Question

What are the missing coefficients for the following equation:
___Cr + ___Fe(NO3)2 ___Fe + ___Cr(NO3)3

  1. 4, 6, 6, 2
  2. 2, 3, 2, 3
  3. 2, 3, 3, 2
  4. 1, 3, 3, 1

hintHint:

Number of elements before and after the reaction should be same.

The correct answer is: 2, 3, 3, 2


    To make is equation balanced and to find out the missing component, we should keep in mind that the number of elements before and after the reaction should be the same.
    Balanced equation is
    2Cr + 3Fe(NO3)2 →3Fe + 2Cr(NO3)3
