Question

Cr(s) mc015-1.jpg Fe(NOmc015-2.jpg)mc015-3.jpg(aq) mc015-4.jpg Fe(s) mc015-5.jpg Cr(NOmc015-6.jpg)mc015-7.jpg(aq)
Group of answer choices

2, 3, 2, 3

1, 3, 3, 1

2, 3, 3, 2

4, 6, 6, 2

Answer 1

The missing coefficients for the equation are:

2 Cr(s) + 3 Fe(NO3)2(aq) -> 3 Fe(s) + 2 Cr(NO3)3(aq)

So the correct answer is 2, 3, 3, 2.
