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

molecule of water A chemist’s view of the world is not as narrow as one might think! Yes‚ we start with the atom‚ and then go on to the rules governing the kinds of structural units that can be made from them. We are taught early on to predict the properties of bulk matter from these geometric arrangements. And then we come to H2O‚ and are shocked to find that many of these predictions are way off‚ and that water (and by implication‚ life itself) should not even exist on our planet! But we soon

Solar water disinfection Solar water disinfection is a type of water purification system that uses solar energy in order to make contaminated water safe to drink. This is done by eliminating contagious biological organisms such as bacteria‚ viruses‚ protozoa and worms. This process can only be taken place on biological agents non-biological agents such as toxic chemicals or heavy metals disinfection may not make all kinds of water safe to drink. Therefore additional steps away from disinfection

Goldfish and Water Temperature Goldfish and Water Temperature The subject of my observation is a goldfish that is kept in a 2 gallon fishbowl positioned on a window side table. I have noticed that the goldfish is more active in the earlier morning and later evening than during the afternoon hours. Because the table is near a window that faces northeast‚ the fishbowl receives direct sunlight during the time between eleven o’clock a.m. and four o’clock p.m. The goldfish activity decreases around

While my mom grew up as a devout Christian living a typical suburban life in the Midwest‚ my dad grew up speaking Hebrew‚ practicing Judaism‚ and hiding in bomb shelters during World War II. This might explain why it’s been an ongoing process to figure out who I am and what’s really important to me‚ however over the last few years I have begun to understand my fluid identity. I consider myself a bit of a chameleon. I have a lot of interests‚ ranging

Industrial Water Pollution Control Introduction to industrial water pollution control: When the quality or composition of water changes directly or indirectly as a result of men’s activities such that it becomes unfit for any purpose it is said to be polluted. When a source of pollution can be readily identified because it has a definite source and place where it enters the water is said to come from a point source for example: Municipal and industrial discharge pipes. Organic demanding wastes: organic

Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and they can then be moved

battery my salt water battery has the three main components‚ the electrolyte (in case you didn’t know its like a liquid that conducts th electric current (I hope I spelt that right))‚ a cathode (the negative electrode) and the an anode (the positive electrode). As you may or may not know a chemical reaction must occur so that that chemical energy can be converted into electrical energy which is then used for whatever. In my salt water battery the electric current passes through the salt water which separates
