Question

The alkali metals are readily soluble in liquid ammonia to give bright blue metastable solutions with unusual properties. Such solutions are unstable with respect to amide formation, as shown for potassium: 2K 2NH3 >2KNH2+ H2 Assign an oxidation number to each atom and verify that the total number of electrons lost is equal to the total number gained Enter the oxidation numbers under each substance in the box corresponding to the element label to the left. If a box is not needed, leave it blank. NH3 KΝH, На K K N н and the total number of electrons gained is For the reaction as written, the total number of electrons lost is О00 О00 О00

Answer 1

C hu G C 2X +gu k -K+2017 2NH + H2 Louidation - Reductions TK NU I KNE, I Hq onidation: 2K2KO theo +1 Nor of eas lost =2 Reduction : + 2NH₂ th y 2 who the No. of ees gained =2 Soo total no. of eas lost is equal to the total no. of ees gained. -3 for the reaction as written, the total number of electrons lost is 2 and the total numbed of electrons gained is 2 .
