1. which can happen during a physical change? (2 points)
molecules can move more rapidly and freely and change states.
the molecules in a substance break into smaller molecules.
the molecules in a substance react with other molecules.
the molecules in a substance are destroyed.

I believe the correct answer from the choices listed above is the first option. During a physical change, molecules can move more rapidly and freely and change states. Such action, would not disrupt or destroy the nature of the molecules they will still have  the same molecular structure. Hope this answers the question.

Answer : The correct option is, Molecules can move more rapidly and freely and change states.

Explanation :

Physical change : It is a change in which there is no new compound or substance formed, only changes occurs in the phase or states.Chemical change : It is a change in which a new compound or substance is formed and also some energy releases. There is no changes occurs in the phase or states.

Molecules can move more rapidly and freely and change states.  

In this process, a physical change occurs due to the changes in the phase.

The molecules in a substance break into smaller molecules.

In this process, a chemical change occurs due to the formation of new compound.

The molecules in a substance react with other molecules.

In this process, a chemical change occurs because when a molecule react with another molecule it gives new compound.

The molecules in a substance are destroyed.

In this process, a chemical change occurs due to the decomposition of molecule to give a new compound.

Hence, the correct option is, Molecules can move more rapidly and freely and change states.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
