The following are the steps involved in drawing Lewis structure of the polyatomic trisulfide anion 
:
Total number of valence electrons = 
Resonance is not possible in this ion. The molecular geometry of the ion will be bent as there are two lone pairs and two bond pairs on the central atom.
Answer:
32 mols of water
Explanation:
2H2 + O2 ==> 2H2O
What your givens are telling you and what the equation is saying is that
for every mol of O2, you get 2 mols of H2O
So you could do it with the proportion about.
1/16 = 2/x Cross multiply
x = 16 * 2
x = 32
Valleys i think !!! possibly
The isotopes of an element differ in the number or neutrons whereas the number of protons or electrons of a neutral atom stays the same. The molar mass of the element is based on the percent abundances of different isotopes and the individual molar mass of each isotope.
