<span>Generally, a hydrogen bond can be characterized as a proton shared by two lone electron pairs. It occurs when a hydrogen (H) atom, covalently bound to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), experiences the electrostatic field of another highly electronegative atom nearby.
Among the choices in the bond (-N...H-O) one side of the Hydrogen is bonded to a highly electronegative atom with a lone pair (-N) and the other side is directly bonded with a highly electronegative atom (O-).
So -N...H-O- shows a hydrogen bond.</span>
Answer:
Sr
Explanation:
because it's electronegativity is the highest.
50 seconds because 100 divided by to is 50 and if she’s moving 2 meters a second it would take 50 seconds to go 100 meters p.s pls give me branliest
Answer:
The new volume of the gas is 21 L.
Explanation:
Volume of a gas is inversely proportional to its pressure at constant temperature such that,

or

We have,

It is required to find V₂. Using above law or Boyle's law such that :

So, the new volume of the gas is 21 L.
