How to calculate Q in Nernst Equations, we used 0.10M solutions in all of our half cells. Nernst equation: Ecell = E0cell - RT/nF ln Q Overall reactions: Cu(s) + Pb2+(aq) ~ Cu2+(aq) + Pb(s) and 3Pb(s) + 2Al3+ ~ 3Pb2+ 2Al(s) Thank you!

Using your experimental data, calculate E0cell. Standard voltaic cells contain 1M solutions, but we used 0.10M solutions in all of our half cells. Use the Nernst equation to calculate the standard cell potential (E0cell) from your measured Ecell and Qrxn. Data: Nernst Equation...

An airplane is flying at an altitude of 6 miles and passes directly over a radar antenna. When the plane is 10 miles away, the radar detects that the distance is changing at a rate of 240 mph. what is the speed of the plane? This is an implicit differentiation problem

No. this is the sample I did. Cu+(s)+/Cu2+aq)//Al3(aq)+/Al(s) is this right? Anode = Cu+(s)+/Cu2+(aq) - +0.337 Cathode = Al3+(aq)+/Al(s) - -1.66 Overall redox reactions: -0.337 - -1.66 = 1.323?

ok thank you!

dG=? . how do I start this problem? Do I use dG= -RT*ln*K? dG=-(0.008314 kj/k*mol) (61+ 273.15) ln (29.24)?? I tried this and it is wrong.
Chemistry
DrBob222, I don't know how to solve this problem either. And yes, this is the question for this problem. I even double check it. Please help. Chloroform (CHCL3) has a normal boiling point of 61 'C and an enthalpy of vaporization of 29.24 kJ/mol. What is the value of de...
