Refer to the following abbreviated standard reduciton potential table. Which one is the of the following reactions would be considered NON=SPONTANEOUS?
Al^3- + 3e^- aAl -166 V
Zn^2+ + 2e^- a Zn -0.76 V
Pb^2+ + 2e^- a Pb - 0.13 V
2H^+ + 2e^- a Hsub2 0.00 V
Cu^2+ + 2e^- a Cu+0.34 V
Ag+ +e-a Ag+0.80 V
a. 2 Ag^+ + Cu --> 2 Ag + Cu^2+
b. 2 H^+ + Pb --> 2H + Pb^2+
c. 3 Zn^2+ + 2Al --> 3Zn^+ 2Al^3+
d. Hsub2 + Zn^2+ --> Zn + 2H^+
Half-life of first order process, A reactant undergoes a dissociation reaction A r arrow 2B which follows first order kinetics. The initial concentration of reactant A is .4000
What will be the pH if 0.00820 mol of HA (pKa=2.34) and 0.00820 mol of A- are dissolved in water to make 1.000 L of solution? this is a dilute acid problem
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.
what is the molar mass of the protein? A solution of 7.50 mg of a small protein in 5.00 ml of aqueous solution has an osmotic pressure of 6.80 torr at 23.1 degrees celcius.
The products include Cr3+ ion and I2. What was reduced in the reaction and what was the reducing agent?
Using standard molar entropy values, calculate delta standard molar entropy values for the following reactions. In each case account for the sign of delta standard molar entropy.
A sample containing 2.40 {rm moles} neon gas has a volume of 8.00 {rm L}. Assume that the pressure and the temperature remain constant.
A 6 cm string is fastened at both sides is plucked. What is the wavelength of the n = 3 standing wave? How many nodes does it contain.
Is 2-methyl-2-propanamine (C4H11N) a primary amine, secondary amine, tertiary amine, or quaternary ammonium salt? 2) Is N-methyl-2-propanamine a primary amine
When the reaction that occurs finally ceases, what will be the mass of unreacted copper in the bar? What will be the mass of silver metal that "plates out" of solution (that is, what mass of silver metal is produced by the reaction)
Aminotransferases are enzymes that catalyze the interconversion of amino acids and ?-keto acids. In this way, they can provide the carbon needed for gluconeogenesis from amino acids supplied by dietary protein
Crude gunpowders often contain a mixture of potassium nitrate and charcoal (carbon). When such a mixture is heated until reaction occurs, a solid residue of potassium carbonate is produced.
