Problem Details

You may want to reference (Pages 138 - 144) Section 4.4 while completing this problem.

For those reactions that are redox, indicate which elements are oxidized.

P4(s) + 10HClO(aq) + 6H2O(l) →  4H3PO4(aq)+10HCl(aq) 

Br2(l) + 2K(s) →  KBr(s) 

CH3CH2OH(l) + 3O2(g)  → 3H2O(l) + 2CO2(g)
