Metals and Non-metals Elements are divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal. Metals: Part - I Physical Properties of Metals:- Hardness:- Most of the metals are hard‚ except alkali metals‚ such as sodium‚ potassium‚ lithium‚ etc. Sodium‚ potassium‚ lithium etc. are very soft metals‚ these can be cut using knife. Strength:- Most of the metals are strong and have high tensile strength. Because of this big structures are made using metals

The article‚ Biotreatment of wastewater using aquatic invertebrates‚ Daphnia magna and Paramecium caudatum‚ mainly pertains to the idea of cleaning dirty‚ polluted water. Every since we‚ as a society‚ have switched from an agrarian to an industrial way of life‚ our waters have become increasingly polluted. Thus‚ scientists have researched conducted experiments in order to attain clean water. One of the failed attempts of attaining clean water was one in which they tried to use chemicals. Unfortunately

molecules. This is due to the scientists‚ who try to bring us from the micro scale to the nano scale‚ though it is another matter in the periodic table that is used‚ Carbon. This leads us to the main issue of this project. Carbon nanotubes describes a specific topic within solid state physics‚ but is also of interest in other sciences like chemistry or biology‚ actually the topic has coating boundaries‚ because we are on the molecule level. The carbon nanotubes have in the recent years become more and more

The Philippine coconut industry is a formidable pillar of the national‚ economic and cultural heritage of the country. It is a source of valuable commodity and a renewable asset‚ vital components to the building of a strong nation. The coconut tree is called the tree of life for its myriad uses to humanity. Coconut Consumption 79% of total production goes to exports and 21% for domestic consumptions. From 1990-1997‚ domestic consumption grew by 3.6% annually‚ while exports grew by an average

Coconut Water Wax A Breakthrough in Fruit Preservation ABSTRACT This study utilized coconut water to produce a wax preservative for fruit and other foodstuff. Different fresh fruits were collected and assigned to four different treatments: * Treatment I (Control): fresh fruits without anything done * Treatment 2: fruits soaked in coconut water for 10 minutes * Treatment 3: fruits covered with coconut water wax * Treatment 4: refrigerated fruits The fruits used were oranges

Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain

This product will be launched in the beverage market to meet the demand of consumers for coconut water which is not being provided by any company in the market although the mobile vendors are providing coconut water to the people to some extent. As mobile vendors are not available everywhere in every time‚ it is easy for any company to skim money from the market by selling bottled coconut water. Moreover‚ coconut water contains promising amount of nutrition which is good for anyone. It can be bottled
