different chemical reactions

Chemical reactions are the processes in which new substances with new properties are formed. A chemical reaction should satisfy the following conditions: There must not be either a gain or loss of matter. There must be either an evolution or an absorption of ..

Summary - Some high fat foods such as potato chips are packaged in materials that protect them from light and oxygen and the containers are flooded with nitrogen to further exclude oxygen At times, to avoid the presence of oxygen altogether, vacuum packaging is used in some processed foodstuff In a..

There are just 26 alphabets in English language, but the number of words are innumerable. You have studied about the 115 known elements and how they are classified for systematic and comprehensive study. Thousands of compounds are born by various chemical reactions involvi..

The electrons thus released move to the zinc rod via the external circuit. The ammonia gas so produced escapes. The hydrogen ions diffuse through the porous pot and interact with MnO 2 . (The charcoal powder makes MnO 2 electrically conducting.) Therefore, These positive charges are giv..

Rates of chemical reaction depends on the inherent characteristics or nature of the reactants. That is the reason, why some reactions are fast while others are slow. For E.g., oxidation of ferrous ion by KMNO 4 (potassium permanganate) in acidic medium is fast, ..

Aldehydes and Ketones are highly reactive compounds. They undergo similar reactions because of the presence of a carbonyl functional group in both of th..

Stoichiometry of Chemical Reactions - A chemical reaction can be represented by a chemical equation, which may be defined as a chemical change in terms of symbols and formulae of the substances involved in the reaction. The subst..
