It is given that the electrochemical cell is at 298K. At time zero [Zn 2+ ]= 1.0 x 10 ^-3 M and [Ag +] = 0.500 M. Calculate the molarities of zinc and silver ions after a current of 2.00 amperes flow for 20 hours. Please show step by step and the units you are using.
Effects of H2O2 conc with catalyst ---- michaelis equation demonstration
I have come across a major stumbling block with my kinetics (michaelis equation). How do I predict using the michaelis equation the volume of oxygen collected for the given concentrations? Please could you give an example of the complete working out for any given concentration, where necessary (if required) making up val ...continues

During lab I made 4 cells using CuSO4(aq) solution 1. one with a Cu (s) electrode on the negative terminal, and Al(s) on the positive terminal.....nothing appeared to happen during this reaction 2. Cu (s) on negative, Ni (s) on positive....bubbles formed at the anode 3. Cu (s) on positive, Al (s) on negative..... Cu pla ...continues
I am trying to determine the separate half reactions and overall cell process for the following and need some help: a minature battery is composed of Zn and a paste of KOH, water, mercury (II) oxide, and mercury. Zinc and potassium hydroxide are consumed, mercury is deposited, and potassium zincate is formed. Also, what ...continues
Hemoglobin (Hb) molecules in blood bind oxygen and carry it to the cells, where it takes part in respiration. The first step in the binding of oxygen is first order in hemoglobin and first order in dissolved oxygen, with a rate constant of 4 x 10^7 L mol-1 S-1. Hb(aq) + O2(aq) ------------> (HbO2) (aq) How can I calcula ...continues
