So i wrote a net ionic equation, and I believe is wrong.

Fe(ClO4)3.
I wrote 3H+(aq) + Fe(OH)3(s) = Fe3(aq)+ + 3H2O (l)
Had to come up with the acid and base that would form the compound

To check if your net ionic equation for the compound Fe(ClO4)3 is correct, we first need to determine the acid and base that would form this compound.

In this case, Fe(ClO4)3 is a salt formed from the reaction between an acid and a base. To identify the acid and base, we need to break down the compound into its respective ions. Fe(ClO4)3 dissociates into Fe3+ cations and ClO4- anions.

However, Fe(ClO4)3 is not formed from a specific acid and base reaction. It is actually formed by the reaction between iron(III) chloride (FeCl3) and perchloric acid (HClO4).

So, the balanced equation for this reaction is:

FeCl3(aq) + 3HClO4(aq) → Fe(ClO4)3(aq) + 3HCl(aq)

To write the net ionic equation, you need to eliminate the spectator ions. In this case, the spectator ions are Cl- and H+.

The net ionic equation is:

Fe3+(aq) + 3ClO4-(aq) → Fe(ClO4)3(aq)

Therefore, your net ionic equation, 3H+(aq) + Fe(OH)3(s) = Fe3(aq)+ + 3H2O (l), is incorrect for the compound Fe(ClO4)3.

To determine if your net ionic equation is correct, let's first check if the given compound, Fe(ClO4)3, is an acid or a base.

In this case, Fe(ClO4)3 is an acid because it contains a metal cation, Fe3+, and the perchlorate anion, ClO4-. When dissolved in water, it will dissociate into ions.

Now, let's find the correct acid and base to form the compound Fe(ClO4)3.

The formula Fe(ClO4)3 suggests that the acid is perchloric acid (HClO4) and the base is a compound with a hydroxide ion (OH-).

To write the net ionic equation, we need to write the dissociation of the acid and the base, and then find the balanced equation.

Perchloric acid (HClO4) dissociates into H+ and ClO4- ions.
HClO4(aq) → H+(aq) + ClO4-(aq)

The base you've chosen, Fe(OH)3, is incorrect because it contains the hydroxide ion but does not react with perchloric acid to form Fe(ClO4)3. Instead, let's choose a base that contains OH- ions, such as sodium hydroxide (NaOH).

Sodium hydroxide (NaOH) dissociates into Na+ and OH- ions.
NaOH(aq) → Na+(aq) + OH-(aq)

Now, we can write the balanced equation by combining the ions from the acid and the base:

H+(aq) + OH-(aq) → H2O(l)

Finally, the net ionic equation is obtained by removing the spectator ions (ions that appear on both sides of the equation without undergoing any changes):

H+(aq) + OH-(aq) → H2O(l)

Therefore, the correct net ionic equation for the reaction between perchloric acid (HClO4) and sodium hydroxide (NaOH) to form water (H2O) is H+(aq) + OH-(aq) → H2O(l).

From the phrasing of the question, I'm not certain of the question; however,

the molecular equation to form Fe(ClO4)3 is
Fe(OH)3 + 3HClO4 ==> Fe(ClO4)3 + 3H2O but the net ionic equation for that is
(3H^+ + 3(OH^-) = 3H2O
