Answer:
D
Explanation:
It is also known as the Dalton’s law of partial pressure. Given a confinement that contains a mixture of gases which do not mix, the total pressure equals the sum of the individual pressures.
The term, which do not mix is necessary because, if the gases are the type that mix, the law will no longer hold as they would have given up their individual identities and hence their individual partial pressure cannot be use to access them anymore.
Hence, the law helps to sum the totality of the pressures of a number of gases which exists together in a confinement and they do not mix. Say we have 3 gases A, B and C. The total pressure is the sum of pressure A, pressure B and pressure C.
A wave.
Scientists now recognize that light can behave as both a particle and a wave.

Duhhhh
The two properties of most non metals are high ionization energy and poor electrical conductivity. The correct option among all the options that are given in the question is option "1".
In general it is known that nonmetals are very poor
conductors of heat and electricity. The nonmetals that are solid are normally
very brittle and has very little or no metallic luster at all. Nonmetals are
highly reactive and show variety of chemical properties. It can also be pointed
out that the nonmetals gain electrons very easily.
