<span>(8.5 x 10^-3 mol) / (0.0320 mol/L KCN)=0.265625 L=265.625 ml.
This is the volume of a 0.0320 M KCN solution that would give a median lethal dose to a 185 lb person.</span>
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near itshydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
<span>The notation is not written in the correct order as the 4s subshell should appear before the 3d subshell.
</span>The correct order in an electron configuration would be:
1s , 2s , 2p , 3s , 3p , 4s , 3d , 4p , 5s , 4d , 5p , 6s , 4f , 5d , 6p ,..
So, for germanium the electronic configuration should be;
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p²
