Helium is a chemical element with the atomic number 2 and the letter He. It is a colourless, odourless, tasteless, non-toxic, inert, monatomic gas and the first member of the noble gas group in the periodic chartIt has the lowest melting and boiling points of all the elements.

Since helium is a safe, non-flammable gas, it is frequently used to inflate balloons for festivities and parades. On the other hand, helium is a crucial component in several sectors, including high-tech manufacturing, medical technology, space exploration, and national security.

The second most prevalent element in the universe, helium, is scarce on Earth. It is the lightest noble gas, colourless, odourless, inert, and has a low boiling point. It is a byproduct of nuclear fusion and radioactive decay.

According to Boyle's Law:

P₁ V₁=P₂ V₂

P₁=1.61atm

V₁=2.26L

V₂=4.12L

P₂=(P₁ V₁)/V₂

P₂=((1.61atm)(2.26L))/4.12L

P₂=0.636atm

Boyle's Law states that the volume of a given quantity of gas at a constant temperature is inversely proportional to its pressure, so this makes sense. The pressure must decrease proportionally as the volume rises.

The product can be made optically active by its enantiomers.

Let us understand the reaction.

If the totaling of bromine to cis-cinnamic acid uses the same mechanism or device as the addition to trans-cinnamic acid, addition of bromine only transpires on the top (syn) and not the bottommost face (anti).

So, bromine added to cis-cinnamic only adds to the same face (syn addition) as a result producing only three dibromides. These three dibromides can be kept on different positions which forms enantiomers.

We trans-cinnamic acid with bromine to form 2,3-dibromo-3- phenylpropanoic acid.

Answer:

A conjugate acid is the product that is different from a base by one proton.

Explanation:

What is a conjugate acid Example?

A conjugate acid is the product that is different from a base by one proton. Examples of conjugate acids include water (base) reacting with an acid to form the hydronium ion (conjugate acid), and ammonia (base) reacting with an acid to form the ammonium ion (conjugate acid).

The conjugate of HF:

So as we know, a conjugate base is simply an acid that has given up a proton. In the case of HF (hydrofluoric acid), once it donates the H+ ion/proton, it becomes F- (fluoride ion). The remaining F- is the conjugate base of HF and conversely, HF is the conjugate acid of F-.

The conjugate of HCL:

If a species is classified as a strong acid, its conjugate base will be weak.[3] An example of this case would be the dissociation of hydrochloric acid HCl in water. Since HCl is a strong acid (it dissociates to a great extent), its conjugate base (Cl−) will be a weak conjugate base. Therefore, in this system, most H+ will be in the form of a hydronium ion H3O+

instead of attached to a Cl− anion and the conjugate base will be weaker than a water molecule.

Conjugate base of HCl in the following reaction is: HCl(aq)+H2O→Cl−(aq)+H3O+.

The conjugate of NH:

Normally the conjugate acid of a weak base is a strong acid, however, the conjugate acid of the weak base NH3 is a weak acid, NH4+.A conjugate acid-base pair is an acid-base pair that differs only by one proton.Conjugate acid When a proton is added to a base, a conjugate acid is formed.Conjugate acids have one extra proton compared to the species that is forming it.Conjugate acid of NH3.The given species is ammoniaNH3.The conjugate acid of NH3 is NH4+.
