If you mean: -4+3+2s = 15 then s = 8
There are 8 atoms of hydrogen present in NH4 2S. This is because there are 4 hydrogen atoms in each ammonium ion (NH4+) and there are 2 ammonium ions in NH4 2S.
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
4 (apex lol)
4 (apex lol)
There is only one 2s orbital in an atom.
If you mean: 4(2s-1) = 7s+12 then the value of s works out as 16
22+22
you do 2 + 2
The chemical formula for ammonium sulfide is written as (NH4)2S. In each molecule, there are 2x4=8 atoms of hydrogen.
25 of them
310.
