Solid iron(III) hydroxide reacts with gaseous hydrogen chloride forming water and aqueous iron(III) chloride.

Can someone show me how to write this? I'm entering in online hmwk and it keeps telling me I'm wrong, but I'm not sure what's wrong with it. I would post my answer here, but I dont know how to type some of the subsrcipts (and stuff) in this box.

Fe (OH)3 + 3HCl ---> 3H2O + FeCl3

The three's after hydroxide and chloride are in subscript  :)

anonymous · Answer

$$Fe (OH)_{3} + 3 HCl \rightarrow 3H _{2} O + FeCl _{3}$$

anonymous · Answer

Don't forget the (s) for the solid, (g) for the gas and (aq) for the aqueous solution and (l) for the water.
