Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA

That Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA and

Why are solids rigid. Ans: The constituent particles in solids have fixed positions and can oscillate Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA their mean positions. Hence, they are rigid. Why do solids have definite volume. Ans: Solids keep their volume because of rigidity in their structure. The interparticle forces are very strong.

Moreover, the interparticle spaces tickling feet very few and small as well. As a result, their volumes cannot change by Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA pressure.

Classify the following Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA amorphous or crystalline solids: Polyurethane, naphthalene, benzoic acid, Teflon, potassium nitrate, cellophane, polyvinyl chloride, fibreglass, copper Ans: Crystalline solids: Benzoic acid, potassium nitrate, copper Amorphous solids: Polyurethane, Teflon, cellophane, polyvinyl chloride, fibreglass1.

Why is glass considered as super cooled liquid. Delhi 2013) Ans: Glass is considered to be super cooled liquid because it shows some of the characteristics Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA liquids, though it is an amorphous solid. For example, it is slightly thicker at the bottom. This can be possible only if it has flown like liquid, though very slowly. Refractive Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA of a solid is observed to have the same value along all directions.

Comment on the nature of this solid. Would it show cleavage property. Ans: As the solid has calculate median value of refractive index along all directions, it is isotropic in nature and hence amorphous.

Being amorphous solid, it will not show a clean cleavage and when Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA, it will break into pieces with irregular surfaces.

Classify the following solids in different categories based on the nature of the intermolecular forces: sodium Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA, 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 type of solid is it. Ans: It Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA a covalent or network solid. Why Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA ionic solids conducting in the molten state and not in the solid-state.

Ans: In the ionic solids, 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 in this state. Upon melting, the ions present acquire some mobility. Therefore, the ionic solids become conducting1. What type of solids are electrical conductors, malleable and ductile. Ans: Metallic solids 1. Give the significance Isosorbide Dinitrate and Hydralazine Hcl (BiDil)- FDA a lattice point.

Ans: The lattice point denotes the position of a particular constituent in the crystal lattice. It may be atom, ion or a molecule.
