Chemistry balance skeleton reaction? balance the following skeleton reactions and identify the oxidizing and reducing agents.; include states-of-matter ! 1.bh4‾(aq) + clo3‾(aq) → h2bo3‾(aq) + cl ‾(aq) [basic] 2.cro42-(aq) + n2o(g) → cr3+(aq) + no(g) [acidic]

The correct balanced redox reactions would be as follows:

1.BH4‾(aq) + ClO3‾(aq) → H2BO3‾(aq) + Cl ‾(aq) [basic]
By using the half-reaction method, we will obtain the following: 
BH4-(aq) + 8 OH- = H2BO3- + 5H2O + 8 e- 
ClO3- + 3H2O + 6 e- = Cl- + 6OH- 

The LCM for the 2 half-reactions would be 24. We add these reactions as follows: 

3 BH4- + 24 OH- = 3H2BO3- + 15 H2O + 24e- 
4 ClO3- + 12 H2O + 24e- = 4Cl- + 24OH-

3 BH4- + 4ClO3- = 3H2BO3- + 4Cl- + 3H2O 

2.CrO42-(aq) + N2O(g) → Cr3+(aq) + NO(g) [acidic]
By the same procedure above, 

(CrO4)2- + 8 H+ + 3 e- = Cr3+ + 4 H2O 
N2O + H2O = 2 NO + 2 H+ + 2 e- 

The LCM would be 6. 

2 (CrO4)2- + 16 H+ + 6 e- = 3 Cr3+ + 8 H2O
3 N2O(g) + 3 H2O(l) = 6 NO(g) + 6 H+ + 6 e- 

2 (CrO4)2- + 3 N2O + 10 H+ = 3 Cr3+ + 6 NO + 5 H2O
