common chemical compounds

The chemical formula of a compound represents the composition of the molecule of the compound in terms of symbols of the elements present in ..

A cell, a tissue or an organ, which secretes certain useful chemical compounds required for a particular function, is called a Glan..

Introduction - A cell, a tissue or an organ, which secretes certain useful chemical compounds required for a particular function, is called a Glan..

Understanding the Chemical Properties of Acids and Bases - As acids and bases are highly corrosive and reactive substances it is important to understand their reaction and responses on substances commonly found around us. It helps us to understand the outcomes of using them in d..

Types of Chemical Bonding - The type of chemical bond developed between the two combining atoms depends upon the way these atoms acquire a stable noble gas configuration. Elements may combine through any one of the following ways to form stable compounds..

Chemical Properties - Hydrides - Both oxygen and sulphur are very reactive and the reactivity decreases as O > S > Se > Te. Oxygen is very reactive and reacts with almost all elements. Its reactivity is only slightly less than the most reactive elements, halogens. Some of the imp..

Both oxygen and sulphur are very reactive and the reactivity decreases as O > S > Se > Te. Oxygen is very reactive and reacts with almost all elements. Its reactivity is only slightly less than the most reactive elements, halogens. Some of the important compounds of oxygen family..

Introduction - When a chemical reaction gets started the reactants are present in the initial stage, but as the reaction proceeds, the concentration of the reactants decreases and that of products increases. Finally, a stage is reached when no further change in concentration of reactants ..

Introduction - A cell, a tissue or an organ, which secretes certain useful chemical compounds required for a particular function, is called a Gland. Thus glands, which are seretory in functions, can be of two types, namely (i) Exocrine glands that have ducts or the opening for d..

As in the case of S, the important oxidation states observed for Se and Te are also 2, +2, +4 and +6. The chalcogenide dianions (E 2 - ) exist only in their compounds with the most electropositive elements. By and large, chalcogens with the exception of polonium, display non-metall..
