Describe an electrochemical cell for which the following are the cell reactions. (A cell description includes the physical description of the anode and anode compartment with dissolved species, cathode and cathode compartment with dissolved specieds, direction of electron flow, std. cell potentials, and an expression for the cell potential. Also include the short-hand single line notation for each cell.)
a. Zn(s) + CuSO4 --> ZnSO4 (aq) + Cu(s)
b. Cd(s) + NiOOH(s) --> Cd(OH)2(s) + Ni(OH)2 (s) (unbalanced)
To identify a diatomic gas x2 a research carried out the following experiment: She weighed an empty 1 L bulb, then filled it with the gas at 1.10 atm and 23.0 C and weighed it again. The difference in mass was 1.27 g. Identify the gas.
Cells use the hydrolysis of adenosine triphosphate, abbreviated as ATP, as a source of energy. Symbolically, this reaction can be represented as ATP(aq) + H2O(l) ? ADP(aq) + H2PO4-(aq)
