Question

Fill in the coefficients that will balance the following reaction:

Answer 1

6NaC₂H₃O₂   +  Fe₂O₃   →   2Fe(C₂H₃O₂)₃  +  3Na₂O

Explanation:

Given equation;

      NaC₂H₃O₂   +  Fe₂O₃   →   Fe(C₂H₃O₂)₃  +  Na₂O

To find the coefficient that will balance this we equation, let us set up simple mathematical algebraic expressions that we can readily solve.

Let us have at the back of our mind that, in every chemical reaction, the number of atom is usually conserved.

      aNaC₂H₃O₂   +  bFe₂O₃   →   cFe(C₂H₃O₂)₃  +  dNa₂O

a, b, c and d are the coefficients that  will balance the equation.

 conserving Na;    a  = 2d

                       C:     2a  = 6c

                       H:     3a  = 9c

                       O;      2a + 3b  = 6c + d

                       Fe:     2b = c

let a = 1

    solving:

      2a = 6c

       2(1) = 6c

          c = $\frac{2}{6} = \frac{1}{3}$

      2b = c

          b = $\frac{1}{2} x \frac{1}{3}$ = $\frac{1}{6}$

     d = 2a + 3b - 6c = 2(1 ) + (3 x$\frac{1}{6}$  )  - (6  x  $\frac{1}{3}$) = $\frac{1}{2}$

Now multiply through by 6

  a = 6, b = 1, c = 2 and d = 3

             

                6NaC₂H₃O₂   +  Fe₂O₃   →   2Fe(C₂H₃O₂)₃  +  3Na₂O
