i) Nylons are insoluble in common solvents, have good strength and absorb little moisture. ii) It is used for tyre cords, fabrics, ropes, carpets and manufacture of garmen..

. Millions of Indians live in hopes of good governance that will meet their basic expectations. But the system itself is rotten and collapsing. It is corrupt and inefficient and the only force that holds up its creaking timbers is an overwhelming arrogance that is for me the most detestab..

Certain flowering plants have the capacity to develop a part of their somatic body into a new independent plant. In artificial vegetative propagation, such plants are identified and special techniques are applied to obtain new independent plant. Horticulture have used the various methods of vegetat..

Sodium chloride is the commonly available salt and so is called common salt. Seawater is the main source of sodium chloride. Seawater contains about 3.5% of soluble salts, the most common of which is sodium chloride (2.7 to 2.9%). Saline water of inland lakes is also ..

To calculate the volume of a definite solution required to prepare solutions of other normality, the following equation is used: N 1 V 1 =N 2 V 2 , where N 1 =initial normality and N 2 =normality of the new solution, a nd V 1 = initial volume and V 2 = volume of the new solution. The normality equa..

Normality Equation - To calculate the volume of a definite solution required to prepare solutions of other normality, the following equation is used: N 1 V 1 =N 2 V 2 , where N 1 =initial normality and N 2 =normality of the new solution, a nd V 1 = initial volume and V 2 = volume of the new solutio..

In metallic crystals the constituent particles are positive kernels i.e., nuclei where inner electrons are dispersed in a sea of mobile valence electrons. The forces present between the constituents are metallic bonds. The main characteristics of metallic crystals are: Metallic crystals may be ha..

Characteristics of Sources of Energy - A good source of energy should have the following characteristics: It should do a large amount of work per unit mass or volume - it means that the output energy must be more than the input energy. It should have high calorific value. It should be eas..

Acids, bases and salts are three main categories of chemical compounds. These have certain definite properties which distinguish one class from the other. The sour taste of many fruits and vegetables, lemon for instance, is due to various types of acids present in them. The digestive fluids of mos..
