Set up a cell that has a Zn Zn electrode in a 1.0 M aqueous Zn 2 + Zn2+ solution on the left side and a Ag Ag electrode in a 1.0 M aqueous Ag + Ag+ solution on the right side. Add the salt bridge. What are the half‑reactions for the anode and cathode that are associated with this chemical reaction? Include physical states.

explanation:

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
