Suppose the average human body contains 6.00 L of blood with a Fe2+ concentration of 3.47×10−5 M . If a person ingests some cyanide bringing the concentration of cyanide in their blood to 1.20×10−5 M, what percentage of iron(II) in the blood would be sequestered by the cyanide ion?

answer; i do believe the correct answer is (river); /// good luck

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.

the answer is c.the valence of the atoms combine .
