Steady State Reaction

In the course reader, it mentions the pre-equilibrium approach and the "stead state" approach as methods of confirming the reaction mechanism. What is the steady state approach?

Calculating Cell Potential

If E(cell)=E(cathode)-E(anode), why, when the E for the oxidation(anode)=-1.50V, and the E for the reduction(cathode)=0.96V, is the answer 0.96V-1.50V=-0.54V. Shouldn't it be 0.96V-(-1.50V)??

Writing coordination compound formulas

When writing the formula for a coordination compound, do you base the alphabetical order off of the name of the molecules and ions, or off of the actual atoms. For example: pentaamminechloronickel (III) chloride, would the formula be [NiCl(NH3)5]Cl2 or [Ni(NH3)5Cl]Cl2. Basically would you base alpha...

Re: Question #M9 a) Write the net ionic equation

Hi, Start off by writing out the full molecular equation with the states: Cu(NO3)2(aq) + 2NaOH(aq) = Cu(OH)2(s) + 2NaNO3(aq) Then write the full ionic equation, splitting aqua compounds into ions. Solids, liquids, and gasses must be left as compounds: Cu(2+)(aq) + 2NO3-(aq) + 2Na+(aq) +2OH-(aq) + Cu...
