A sample of 6.81 moles of cesium fluoride is reacted with 8.23 moles of xenon hexafluoride to produce
cesium xenon heptafluoride. Using the balanced
equation below, predict which is the limiting reactant
and the maximum amount in moles of cesium xenon
heptafluoride that can be produced.
CSF + XeF6 → CsXeF7

let that person have a turn to speak : )

it is the most commonly accepted one

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.
