Cl(g) + H2----> HCl(g) +H
Do interaction can occur at room temperature

Answers

Answer 1

Answer: This is not the proper equation, the equation should be:
Cl2 + H2 ----> 2HCl
This does not happen at room temperature and needs a source of activation energy such a spark.

How many different sets of equivalent protons are there for para-xylene (1,4-dimethylbenzene)? only 1 two three four?

Answers

Answer:

Two

Step-by-step explanation:

There are two ways to determine the number sets of equivalent protons in a compound.

(a) By substitution

Replace each H with a different group and see if you get a different compound

For example, the six CH₃ H atoms are an equivalent set, because, if I replace any one of them, I will always get the same compound: 1-chloromethyl-4-methylbenzene (Fig. 1).

Similarly, the four aromatic H atoms are an equivalent set. If I replace any one of them, I will always get the same compound: 2-chloro-1,4-dimethylbenzene (Fig. 2).

Thus, there are two sets of equivalent protons in p-xylene.

(b) By symmetry

Two atoms are equivalent if one can be converted into the other by a symmetry operation on the molecule.

The methyl hydrogens can be interconverted by a combination of reflections about the AB and CD mirror planes and byrotations about the C-C bonds to the ring (Fig. 3).

Similarly, the four aromatic H atoms can be interconverted by a combination of reflections about the AB and CD mirror planes.

Again, we find two sets of equivalent protons.

Which substance can not be broken down by a chemical reaction?(1) ammonia (3) methane
(2) argon (4) water

Answers

The substance that cannot be broken down by a chemical reaction is argon. This is because the substance is an element, otherwise if this is a compound, then it can be still broken down by chemical means. Ammonia, methane and water are all compounds.

The substance that cannot be broken down by chemical reaction is $\boxed{\left( 2 \right){\text{ argon}}}$ .

Further Explanation:

Substance is the pure form of matter while combination of atoms or molecules is termed as a mixture.

Types of substances:

1. Element

The simplest form of substance that cannot be further broken down by any chemical method is known as an element. Carbon, sulfur, and cobalt are some of the examples of elements.

2. Compound

When two or more different elements are held together by chemical bonds, compounds are formed. These can further be broken down into their respective constituents. Their properties are quite different from those of their constituent elements. NaCl, ${\text{C}}{{\text{H}}_{\text{4}}}$ and ${{\text{H}}_{\text{2}}}{\text{O}}$ are examples of compounds.

(1) Ammonia consists of one nitrogen and three hydrogen atoms so it is a compound. Therefore it can be broken down by chemical reactions.

(2) Argon is an element so it is the simplest form in which it can exist. Therefore it cannot be broken down by chemical reactions.

(3) Methane consists of one carbon and four hydrogen atoms so it a compound. Therefore it can be broken down by chemical reactions.

(4) Water consists of one oxygen and two hydrogen atoms so it is a compound. Therefore it can be broken down by chemical reactions.

How many hydrogen atoms are in the following molecule of ammonium sulfide? (NH4)2Sa. 2
b. 4
c. 8
d. 16

Answers

There are eight hydrogen atoms in the following molecule of ammonium sulfide. Thus, the correct option for this question is C.

What is a Molecule?

A molecule may be defined as a cluster of atoms that are significantly bonded together in order to represent the smallest basic unit of a chemical compound that can involve in a chemical reaction.

According to this question, the correct representation of ammonium sulfide is $(NH_4)_2S$ , where the number of the hydrogen atoms is equal to 4 × 2 = 8. Apart from this, the number of nitrogen atoms is 2. While the number of sulfur atoms is only 1.

Therefore, there are eight hydrogen atoms in the following molecule of ammonium sulfide. Thus, the correct option for this question is C.

The distance between stars is typically measured in

Answers

The distance between stars is typically measured in light years, or the amount of distance traveled by light in one year. This is because stars are extremely far apart, and measuring the distance with a smaller unit of measurement would result in ridiculously large numbers that would be difficult to work with.

Final answer:

The typical measure for the distance between stars is the light-year. Light-year and parsec are units used to quantify the enormous distances in the universe.

Explanation:

The distance between stars is typically measured in light-years. This term, 'light-year', refers to the distance that light can travel in one year, which is approximately 9.461 trillion kilometers or 5.879 trillion miles. Another less commonly used unit is the parsec, which is equivalent to about 3.26 light years. Such large units are necessary due to the vast distances between stars in the universe.

So, The distance between stars is typically measured in light-years.
