46.which of the following is NOT true of the voltaic
cell:
a)The electrode of Cu acts like an anode
b)the reduction occurs in the electrode of Cu
c)The mass of the electrode of Zn(s) decreases at
the time following the reaction
d) the electrons flo from the electrode of Zn to the
electrode of Cu
47.calculate E cell at 25 celcius for the following
reaction below the standard condicions.
use the following potencials of standard reduction.
48.select the simbol that represents a positron
2- 46. Cuál de los siguientes NO es cierta sobre cuta celda voltaicu: Zn()|zu (1M)||Cu? (1 M) Cu()? (a) el electrodo de Cu(s) actúa como ánodo (b) la reducción ocurrirá en el electrodo de Cu(8) (c) la masa del electrodo de Zn(s) disminuirá a medida que ocurra la reacción (d) los electrones fluyen del electrodo de Zn(s) al electrodo de Cu(8) 47. Calcule Eolda a 25°C para la siguiente reacción bajo condiciones estándar. 2Ag +(ac) + Pb(s) + So, (ne) - 2Ag(s) + PbSO,(s) Use los siguientes potenciales de reducción estándar. PbSO.(s) + 2 e Pb(s) + S0,-(ac) E' = -0.356 V Agt(ac) + e → Ag(s) E = +0.799 V (a) -1.155 V (b) +1.155 V (c) -0.443 V (d) +1.174 V 48. Seleccione el símbolo que representa un positron.
