The overall reaction for the discharge of a nonrechargeable alkaline battery is 2MnO2(s) + Zn(s) + 2H2O(1) 2MnO(OH)(s) + Zn(OH)2(s) The cathode of a brand new, undischarged alkaline battery is made of O MnO(OH)(s) Zn(OH)2(s) Zn(s) O Mn(OH)2(s) MnO2(s)
During the discharge (operation) of a 1.5 alkaline battery, Robin determined that 6.33g of zinc was oxidized to zn(oh)2. a) what mass of Mno2 was reduced at the cathode. b) How many coloumbs of electron charge we're transferred from zn to Mno2 ? c) How many joules of electrical energy we're produced ?
9. __/10 pts) Last one!!! A silver button battery relies upon the following reaction: Zn(s) + Ag20(3) → ZnO(s) + 2Ag(s) A) What is Eºcell? B) If a cell can run until 80% of the zinc is consumed, how many days will a cell produce a current of 0.85 microamps (10 amps) if it contains 0.75 g of zinc?
The chemical reaction occurring during the discharge of a lead storage battery can be represented by the equation: Pb(S) + PbO_2(s) +2H_2 SO_4 (aq) rightarrow 2 PbSO_4 (s) + 2 H_2 O(I) Which is the limiting reagent and the amount of PbSO_4 produced if 53.0 g of Pb, 77.3g of PbO_2, and 534mL of 0.544 M solution of H_2 SO_4 is used?
