In gaseous particles are slightly lighter than those in pasma which look like liquid
Answer:
Very small cloud droplets of pure water evaporate even when the relative humidity is 100 percent because of the curvature of the droplets surface.
Explanation:
The curvature of a droplet's surface, the molecules present over the surface are much exposed to their surrounding, perhaps less tightly bound by the surface tension force and hence evaporate more speedily than molecules present over the plane surface. For which the saturation vapor pressure of the surface goes up slightly with the curvature of that surface and also with relative humidity. By which the surface is in the equilibrium to more than 100 percent.
Answer:
NaF and KBr
Explanation:
These two substances contain pure ionic bonds. LiI is a covalent compound because of the Large polarizing power of Li and the high polarizability of I(Fajan's rules). The other compounds mentioned are organic compounds. They are not soluble in water at all.
Answer:
C
Explanation:
Nebulization is the process by which a mist of a substance is introduced into a flame so that the free atoms are formed. The free atoms are now introduced into the light path for Atomic Absorption spectrophotometry.
<span>The number of electrons in an atom's outermost valence shell governs its bonding behavior.
In N</span>₂, three electrons are being shared by each nitrogen atom, making a total of 6 shared electrons.
In CCl₄, 4 electrons are being shared by each carbon atom and 1 electron is being shared by each chlorine atom
In SiO₂, 4 electrons are being shared by each silicon atom and 2 electrons are being shared by each oxygen atom.
In AlCl₃, 3 electrons are being shared by each aluminum atom and 1 electron is being shared by each Cl atom
In CaCl₂, 2 electrons are lost by the calcium atom and 1 electron is gained by each chlorine atom
In LiBr, 1 electron is lost by the lithium atom and 1 electron is gained by the bromine atom
