ANSWER

how does adsorption of a gas on solid suface vary with temperature

Posted by Reigns Media 6 years, 4 months ago

CBSE > Class 12 > Chemistry

2 answers

Anmol Singh 6 years, 4 months ago

Hi, Adsorption of a gas on a solid (also known as occlusicon) is inversely proportional to the temperature

0Thank You

Yogita Ingle 6 years, 4 months ago

It is observed that the adsorption decreases with the increase of temperature.

For example, one gram of charcoal adsorbs about 10 ml of N2 at 273 K, 20 ml at 244 K and 45 ml at 195 K.

What is co-ordination number?with example.

Posted by Shikha Das 6 years, 4 months ago

CBSE > Class 12 > Chemistry

1 answers

Yogita Ingle 6 years, 4 months ago

The Coordination number of an atom in a given molecule or a crystal refers to the total number of atoms, ion, or molecules bonded to the atom in question. ‘Ligancy’ is another term used to refer to the coordination number of an atom.

The atoms, ions, or molecules that are bonded to the central atom (or molecule/ion) are called ligands. The ligancy of molecules is calculated in a different manner when compared to calculating the coordination number of a central atom in a crystal.

How many moles of cu will be deposited by passing 24125 coulombs of electric current from CuSo4 solution

Posted by Faiz Malik 6 years, 4 months ago

CBSE > Class 12 > Chemistry

Ďãřşháñăã Yadav ? ? ? 6 years, 4 months ago

First write the eq. Cu2+(aq) + 2e- ➡️Cu(s) we know that 1F = 96485 nd also from the eq. we get that there are 2 moles of electrons in the balanced equation ↪️ total coulombs = 2*96485 = 192970C ➡️ now use the formula ➡️ 24125(1 mole of cu/192970) solve this u will get the final answer which is 0.125 mol.

listen sis no need to be depressed organic is easy all u need to understand it's mechanism reasons about catalyst.. Nd for that u have to follow only ncert learn from ncert... Read one chapter approx 2 - 3 times Review your organic chem basics before the class. don't simply mug up.. try to understand it. don’t write mechanism in your short notes, just write down the net reaction and when you revise your short notes just remember mechanism in the back of your mind.

5Thank You

Priya Dharshini ? 6 years, 4 months ago

See... yaar first learn nomenclature and basic conversions.... then do ncert of organic chapter. Read ncert 1 like normally then do it with full concentration. And once again read it. Then solve ncert questions... practise all the name reactions atleast 10 times. Byheart it like hell. If u know that u can do any conversions.... be confident. All are weak in any of the topic dont try to show it in ur papers..
