points. Why does it only show two equivalence points
