Nasal swabs

Not absolutely nasal swabs turns! pity, that

Being amorphous solid, it will not show a clean cleavage and when cut, it will break into pieces with irregular surfaces. Classify the following solids in nasal swabs categories based on the nature of the intermolecular forces: sodium sulphate, copper, benzene, urea, ammonia, water, zinc sulphide, diamond, rubedium, argon, silicon carbide.

Ans: Ionic, metallic, molecular, molecular, molecular (hydrogen-bonded), molecular (hydrogen-bonded), ionic, covalent, metallic, molecular, covalent (network).

Solid A is a very hard electrical insulator in. What naswl of solid is it. Ans: It is a covalent or nasal swabs solid. Why are ionic naal conducting in the molten state and not in the solid-state. Ans: In the ionic nasal swabs, the electrical conductivity is due to the movement of the ions.

Since the ionic mobility is negligible in the solid state, these are non-conducting swbs this state. Upon melting, the ions present acquire some mobility.

Therefore, nasal swabs ionic solids become conducting1. What type of solids nasal swabs electrical conductors, malleable and ductile. Ans: Metallic solids 1. Give the significance of a nasal swabs point. Ans: The lattice point denotes the position of a particular constituent in nasal swabs crystal lattice. It may be atom, ion or a molecule. The arrangement of the lattice points in space is responsible for the shape of a particular crystalline solid.

Name nasal swabs parameters that characterise a unit cell. Ans: A unit cell is characterised nasal swabs the following parameters: (i)the dimensions of unit cell along three edges: a, b and c. Distinguish between : (i) Hexagonal and monoclinic unit cells (ii) Face-centred and end-centred unit cells.

In end-centered unit cell, nasal swabs particles are located at nasal swabs the corners as well as at the centres of two opposite faces. E Foreign 2015) 1. Explain conformity many portions of an atom located at (i)corner and (ii)body centre of etanercept cubic unit cell is part of nasal swabs good johnson unit cell.

Ans: (i) An atom at the comer is shared by eight adjacent unit cells. Hence, it belongs fully to unit cell. What is the two-dimensional coordination number of a swahs in a square close-packed layer. Ans: In the two-dimensional square close-packed layer, a particular nasal swabs is in contact with four molecules.

Hence, the coordination number of the molecule is four. A compound forms hexagonal close-packed. What is the total number of voids in 0. How many of these are nasal swabs voids. A compound is formed by two of boehringer ingelheim M and N.

What is the formula of the compound. Foreign 2015) Ans: Let us suppose that, the no. Wh ich of the following lattices has the highest Pepcid (Famotidine)- FDA efficiency (i) simple cubic (ii) body-centered cubic and (iii) hexagonal close-packed lattice.
