(a)What is special about a reversible process?
(b) Suppose a reversible rocess is reversed, restoring the system to its original state. What can be said about the surroundings after the process is reversed?
(c) Under what circumstances will the vaporization of water to steam be a reversible process?
(d) Are any of the processes that occur in the world around us reversible in nature? Explain.
Explain what atomic species is being reduced. Gold miners then reacts the basic aqueous product solution with Zn dust to recover the gold metal. State a balanced redox reaction for the recovery process with zinc.
How long does it take to deposit a coating of gold 1.00 um thick on a disk-shaped medallion 4.00 cm in diameter and 2.00 mm thick at constant of 86A? The density of gold is 19.3 g/cm^3 and the gold is from an Au(III) solution.
The definition of PH is PH = -log[H+], where [H+] is the concentration of the hydrogen ion. If [H+] = 1.2 x 10 ^-5, determine the PH using correct number of significant figures.
Perform the calculatons for the extraciton of 100 mg of P in 300mL of water with three 100-mL portions of ether. assume the partition coefficient is 3.5
As the water passed through the extractors, the analyte was adsorbed onto the solid phase. It was subsequently eluted with 10.0mL of hexane. Gas Chromatography resolute that there was 14.2 mg/L of analyte in the hexane. Explain what is the concent..
A solution of KOH is prepared and standardized against 0.5418g KHP. The phenolphthalein endpoint was reached by the addition of 25.91mL KOH. What is the molarity of the KOH solution
At 25C the acid dissociation constant for formic acid is 6.9x10-4. Calculate DG for this reaction. R=8.31x10-3 kj/K) Can you please help me work this problem.
When aqueous solutions of K2SO4 and Pb(NO3)2 are combined, PbSO4 precipitates. Calculate the mass, in grams, of the PbSO4 produced when 1.74 mL of 0.154 M Pb(NO3)2 and 3.64 mL of 0.75 M K2SO4 are mixed. Calculate the mass to 3 significant figures.
A solution is made by dissolving 0.75 g of salt in 100.00 g of water. Calculate the % m/m for the solution. *0.74% m/m *0.75% m/m *7.5% m/m *7.4% m/m
Calculate the pH at the equivalence point in a 0.10 M acetic acid/0.10 M sodium hydroxide titration when 27.4 mL of NaOH was used in titration.
Description of amino acids, Chiral compounds occur when a carbon atom has four different things bonded to it. All but the simplest amino acids (glycine) are chiral because the alpha carbon has an amine group
