What are the missing coefficients for the skeleton equation Cr(s) + Fe(NO3)2(aq) → Fe(s) + Cr(NO3)3(aq)?
gpt
2Cr(s) + 3Fe(NO3)2(aq) → 3Fe(s) + 2Cr(NO3)3(aq) would be the corrected balanced equation, so the coefficients are 2,3,3,2; though it is more likely 2,3,3,2 wasn't written, so alternatively, the coefficients are likely 2Cr, 3Fe, 3Fe, and 2Cr.
Explanation: To balance the chemical equation, the coefficients must ensure that each side has the same number and types of atoms for each element.
