Answer:

(A) Amine

Explanation:

Ch3Ch2Nh2 is an Amine.

An amine is often a functional group with a lone pair on the nitrogen atom. Amines structurally mimic ammonia, where nitrogen can link with up to three hydrogen atoms. Here the correct option is A.

Amines are organic substances that have a lone pair of nitrogen atoms in them. In essence, they are produced by replacing one or more hydrogen atoms in ammonia (NH₃) with an alkyl or aryl group, giving them the names alkylamines and arylamines, respectively.

In addition to medicines and treatments, amines are used to create nylon and azodyes. They are frequently employed in the creation of compounds for the filtration of water, and medicinal, and crop protection.

Thus the correct option is A.

Using vanable conditions for each test

Explanation:

Answer:

337.5kPa ~ 338kPa

Explanation:

Using the ideal gas law PV=nRT we have the following definitions from the problem:

V(initial) = 20cm³

P(initial) = ?kPa

V(final) = 75cm³

P(final) = 90kPa

Since we know that the number of moles of the sample did not change, nor did the temperature, nor does the ideal gas constant (R) we can rewrite this equation to state:

P(initial)V(initial) = nRT =P(final)V(final) ~  P(initial)V(initial) = P(final)V(final)

Rearranging this equation as we are solving for the initial pressure we find that:

P(initial) = (P(final)V(final))/V(initial)

P(initial) = ((90kPa)(75cm³))/20cm³

P(initial) = 337.5kPa ~ 338kPA

Answer:

the number of crickets in each container

Explanation:

to participate in the experiment you will have to know the crickets in the container

Answer:1) It is due to large cohesive force acting between the molecules of mercury that the droplets of mercury when brought in contact pulled together to form a bigger drop in order to make potential energy minimum. The temperature of this bigger drop increases since the total surface area decreases.  

2) A spherical shape has the minimum surface area to volume ratio of all geometric forms. When two drops of a liquid are brought in contact, the cohesive forces between their molecules coalesce the drops into a single larger drop. This is because, the volume of the liquid remaining the same, the surface area of the resulting single drop is less than the combined surface area of the smaller drops. The resulting decrease in surface energy is released into the environment as heat.

The balanced equation for the chemical equation given in the question above is: 2Cr(s) + 3Cl₂(aq) → 2CrCl₃(s)

The following data were obtained from the question:

Chemical equations are generally balanced by ensuring that the number of atoms of each element present on both sides of the equation are equal.

Now, we shall balance the equation given from the question as follow:

Cr(s) + Cl₂(aq) → CrCl₃(s)

There are 2 atoms of Cl on the left side and 3 atoms on the right side. It can be balanced by writing 2 before CrCl₃ and 3 before Cl₂ as shown below:

Cr(s) + 3Cl₂(aq) → 2CrCl₃(s)

There are 2 atoms of Cr on the right side and 1 atom on the left side. It can be balanced by writing 2 before Cr as shown below:

2Cr(s) + 3Cl₂(aq) → 2CrCl₃(s)

Thus, the equation is balanced.

Answer:

Explanation:

Explanation:

Acetone is captured and cooled.

Substance A is rice, and substance B is sugar.

To separate the components of a mixture the substances to be separated must differ in a given physical property.

In chemistry, there are diverse separation techniques used to separate the components of a mixture. Separation depends on differences in a given physical property such as boiling point, solubility in a solvent, difference in particle size etc.

Filtration can be used to separate a solid from a liquid hence it can be used to separate pulp from orange juice.

To separate water and alcohol, distillation is used because such a separation depends on the difference in the boiling points of water and alcohol. Water boils at a higher temperature than alcohol hence the mixture can be separated by distillation.

Chromatography is a method of separation that is dependent on how quickly a the components of a  mixture move through a stationary phase.

Acetone has a lower boiling point than water hence it collected first and cooled before water.

Clearly, substance A must be a solid since it is filtered out after adding water. Substance B must be a water soluble substance which can be recovered from water by evaporation to dryness. Hence substance A is rice, and substance B is sugar.

The correct answer is; Carbon atoms can form chains and branches with each other, and other atoms can attach to these.

Organic chemistry is regarded as the chemistry of carbon compounds and carbon atoms are known to catenate.

Organic chemistry is the branch of chemistry that studies carbon compounds. There are thousands of organic compounds in existence.

The common thread that joins all these organic compounds is that they all contain a long or branched chain of carbon atoms linked to each other. This ability of carbon atoms to self-link forming long chains or branches or macrocyclic compounds is called catenation.

The long or branched chain of carbon is therefore the "back bone" or main framework of the compound.
