What are the missing coefficients for the skeleton equation below?

Cr(s) mc035-1.jpg Fe(NOmc035-2.jpg)mc035-3.jpg(aq) mc035-4.jpg Fe(s) mc035-5.jpg Cr(NOmc035-6.jpg)mc035-7.jpg(aq)
Group of answer choices

2, 3, 3, 2

1, 3, 3, 1

4, 6, 6, 2

2, 3, 2, 3

The correct coefficients are 4, 6, 6, 2.

Therefore, the missing coefficients are:
Cr(s) + 6 Fe(NO3)3(aq) --> 2Cr(NO3)6(aq) + 6Fe(s)
