Posted by Aarti Garg 5 years, 9 months ago

CBSE > Class 09 > Science

1 answers

Neha Passi 5 years, 9 months ago

Atomic number of chlorine is 17 For finding valency, divide the electrons according to the shells K shell= 2[filled using 2n² ( 2*1²) formula where n is the orbit no. or energy index, 1,2,3,4] L shell= 8(2*2² and filled too) M shell= 7(Not filled as there are no more electrons left) It's valency will be 1 using the octet rule which says that in the last shell there should atleast be 8 electrons for the atom to be stable.

Dalton low

Posted by Harsh Maurya 5 years, 10 months ago

CBSE > Class 09 > Science

1 answers

Yogita Ingle 5 years, 9 months ago

The relation between the pressures of the mixture of non-reacting gases enclosed in a vessel to their individual pressure is described in the law.
The law was given by John Dalton in 1807.
It states that.
At constant temperature, the pressure exerted by a mixture of two or more non-reacting gases enclosed in a definite volume, is equal to the sum of the individual pressures which each gas would exert if present alone in the same volume.
The individual pressures of gases are known as partial pressures.
Mathematically
If P is the total pressure of the mixture of non-reacting gases at temperature T and volume V, and P1, P2, P3 …. represent the partial pressures of the gases, then P = P1 + P2 + P3+ ……… (T, V are constant)
