Answer:

They are stronger than hydrogen bonding forces.

Explanation:

A dipole is formed when there is electronegative difference between the two atoms, such that one atom acquires a partial negative charge and the other acquires a partial positive charge. In a hydrogen bond a hydrogen atom is bond to a more electronegative atom. Both dipole-dipole forces and hydrogen are intermolecular forces. However, dipole dipole forces are stronger than hydrogen bonds. Hence option A is correct.

Dipole-dipole forces are stronger than hydrogen bonds. Hence option B is incorrect.

Ion-dipole forces are formed between ions and polar molecules. Hence option C is incorrect.

Dipole-dipole forces occur between atoms hat are bond to each other wherein the atoms have a electronegative difference between them. Hence option D is incorrect.

Which methods are used to construct earthquake resistant buildings?

san4es73 [151]

Answer:

shear walls, cross braces, diaphragms, and moment-resisting frames are central to reinforcing a building. Shear walls are a useful building technology that helps to transfer earthquake forces. Made of panels, these walls help a building keep its shape during movement.

MEASUREMENT AND MATTER Interconverting temperatures in Celsius and Kelvins The metal osmium becomes superconducting at temperatu

nexus9112 [7]

Answer: $-272^0C$ .

Explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like $^0C$ and $K$

These units of temperature are inter convertible.

We are given:

Temperature of the gas = $655mK=0.655K$ (1mK=0.001 K)

Converting this unit of temperature into $^0C$ by using conversion factor:

$(t-273.15)^0C=tK$

$273.15K=0^0C$

Thus $0.655K=(0.655-273.15)^0C=-272^0C$

Thus the temperature is $-272^0C$ .

What is a real-life example of equilibrium and what would happen if there was a shift in the system of that example?

BabaBlast [244]

Answer:

Refrigerator

Explanation:

Think about it. Equilibrium is between 2 "places", and if you didn't open the fridge, there would be a buildup of cold air.

Because of that buildup, it would keep getting colder until it isn't possible to get cold anymore. That is equilibrium.

However, if you were to open the door for a very, very long time, you would lower the temp. inside the fridge, therefore causing for the room you are in to be slightly colder, and the fridge to decrease in cold. The fridge will still be slightly cold, but it won't be lukewarm if you leave it for 2 hours. (Unless it's broken)

That is equilibrium :)
