net ionic equations?

Question

Balance these net ionic equations for redox reactions.

a.) Cr2O7 * 2- (аq)+Fe*2+ (aq) ----> Cr*3+ + (aq) + Fe* 3+ (aq) (in acid solution)

b.)Zn(s) + V2O5 (aq)--> Zn*2+ (aq)+ V2 O4 (aq) (in acid solution)

c.) N 2 O(g) + CIO*- (aq)--> CI*- (aq) +NO 2*- (aq) (in basic solution)

[ps) the numbers are small...(for example Nx)
pss..thank you guys so much for helping!!!!me..=)

Answer 1

14H(+) + Cr2O7(2-) + 6Fe(2+) -> 2Cr(3+) + 6Fe(3+) + 7H2O

2H(+) + Zn + V2O5 --> V2O4 + Zn(2+) + H2O

2OH(-) + 2ClO(-) + N2O --> H2O + 2Cl(-) 2NO2(-)
