Mixture E consists of two esters X with two functions, Y with three functions in open circuit (MX < My). Complete combustion

of mg of E yields 0.3 mol CO2 and 0.24 mol H2O. On the other hand, complete hydrolysis of milligram E with NaOH solution yields 3.48 grams of a mixture of two alcohols and a salt mixture of two carboxylic acids. Burning all two alcohols requires 0.1575mol 0 , yielding 0.12 mol CO2 . Find the percent by mass of Y in E.​

The reaction AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq) is a(n) ______________ reaction.
Temka [501]

Answer : The correct option is, (e) precipitation reaction

Explanation :

Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Precipitation reaction : It is defined as the reaction in which an insoluble salt formed when two aqueous solutions are combined.

The insoluble salt that settle down in the solution is known an precipitate.

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

A+BC\rightarrow AC+B

In this reaction, A is more reactive element and B is less reactive element.

Acid-base reaction : It is defined as the reaction in which an acid react with a base to give salt and water as a product.

The given chemical reaction is:

AgNO_3(aq)+NaCl(aq)\rightarrow AgCl(s)+NaNO_3(aq)

This reaction is a precipitation reaction in which the two aqueous solution silver nitrate and sodium chloride combined to give sodium nitrate solution and silver chloride as a precipitate. In precipitation reaction there is no changes in oxidation state of the element.

Hence, the correct option is, (e) precipitation
