Identify the cathode and anode and determine the standard cell potential for a voltaic cell composed of Co^2+/CO(2) and FE^3+/Fe(s).
Fe^(3+) +3e- > Fe = -0.037Co^{2+} + 2e- > Co = -0.277
Which is cathode, which is Anode, what is the standard potential of the cell
What is the volume of one mole of hydrogen gas at 273 K and 760 torr? What is the volume of one mole of oxygen gas under the same conditions?
To provide energy for the human, the O2 is reduced to H2O duing food oxidation by the following reaction: Recall that 1 ampere is equal to a charge of 1 coulomb per second flowing past a point in a circuit.
Four (4.00) moles of a perfect gas at 250.0 K and 1.50 bar pressure undergo a reversible isothermal compression until the pressure becomes 3.00 bar.
A liquid that has a density of 0.80 0.01g/ml and 0.80-0.01 g/ml is insoluble in cyclohexane. what is the liquid? what is the boiling point of cyclohexane at 600 mm hg?
Determine the volume of 0.375 mol of C4H10 gas under the same temperature and pressure conditions?
When the epoxide 2-vinyloxirane reacts with lithium dibutylcuprate, followed by protonolysis, a compound A is the major product formed. Oxidation of A with PCC yields B, a compound that gives a positive Tollens test and has an intense UV absorptio..
An element has three naturally occurring isotopes with the following masses and abundances (in parenthesis): 27.977 amu (0.9222); 28.974 amu (0.0469); 29.974 amu (0.0310). Calculate the atomic weight of the element.
Can someone show me how to draw the reciprocal lattice for a simple tetragonal structure with a=0.4nm and c=0.5nm?
Find the heat transferred (in kJ) when 5.50 L of ethylene glycol (d = 1.11 g/mL, see Table 6.2 for c) in a car radiator cools from 37.7°C to 23.0°C.
From the heats of reaction as given 3O2(g) ---> 2O3(g) DH = +284.6 kJ, 2H2(g) + O2(g) ---> 2H2O(g) DH = -483.6 kJ
