Where's the multiple choice for this
Explanation:
Metallic bond, force that holds atoms together in a metallic substance
Compounds with different boiling points - b.
Only because<span> fractional distillationworks by having a temperature gradient in the column therefore different length hydrocarbons condence at different rays of different temperatures.This works because longer chain hydrocarbons have higher boiling points. </span>
Answer:
Significant hydrogen bonding is possible in
Explanation:
- Hydrogen bonding takes place between an electronegative atom (O, N and F) and a H atom attached to those electronegative atoms.
- Lewis structure reveals that H atom attached to N in .
- In all other compounds no such H atom is present attached to O or N or F.
- Hence significant hydrogen bonding is possible only in
- Lewis structures are given below.
Answer:
Explanation:
N₂O₄(g) ⇄ 2 NO₂
N₂O₄ reacted = .04 - .0055 = .0345 mole
NO₂ formed = 2 x .0345 = .069 moles
equilibrium constant = [ NO₂ ] ² / [ N₂O₄]
= .069² / .0055
= 0.865 .
