to tell about WATER water is the most imp thing on earth.without water no life.We take it for granted‚ we waste it‚ and we even pay too much to drink it from little plastic bottles. And still‚ today‚ nearly 1 billion people in the developing world don’t have access to it. Clean‚ safe drinking water is scarce. It is the foundation of life‚ a basic human need. Yet today‚ all around the world‚ far too many people spend their entire day searching for it. Simply put‚ water scarcity is either

Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water molecules

how hydrogen bonding occurs between water molecules‚ and relate this and other properties of water‚ to the roles of water in living organisms. Water is a very small molecule‚ consisting of two hydrogen atoms covalently bonded to an oxygen atom. However the electrons shared are not done so equally‚ oxygen is more electronegative and has a firmer hold on the electrons and pulls them slightly towards its nucleus. Due to this‚ the charge across the molecule of water is not equally distributed‚ and the

Water is the beginning and the continual of life on earth. Because of its many unique properties‚ water was able to start life on our planet. Water covers about 3/4 of the earth. In nature‚ water naturally exists in all three physical states of matter—solid‚ liquid and gas. Water’s extraordinary properties are emergent properties resulting

A 2007 study finds that discharge of untreated sewage is the single most important cause for pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.[1] The majority of the government-owned sewage treatment plants remain closed most of the time due to improper

Water Technology Hardness of Water: Natural waters containing large quantities of dissolved salts of Calcium (Ca) & Magnesium (Mg) is called hard water. It is a characteristic of preventing lather formation of water with soap. Ca2+ & Mg2+ ions react with soaps which are salts of fatty acids (stearic or palmitic acid) to give insoluble scums or precipitates of calcium or magnesium stearate or palmitate. 2C17H35COO- + Ca2+ → (C17H35COO)2 Ca (scum) 2C17H35COO- + Mg2+ → (C17H35COO)2

Water pollution Water pollution is the contamination of water bodies . Mostly water pollution occurs in lakes‚ rivers‚ oceans‚ aquifers and groundwater. Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatmentto remove harmful compounds. Type of water pollutions There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution Some wastewater‚ fertilizers

and soil microbes. In some complex forests‚ there is also a well-defined lower tree layer. Forests are central to all human life because they provide a diverse range of resources: they store carbon‚ aid in regulating the planetary climate‚ purify water and mitigate natural hazards such as floods. Forests also contain roughly 90 percent of the world’s terrestrial biodiversity.[3] ---------------------------------------------------------------------------------------------------------------------
