Answer: Option (a) is the correct answer.

Explanation:

A strong acid is an acid which completely dissociates into its ions in a solution.

For example, HCl is a strong acid and it dissociates as follows.

$HCl \rightleftharpoons H^{+} + Cl^{-}$

Whereas a weak acid dissociates slightly into a solution.

Thus, we can conclude that it is true of a strong acid that it ionizes close to 100 percent in water.

4: The shikimate pathway is critically important and found in plants. Discuss reasons why this pathway is so important and even

Alecsey [184]

Answer:

Explanation:

For the growth and flourishing of animals Aromatic amino acids are very important, but because of lack of shikimate these amino acids are not synthesized in animals pathway.But this pathway is found in both plants and micro organisms and they have the ability to produce these amino acids as well as some secondary metabolites required in animals.

There are different role played by this pathway in organisms such as;

1) It serve as a source of Tryptophan and phenylalanie which are important aromatic amino acid.

2)Neuroactive substances such as serotonin,epinephrine are biosynthesized as result of the product from the pathway.

3)Alkaloids that's found in plants as well as antibiotics possessed by microbes, which are essential therapeutical in animals are secondary metabolites that is biosynthesized as a result of the activities of this product of this pathway.

4)Shikimate is useful in the synthesizing of 6-Fluoroshikimic acid.

5) The shikimate pathway is important for the synthesis of a plethora of aromatic compounds in both plants and bacteria as well as fungi.

There are three sets of sketches below, showing the same pure molecular compound (hydrogen chloride, molecular formula ) at thre

RideAnS [48]

Answer:

The correct answer is - option C.

Explanation:

Given: the melting point of HCl is

-114.8 °C, which suggests that below this temperature HCl will be solid.

and, since the boiling point of HCl is - 85.1 °C. It is also suggested that above this temperature HCl will be gas, Therefore.

Solid -114.8 - Ordered arrangement

Liquid -85.1c - Less orderly arranged

Gaseous - Least orderly arranged

Thus, at —90 °C, HCl will be present 'in the liquid state, At — 1 °C, HCl will be present in the gaseous state and at -129 °C, HCl will be present in the solid-state. So, the molecules will be organized in a more orderly manner .

Thus, the correct answer is - option C
