An electrochemical cell has an Eocell of 2.00 V and transfers 1 mole of electrons. The Faraday constant is 96,485 C/mol e-. What is the value of delta G?
energy to heat a certain sample of pure silver from 12.0 C to 18.2 C. Calculate the mass of the sample of silver.
In the reaction AH3 +H+ = AH4+, AH3 has a dipole moment and AH4+ does not. Predict the number of lone pairs that may exist on A in AH3. Hint: Find more than a single number of lone pairs that work.
Clancy the dog ingested 50 mL of 50% methanol. How much of 12% ethanol wine must Clancy consume in order to lower the activity of his ADH on methanol to 5% of it's normal value if the Km values of canine ADH for ethanol and methanol are 1 millimol..
elements from lanthanum to lutetium, As the atomic number gets larger, the atomic radius be same or decreased. How do you account for this general trend
The sample requires 48.24 mL of 0.08893 mol/L Na2S2O3 to reach the equivalence point. Assuming that the AU3+ and Li+ ions are unreactive during the titration, determine the mass percent of LiCLO in the sample.
When the ln( kE2 / kE1 ) is plotted vs. 1/T the resulting linear graph has the slope of - 4.8 and intercept of 6.1What is the difference in activation energies of the two mechanisms? For which mechanism are the reactive collisions more efficient?
The precipitate, after having been filtered and air-dried, has a mass of .284 g. The limiting reactant in the salt mixture was later determined to be CaCl2x2H2O.
2) Calculate the concentration of an aqeuous solution of Ca(OH)2 pH of 12.05.
The volume of each glass was 250mL. How much heat, in kJ, did the body have to supply to raise the temperature of the water to body temperature (37 C)?
Calculate the molarity of a solution of HBr if 34.80 mL of the HBr solution neutralize 0.834 g of Na2CO3. The following is the unbalanced equation for the reaction
