Which of the following redox reactions do you expect to occur spontaneously in the forward direction under standard conditions? Check all that apply. Ni(s)+Zn2+(aq)→Ni2+(aq)+Zn(s) Pb(s)+Mn2+(aq)→Pb2+(aq)+Mn(s) Correct! Ni(s)+Pb2+(aq)→Ni2+(aq)+Pb(s) Correct! Cr(s)+3Ag+(aq)→Cr3+(aq)+3Ag(s)

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.

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

cu2o

plasma - state of matter made up of electrically charged particles
