The answer will be physical change
Answer:
Answers are given below
Explanation:
(a) Aldehyde groups are reduced by sodium borohydride in methanol to give alcohol.
So, butanal produces butanol on reaction with sodium borohydride in methanol.
(b) Aldehyde forms cyanohydrin when they are treated with HCN with catalytic cyanide.
(c) Aldehydes are oxidized by potassium dichromate in dil. sulphuric acid to produce carboxylic acid.
(d) Aldehyde produces acetal with methanol and a trace amount of acid catalyst.
(e) Aldehyde gives condensation reaction with
to produce imine.
Structures of products for the given reaction has been shown below.
Answer: Radioactive decay
Explanation:
Radioactive decay involves the emission of radiation by the nucleus of an element through the process of disentegration of the nucleus.
The compounds in the reaction that shifts the equilibrium with the common ion effect are
.
<h3>What is the common ion effect?</h3>
The equilibrium condition has an equal amount of reactant and products in the reaction.
The addition of ions same as product or reactant results in a change in the equilibrium of condition and shifts the equilibrium in opposite direction.
The given reaction is:

The addition of sulfate and hydrogen ions shifts the equilibrium.
Thus, the compounds that shift the equilibrium for the reaction are
.
