A silver oxide-zinc cell maintains a fairly constant voltage during discharge (1.60 V). The button form of this cell is used in watches, hearing aids, and other electronic devices.
The half-reactions are:
Zn(s) + 20H-(aq) — Zn(OH)2(s) + 2e-
Ag2O(s) + H2O(l) + 2e — 2Ag(s) + 20H(aq)
(a) Identify the anode and the cathode reactions.
(b) What's the overall reaction in this galvanic cell?​

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
