Which is a correct set of values of m for one of the subshells of n = 2? –1, 0, 1
–1, –2, 0, 1, 2
–1, –2, –3, 0, 1, 2, 3
–1, –2, –3, –4, 0, 1, 2, 3, 4

-1, 0, +1

Explanation:

n = 2n = 0,1,2,3,n

l= n-1 = 2-1 =1.l= 1,2,3,4n-1

m = l is 1 so now write the value of magnetic moment as-1,0,+1

for eg . if the value of l comes to 2 then u will write the value of m as -2,-1,0,+1,+2 .

i hope it will help u

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
