A beaker with 1.50×102mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 7.20mL of a 0.330\it M \rm HCl solution to the beaker. How much will the pH change? The {\rm p}K_{\rm a} of acetic acid is 4.760.
NH4CO2NH2(s)->2NH3(g) +CO2(g) (at equilibrium) starting with only the solid it is found at 40C the total gas pressure is 0.363 atm calculate equilibrium constant Kp
Calculate how much energy in the form of heat is available from 100mL of this mixture and compare it with the amount available from pure gasoline
Helium atoms do not combine to form He2 molecules, yet He atoms do attract one another weakly through
AgBr is the light-sensitive compound in most photographic films. Assume, when film is exposed, that the light energy absorbed dissociates the molecule into atoms.
What is the minimum frequency of light (nm) that can be used to eject electrons from the surface of this metal via photoelectric effect
Standard reduction potentials for the Pb2+/Pb and Cd2+/Cd haf-reactinos are -.13V and -.40C, respectively. At what relative concentrations of Pb2+ and Cd2+ will these half-reactions have the same reduction potential?
Analysis with an elaborate instrument indicates that substance A contains two elements. Substance B and substance C react to give a new substance D.
Red phosphorus is fairly stable, while white phosphorus will ignite spontaneously in air above 50 C. Determine the change in entropy for the conversion of the white form to the red form
Which choice is closest to the longest wavelength that will remove an electron from the n=3 level of the hydrogen atom? (hint: what would you use for the value of nfinal when the electron is completely removed from the atom?)
Determination of Molecular SO2 Needed for Protecting Wine, You have just finished fermenting a wine and the pH = 3.7. You need 2mg/L "molecular" SO2 to protect the wine. What level of free SO2 do you have to add to achieve the level of the molecul..
You dilute 1g of the soap 1:106 and plate it on standard plate count agar. After 24 hours of incubation, there are 168 colonies. How many bacteria were on the soap? How did they get there?
Solid benzoic acid, C6H5COOH(s), is often used to determine the heat capacity of a bomb calorimeter, because the constant volume heat of combustion of this compound is known with high precision
