Reduction will occur at cathode In galvanic cell.... There is a short trick tO remember LOAN ( LEFT , OXIDATION, ANODE , NEGATIVE) and baaki ke cathode pr honge ...🙃🙃 ...say me thanks on insta ( sarcast_devil) 😄😄

Reduction happens at the cathode & oxidation happens at the anode, so it is called redox reaction

Haloalkanes dissolve *
as the bond *

1Thank You

Royal Thakur 2 years, 5 months ago

Haloalkane are dissolve in organic
solvent because the bond formed between Haloalkane
and organic solvent has same strength as the being broken

1Thank You

Anjan Karthi 2 years, 5 months ago

Nature of bonds in haloalkanes and organic solvents are the same ie, dipole-dipole interactions. Thus, consequently lesser energy would be required to break the existing bonds between solvents and to form new bonds between solvents and solute. So, easy dissolution. Hope this helps !!!!!

Explain why limiting molar conductance of weak alelctrolytes cannot be determined directly at infinite dilution . How it can be obtained ?

Posted by Chuesha Marak 2 years, 5 months ago

Harsh Mishra 2 years, 4 months ago

It can be obtained only : For example you need to find the limiting molar conductance of CH3COOH So first you need to find the Limiting molar conductance of Strong electrolyte having CH3COO in it i.e CH3COONa-- CH3COO- and Na+ Now find Limiting molar conductance of NaCl- Na+ and Cl- Now find Limiting molar conductance of HCl- H+ and Cl- And add all the reactions You will get LMC of CH3COOH

ANSWER

If a current of 0.5ampere flows through a metallic wire for 2 hours.then how many electrons would flow through the wire

Posted by Bindika Rai 2 years, 5 months ago

CBSE > Class 12 > Chemistry

2 answers

Preeti Dabral 2 years, 5 months ago

We know that current = 0.5 ampere , time= 2h

Q (coulomb) = 1 (ampere) {tex} \times {/tex} t (sec)
= 0.5 ampere {tex} \times 2 \times 60 \times 60{/tex}
= 3600 C
A flow of 1 F, i.e. 96500 C is equivalent to flow of 1 mole of electrons
i.e. {tex}6.023 \times {10^{23}}{/tex} electrons
3600 C is equivalent to flow of electrons {tex} = \frac{{6.02 \times {{10}^{23}}}}{{96500}} \times 3600 = 3.246 \times {10^{22}}{/tex}electrons

I=0.5 t=2h=2×60×60=7200 I=q/t Where Q=ne So I=ne/t 0.5=n×1.6×10*-19/7200 3600×10*22/16 2.25×10*22
