Answer from: sandy8438

FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl

Explanation:

You are given a skeleton equation, or unbalanced equation.

FeCl₃ + NaOH → Fe(OH)₃ + NaCl

Count the number of atoms on each side. If there is 1 atom, the subscript is not written. If the subscript to the right of a bracket, it belongs to each element in the bracket.

Reactants → Products

Fe 1 Fe 1

Cl 3 Cl 1 Not balanced

Na 1 Na 1

O 1 O 3 Not balanced

H 1 H 3 Not balanced

The number of each element must be the same in the reactants and products. We can see that Cl (chlorine), O (oxygen) and H (hydrogen) have different numbers.

Write in coefficients in front of formulas (separated by + sign). Coefficients multiply each subscript (or "1" if not written) in the formula. Recount the atoms until you have equal reactant and product atom numbers.

I see that I need more chlorine in my products. Multiply the formula that has "Cl" by 3.

FeCl₃ + NaOH → Fe(OH)₃ + 3NaCl

Reactants → Products

Fe 1 Fe 1

Cl 3 Cl 3 Cl is balanced now.

Na 1 Na 3 Not balanced

O 1 O 3 Not balanced

H 1 H 3 Not balanced

Fix the "Na" now. Multiply the formula with "Na" on the left by 3.

FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl

Reactants → Products

Fe 1 Fe 1

Cl 3 Cl 3

Na 3 Na 3

O 3 O 3

H 3 H 3

Each side has the same number of each element. Therefore, this is balanced now.

Balanced formula:

FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl

Answer from: Quest

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
