Montano1993 [528]

Answer: HF-dipole- dipole interaction

CH3OH- dipole-dipole interaction

CaCl2- ion-ion interaction

Explanation:

Both CH3OH and HF possess permanent dipoles which interact with water leading to the dissolution of the above named substances. Remember that water also possesses a permanent dipole. Which can interact with the dipoles on other polar molecules. CaCl2 is purely ionic and interacts with water via ion-dipole mechanism.

What are Newton's three laws of motion? Are they correct?​
muminat

Answer:

Explanation:

Of course Newton's three laws of motion are correct, because they were verified several hundred of years ago and they continue working today, for such systems. Science is accumulative. What modern physics has done is to constraint the range of validity of those laws.

Newtons first law of motion states that everybody continues in it rest or of uniform motion in a straight line unless an external force is applied on it.

Newtons second law of motion states that acceleration produced on a body by a force is directly proportional to the applied force and inversely proportional to the mass of body.

Newtons third law of motion states that to every action there is equal and opposite reaction.

Hope it will be helpful :)
