The correct answer is 0.04287 M
It is given that the rate constant of the reaction is 6.2 × 10⁻⁵ mol/L/s
Thus, as the rate of the reaction is in mol/L/s, it is a zero order reaction.
The initial concentration of a is 0.0500 M, and there is a need to find the concentration of a after 115 seconds. This can be done with the help of the equation:
[A]o -[A] = kt
[A] = [A]o - kt
= (0.0500 M) - (6.2 × 10⁻⁵) (115 s)
= 0.04287 M
The standard Gibbs free energy of formation of ZnO from Zn is lower than that of CO2 from CO. Therefore, CO cannot reduce ZnO to Zn. Hence, Zn is not extracted from ZnO through reduction using CO
I don’t understand wha u just said but thanks for the points
Answer:
Polarity is a measure of molecule's electrical charge which means that molecule or it's groups can have a dipole moment and also make hydrogen bonds.
Explanation:
So in terms of polarity methanol is more polar then ethyl acetate due to it's higher dipole moment and that it is a stronger hydrogen bond acceptor and also can be a hydrogen bond donor. So if we add methanol to the elutioning system it becomes more polar because and our compound moves faster on tlc due to methanol providing some more hydrogen bonds to it and increasing dipole-dipole interactions.
