Balancing Chemical Equations
can someone balance this equation for me
Fe^2+ Cr2 O7^2- --> Fe^3+ + Cr^3+
Thank you!:D
1 answer
How much do you know how to do? Fe goes from an oxidation state of +2 on the left to +3 on the right. Cr (EACH Cr) goes from +5 on the left to +3 on the right. The first thing you do is multiply Cr^+3 on the right by 2. It may change later.
