For those reactions that are redox, indicate which elements are reduced. PA(s)+10HCIO(a)6H20)4H3 PO4(a) 10HCl(ag) Br2(1) +2K(s) KBr(s) CH3CH2OH(1) +302(g) ? 3H2O(l) +2CO2(g) Drag the appropriate items to their respective bins Reset Help Element reduced when P4 and HCIO react Element reduced when Br2 and K react Element reduced when CH3CH2OH and O2 react Not an element reduced Solution In the first reaction Cl oxidation no. Changes from +1 to -1 and in the second reaction Br gets reduced. In the third reaction oxygen geta reduced from 0 to -1. So here : Element reduced when P4 and HClO react : Cl Element reduced when Br2 and K react : Br Element reduced when CH3CH2OH and O2 react : O Not an element reduced : P , K , C , H .
