conclusion for classification of matter

In this chapter we have understood the conversion of electrical energy into chemical energy and vice versa. It deals with interactions of matter and electricity. We have learnt about the various applications of electro chemistry which goes a long way in helping mankind to make his life mo..

Since all gases form cathode rays, it means that all atoms contain electrons. As the cathode ray particles were negatively charged, an electron was also carried a negative charge. The following processes were also found to emit electrons: a) The action of heat on certain metals. b) The action of ul..

Take a look at your surroundings. You may find a pencil, a book, an apple, a table or a chair. Can you feel the air blowing? These are different forms of matter. One or more of our senses can recognize these. These objects possess mass, occupy space and have different shapes, sizes and c..

Presence of dangerous unnatural ingredeints causing imbalance in the ecosystems and health hazards to human beings and animals is called pollutio..

Respiration is an important process in nature. It is a process by which the solar energy trapped by the plants in the food can be utilised. The organic compounds are broken down to release energy. This energy is in the form of ATP molecules and is made available for all the vital activities o..

Since all gases form cathode rays, it means that all atoms contain electrons. The cathode ray particles being negatively charged an electron is negatively charge..

In this chapter on chemical bonding, we have learnt the meaning of chemical bonding, need for bonding, and the different types of chemical bonding: ionic, covalent, polar covalent and coordinate bondin..

Currently, 106 elements are known to the human kind. The number of carbon compounds alone is much more than the number of compounds of all remaining 105 elements put together. The number of carbon compounds known to man is around 600,000 whereas the number of the compounds of all the remainin..

Rate of reaction usually doubles when the temperature is raised by ten degrees near the normal temperature because the rate constant is dependent on temperature. The temperature dependency of rate constant is mathematically expressed by the Arrhenius equation. Arrhenius equation is an empiric..

Transition elements are known for their ability to form many complex compounds. The complex compounds in which the metallic ion is surrounded by two or more ions or molecules are called coordination compounds, also known as complex compounds. The chapter has covered the nomenclature, isomeris..
