In a chemistry experiment, 6.15 moles of iron (III) chloride is reacted with 19.5 moles of ammonium hydroxide according to the reaction:
FeCl3 + 3 NH, OH → Fe(OH)3 +3 NH, CI
Using a RICE table,
a) Identify the limiting reactant in the reaction.
b) Calculate the excess reactant in the reaction.
c) Find the moles of iron (III) hydroxide produced in the reaction.

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.
