Answer:
If the pressure of the system increases then the boiling point will increase.
If the pressure of the system decreases then the boiling point will decrease. If there is no change in pressure then the boiling point will remain constant.
Explanation:
Reactions of Ethyl-3-pentenoate with all given reagents are given below.
Reaction with H₂ / Pd:
The non-polar double bond present in Ethyl-3-pentenoate is reduced to saturated chain. This reagent can not reduce the carbonyl group.
Reaction with NaBH₄: Sodium Borohydride is a weak reducing agent at compared to LiAlH₄. It can only reduce aldehydes and Ketones to corresponding alcohols.
Reaction with LiAlH₄: Lithium Aluminium hydride is a strong reducing agent. It can reduce all types of carbonyl compounds to corresponding alcohols, But, it can not reduce non-polar double bonds like alkenes and alkynes.
Result: The correct answer is
Option-A (Highlighted RED below).
Answer:
CuSO4 + Fe -> FeSO4 + Cu
Explanation:
This reaction is a classic example of a redox reaction. I won't go in too deep, but the basic thing is that electrons from the Fe atom go to the Cu2+ ion. Therefore, Fe becomes an ion, and Cu - an electroneutral atom:
Fe + Cu2+ -> Fe2+ + Cu.
Silver is not a very reactive metal and it does not give up its electrons to Cu.
The organic compound retinal binds with opsin and forms rhodopsin. Retinal is part of the molecule that is responsible for its color. This part is called chromophore. On the other hand, opsins are the proteins in photoreceptor cells. Retinal bounds with these opsins and forms rhodopsin: the basis of the human vision. Rhodopsin is also a protein.It is the pigment in the retinas of humans and animals.
NH₃, being a basic gas neutralizes the HNO₃ forming a salt NH₄NO₃
Therefore the correct answer is NH₃ and NH₄NO₃
The solution of which only 32% dissociates to release OH⁻ ions is a weak base. This is because some of the energy is used when the substance reacts with the solution thus some bonds are not broken.
HCl is an acid. This is because it dissociates in water to give H⁺ as the only positively charged ions.
Arrhenius acid increases the concentration of hydrogen ions because it dissociates to release hydrogen ions as the only positively charged ions in the acid. So the answer is TRUE
Arrhenius base dissociates in water to release hydroxide ions as the only negatively charged ions.
NaOH⁺aq⇒Na⁺ ₍aq₎+ OH⁻₍aq₎
