On a sheet of paper, balance the following redox reaction using the Half Reaction Method Show all of you make sure you upload it so I can grade it and give partial credit for as much as I can HNO2(aq)+HI(aq)>NO(g)+I2(s)+H2O( l)
plz help​

What are the first two quantum numbers for the electrons located in subshell 4d? what are the first three quantum numbers for the electrons located in subshell 2s? how many electrons can be held in a sublevel l = 3? how many electrons can be held in the energy level n = 4? how many electrons in an atom can share the quantum numbers n = 4 and l = 3?
