Answer:

When considering phase changes, the closer molecules are to one another, the stronger the intermolecular forces. Good! For any given substance, intermolecular forces will be greatest in the solid state and weakest in the gas state.

In the case of melting, added energy is used to break the bonds between the molecules. ... If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.

Why can’t liquids change volume but gases can

natta225 [31]

Explanation:

Liquids cannot change volume but gases can because they have a fixed shape like solids.

Liquids have strong intermolecular forces binding their molecules together resulting is fixed ordering.

Gases are randomized with their molecules haphazardly arranged.
This allows them to expand spontaneously on their own.
Molecules of liquids are more tightly packed compared to gases.
In a liquid, the molecules have a less random pattern of motion and can only slide past one another.
In a gas, the molecules are in continuous random, straight line motion.

bogdanovich [222]

Answer:

The answer to your question is given below

Explanation:

2,4,4,5-tetramethyl-2-hexene.

To draw the structure of the above compound, we must bear the following in mind:

1. The compound is an alkene i.e it contains carbon to carbon double bond (C=C)

2. The parent name of the compound is hexene i.e it contain 6 carbon atoms.

3. The double is located at carbon 2.

4. The substituent group attached to the compound is methly.

5. There are four methly group attached to the compound of which one is located at carbon 2, two at carbon 4 and one at 5.

With the above information, we can easily draw the structure of the compound.

Please see attached photo for the structure of the compound.

One mole of copper equals about how many atoms?

Arlecino [84]

One mole of copper equals 6.02 × 10^23 atoms. The answer is letter C. This follows the Avogaro’s law wherein 1 mole of a substance is equal to 6.02 x 10^23 atoms, formula units or molecules. This is applicable to all substances.
