Answer:
2,1,-1
Explanation:
The electronic configuration of oxygen is
The valence electrons are in the second principle quantum number, which means that the value of n = 2.
For, n =2,
l can be 0 or 1 which corresponds to s and p orbital respectively.
If l = 1 , which is p orbitals and it exits in 3 degenerate orbitals which has values of m = -1 , 0 , +1
<u>So, The possible set pf quantum number for the outermost valence electron of the oxygen atom is 2, 1, -1.</u>
Answer:
Water is a human necessity. Therefore, it is one of the first things a human settlement would need to have. A community cannot thrive without a water source.
Answer:
16 mol
Explanation:
3Cl2 (g) + 8NH3 (g) → N2 (g) + 6NH4Cl (s)
from reaction 8 mol 6 mol
given x mol 12 mol
8 : x = 6 :12
6x = 12*8
x = 12*8/6 =16 mol
Physical. No change in molecules. It goes from hard to liquid.
