Answer:
During this reaction electron is transfer from copper to silver.
Explanation:
Ionic equation:
Cu + 2Ag⁺ → Cu²⁺ + 2Ag
Given equation shows that the silver on left hand side is present in the form of cation. The charge on silver is +1 it means one electron is lost by one silver atom. While copper is present in neutral form with oxidation state zero.
Thus copper lose two electron and gain +2 charge these two electrons are accepted by two silver atoms and became neutral.
This equation shows the redox reaction.
Silver gets reduced by gaining the electron and copper gets oxidized by losing the electrons.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.

Explanation:
Hydrolysis is the chemical breakdown of a compound due to reaction with water. It may occur when acid or base is used as the catalyst.
The acid catalyzed hydrolysis of esters is the reverse of esterification. The alcohol and carboxylic acid that combined to form the ester are obtained in the process.
The acid catalyzed of butyl acetate is shown in the image attached.

Given: 2.00 m h2so4 / L
0.250 moles
Solve
To get the volume we need to divide 0.250 moles from 2.00 moles / L
Volume = (0.250 moles)
-----------------------
(2.00 moles/L)
= 0.125 L x 100
= 125 ml
So the answer is 125 milliliters of 2.00 m h2so4 are necessary to provide 0.250 mole of it.
Answer:
Conduction
Explanation:
Conduction seems to be the mechanism whereby heat energy is transferred from adjacent molecules by interactions. In solids and liquids, where even the objects are near to each other, conduction happens more easily than in liquids, where even the molecules are farther separated.
