Answer:

The correct appropriate will be Option 1 (Acid anhydrides are less stable than esters so the equilibrium favors the ester product.)

Explanation:

  • Acid anhydride, instead of just a carboxyl group, is typically favored for esterification. The predominant theory would be that Anhydride acid is somewhat more volatile than acid. This is favored equilibrium changes more toward the right of the whole ester structure.
  • Extremely responsive than carboxylic acid become acid anhydride as well as acyl chloride. Thus, for esterification, individuals were most favored.

The other options offered are not relevant to something like the scenario presented. So, the solution here is just the right one.

How do plants and animals differ in how they get food?​
Vilka [71]
Animals get their food by preying on other species or scrounging for scraps they can find. Some eat other animals and some eat plants.
Plants get their food by absorbing minerals and water from the ground and absorbing carbon dioxide from the air through their leaves. They then also absorb sunlight and all of those components are made into food for the plant. Simple answer is through photosynthesis.

PbO2 + 4HCl --- PbCl2 + Cl2 + 2H2O who buys electrons and who loses electrons?​
SIZIF [17.4K]

<u>Answer:</u> Electrons are taken up by PbO_2 and they are lost by HCl

<u>Explanation:</u>

Redox reaction is defined as the reaction in which oxidation and reduction take place simultaneously. It is also called the reaction where the exchange of electrons takes place.

An oxidation reaction is defined as the reaction in which a chemical species loses electrons takes place. In this reaction, the oxidation state of a substance gets increased.

A reduction reaction is defined as the reaction in which a chemical species gains electrons takes place. In this reaction, the oxidation state of a substance gets reduced.

For the given chemical reaction:

PbO_2+4HCl\rightarrow PbCl_2+Cl_2+2H_2O

The half-reactions for this redox rection follows:

<u>Oxidation half-reaction:</u>  2HCl\rightarrow ClO_2 + 2e^-

<u>Reduction half-reaction:</u>  PbO_2+2e^-\rightarrow PbCl_2

Hence, electrons are taken up by PbO_2 and they are lost by HCl
