Choose the compound that exhibits hydrogen bonding as its strongest intermolecular force.

NemiM [27]

Answer:

Explanation:

To form hydrogen bondings between the molecules, the compound needs a highly electronegative atom (usually N, O, or F) bonded with a hydrogen atom;

and that the highly electronegative atom has lone pair outermost shell electrons.

In the 5 options, only B (CH3OH) has an N, O, or F atom that has lone pair outermost shell electrons (2 lone pairs on each O atom), so it can form hydrogen bonds within its molecules.

Hydrogen bonds are stronger than the van der Waals' forces between its molecules (that exist regardless of whether there are hydrogen bonds).

An object starts from rest and exhibits the motion represented by the graph. The object’s average velocity during the 3 second t

Rufina [12.5K]

Answer:

8.4 m/s

Explanation:

Initial velocity of the object is 0 as it was at rest.

We need to find the object’s average velocity during the 3 second to 5 second.

We can see from the graph that from 3 s to 5 s, the graph is a straight line. If we take the slope we can find the average velocity during the 3 second to 5 second.

Displacement between 3 s to 5 s is :

D = 24.8 m - 8 m = 16.8 m

Time = 5 s - 3 s = 2 s

Now,

Average velocity,

$v=\dfrac{\Delta y}{\Delta x}\\\\y=\dfrac{16.8\ m}{2\ m}\\\\y=8.4\ m$

So, the object’s average velocity during the 3 second to 5 second is 8.4 m/s.
