Explanation:
To draw a Lewis structure of a molecule, you place the least electronegative atom (Xe) as the central atom, with the more electronegative atoms (O) surrounding it.
Then you distribute the electrons around the atoms, giving every one an octet and placing any extra electrons on the central atom.
This procedure gives you four possible Lewis structures, so the actual structure is a resonance hybrid of them all.
Structure D has no formal charges, so it is the major contributor.
Answer:
Explanation:
(a) Balanced equation
2HNO₃ + Ca(OH)₂ ⟶ Ca(NO₃)₂ + 2H₂O
(b) Moles of Ca(OH)₂
(c) Moles of HNO₃
The molar ratio is 2 mol HNO₃:1 mol Ca(OH)₂
(d) Molar concentration of HNO₃
