NO + 3Cu2++ 2H2O -----> 3Cu+ + NO3-+ 4H+
In the above redox reaction, use oxidation numbers to identify the element oxidized, the element reduced, the oxidizing agent and the reducing agent.
Based on the standard reduction potential, which species is oxidized when current is allowed to flow? B. Calculate the value of Q, the reaction quotient, for this cell reaction. C. Calculate the actual cell potential at 25 degrees C.
(a) Does the equilibrium shift to the left or to the right when some O2 (g) is removed from the reaction mixture? (b) Does the equilibrium shift to the left or to the right when some NO (g) is added to the reaction mixture?
A 9.65-L container holds a mixture of two gases at 11 °C. The partial pressures of gas A and gas B, respectively, are 0.397 atm and 0.519 atm. If 0.160 mol of a third gas is added with no change in volume or temperature, what will the total pressu..
