Explain the three states of matter on the basis of characteristics of particles/ molecules of matter.

Answer :

Explanation For The Three States OF Matter On the Basis OF Characteristics Of Particles / Molecules OF Matter.

<h3>Solid: </h3>

In solids the molecules are closely packed . There is a strong force of attraction between the molecules and the space between them is very small (almost negligible). The molecules are , therefore, not free to move . They merely vibrate their mean positions . This makes solids hard and difficult to compress , giving them a fixed shape and size.

<h3>Liquid : </h3>

In the case of liquids , the molecules are not closely packed. They do not attract each other as strongly as the molecules of solids. Thus, the intermolecular spaces are larger and the molecules are able to move about more freely . This makes liquid flow and take the shape of the container into which it is poured. Thus, liquids have a fixed volume but no definite shape of their own .

In the case of gases, the molecules hardly attract each other. They lie far a part from each other and the intermolecular spaces are, therefore, very large. . The intermolecular force of attraction is so weak that the molecules have great freedom of movement . As a result , gases have neither a fixed shapenor a fixed volume . They completely full up spacw available to them. They can be easily compressed as well, thus decreasing the gaps between their molecules .

1.) Silicon carbide is another network solid with an extensively interlocked structure. Silicon and carbon are capable of sharin

wolverine [178]

1. Silicon is in the same group and also has 4 valence electrons.
2. covalent
3. 1
4. Wood
6. 1s22s22p2
7. Covalent

Those questions were somewhat simple. Questions #5 and #8 I'm not certain of and if you have any kind of textbook or course material, it'd be beneficial to look at it. I hope you were able to figure out the answer to Question #4 was "Wood", otherwise your teacher must be slacking :P. I'll try to figure out the answers to #5 and #8 and let you know what I figured out.

Draw the curved arrow mechanism for the formation of an acetal from acidic methanol and 4-methylpentan-2-one in the fewest steps

morpeh [17]

Answer:

See explanation below

Explanation:

This reaction is known as Ketone hydrolisis in acid medium. This involves the formation of an hemi cetal, and then, the acetal. This is often used to convert ketones or aldehydes in ethers.

The first step involves the reaction with the acid. The carbonile reacts with the acid and forms an alcohol there. The next step is the reaction of the alcohol, in this case, the methanol to form the hemi cetal. Then in the third step, we repeat the first step, using acid to turn the OH group into a great leaving group such water. Then the water leaves the molecule, leaving the space wide open in the next step for methanol, and the acetal is formed.

See picture for the curved arrow mechanism

What are the products formed when ethane burns in excess oxygen?

Neporo4naja [7]

2 C2H6 + 7 O2 -> 4CO2 + 6 H2O
so the products are carbondioxide & water vapour
