Select the properly written and balanced equation for the following chemical reaction: Aqueous solutions of sodium hydroxide and iron (III) nitrate react to produce a precipitate of iron (III) hydroxide in an aqueous solution of sodium nitrate.

3NaOH (aq) + Fe(NO3)3 (aq) ➡ Fe(OH)3 (s) + 3NaNO3 (aq)

NaOH (aq) + FeNO3 (aq) ➡ FeOH (s) + NaNO3 (aq)

NaOH (aq) + Fe(NO3)3 (aq) ➡ FeOH3 (s) + NaNO3 (aq)

3NaOH (aq) + FeNO3 (aq) ➡ FeOH (s) + 3NaNO3 (aq)

a is properly balanced and depicts the correct reaction.

sweetburger · Answer

I guess the way to figure these out is to count up to make the atoms on the left side of the reaction are equivalent to atoms on the right side of the reaction.

Also you can instantly eliminate b,c,d because the reaction says that iron(iii) hydroxide is produced and choice a is the only answer with Fe(OH)3
