FeCl3 + NaOH → NaCl + Fe(OH)3 What are the coefficients that should be added to balance this equation? Use complete sentences to explain your answer.
Explain how this chemical reaction demonstrates the conservation of mass.

FeCl3 + 3NaOH → 3NaCl + Fe(OH)3 .

Explanation:

Hello!

In this case, since balancing chemical reactions by inspection requires to equal the number of atoms of each element at both reactants and products side; for the given reaction:

FeCl3 + NaOH → NaCl + Fe(OH)3

We need three chlorine atoms at the right side and three OH⁻ ions at the left side, therefore we can write:

FeCl3 + 3NaOH → 3NaCl + Fe(OH)3

In such a way, since we equal the number of atoms to allow the reaction to be balanced, we evidence this balanced way of the reaction substantiates that matter cannot be created nor destroyed by means of the law of conservation of mass.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
