modern chemistry chapter 7 review chemical formulas and chemical compounds

Remember : A binary compound of an element with nitrogen is called a "nitride". When these nitrides react with hot water, they yield their respective hydroxides and ammoni..

6) Addition of H 2 to C=C bonds of organic compounds to form C-C bonds (catalytic hydrogenation). Catalytic hydrogenation is frequently used in petroleum, plastics and food industries. The conversion of vegetable oil into margarine is an example of catalytic hydrogenation process. One of ..

Ammonia and Ammonium Compounds * By treating excess ammonia with chlorine, ammonium chloride and nitrogen are formed. ..

The noble gases are generally inert and do not participate in the reactions easily. The inertness of noble gases is due to the following reasons. i) The atoms of noble gases have stable closed shell electronic configuration. ii) The noble gases have exceptionally high ionization energies. iii) ..

Chemical Equation - A chemical equation is a "balanced account of a chemical transaction." In any chemical transaction or reaction, the number of atoms of all the participating elements will remain proportionately constant before and after the react..

. In the modern day world, with so many chemical pollutants in the environment, it becomes very essential to study the transformation of these pollutants in the environment. To do this, one needs to have a knowledge of chemical kinetics. The first chemical re..

. The reluctance of silicon to form p p -p p bonds to itself is clearly shown by the following facts: that (i) elemental silicon exists only in tile diamond structure and no form of elemental silicon is comparable to graphite and (ii) while CO 2 is a gas with two carbon oxygen double bonds, SiO 2 i..

Everyday experience tells us that chemical reactions take place in widely varying rates. Infact rates of various reactions vary from very slow to very fast. Some reactions are so rapid that they occur as soon as the reactants are mixed. For example, the reactions involving ionic species ..

Elements, Compounds and Mixtures - According to the chemical classification of matter there are two main categories: Pure substances Mixtur..
