Distinguish between residents and citizenship

Posted by Savita Singh 6 years, 8 months ago

CBSE > Class 12 > Economics

1 answers

Yogita Ingle 6 years, 8 months ago

Residency means that a foreign country has allowed you to live and work in that country, usually indefinitely. But, you are still considered to be a foreigner. You may not vote (exceptions do exisit) or stand for elections. You may be deported if you commit a crime. However, children born to you while you are resident in that country are usually citizens by birth.
Citizenship on the other hand is the most complete legal relationship between a person and a country. As a citizen you will have all political rights and you cannot be deported. However, if you are a naturalised citizen, your citizenship may be revoked if you became a citizen by fraud.

Explain . mechanism of micelle formation?

Posted by Priya Priya 6 years, 8 months ago

CBSE > Class 12 > Chemistry

2 answers

Gursharn Kaur 6 years, 7 months ago

Micelle formation works on two turns one is hydrophobic and another one is a hydrophilic hydrophobic molecules are those molecules or we can see a part of molecules which gets repaired one comes in contact with the water molecules and hydrophilic molecules can be defined as the part of a molecules which gets attracted towards the water molecule

1Thank You

Yogita Ingle 6 years, 8 months ago

Mechanism Of Micelle Formation-

Soap is the sodium or potassium salt of fatty acid and may be represented as RCOO^-Na (e.g. sodium stearate, (CH₃(CH₂)16COO^-Na⁺]) . Whendissolved into water , it dissociates into RCOO^- and Na⁺ ions.
The RCOO^-ion consists of two parts – long hydrocarbon chain (also called non – polar tail) which is hydrophobic (water repelling ) and a polar group COO^- (polar head) which is hydrophilic (water loving )

At higher concentrations(CMC) RCOO- ions form an aggregate of spherical shape with the hydrocarbon chains pointing towards the centre and the COO- part facing outward on the surface of the sphere. This aggregate is called ionic micelle. It may have as many as 100 ions
