Consider the reduction half-reaction of carbon dioxide to formic acid (hcooh). co2(g) + 2h+ (aq) + 2e - hcooh e = -0.199v bubbling a pressure of 1 bar of carbon dioxide gas through an acidic solution with 1.0 mol l of which ion and metal will yield the most formic acid? a. aul(aq) and au(s) b. ag (aq) and ag(s) c. cu(aq) and cu(s) d. pb2+ (aq) and pb(s) e. zn? (aq) and zn(s)

it have destructive character

so what is the problem with your lab report and whats the subject of the lab report? i will you

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
