WATER CYCLE Water Cycle‚ also known as hydrologic cycle‚ is a process that is constantly recycling the Earth ’s supply of water. This is important because humans‚ animals‚ and plants all need water to survive. It is controlled by the sun‚ which produces energy in the form of heat. This heat energy causes the water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called

Oxygen Cycle Required for Life All living things use oxygen or depend on organisms that use oxygen in some way. All Animals and Other Consumers Use Oxygen We use oxygen to break down simple sugar and release energy. This can be done through respiration or fermentation. Animals mainly use respiration. Respiration The process that breaks apart simple food molecules to release energy. It occurs inside cells. What YOU do with the oxygen

What does it mean to be an American today? This is a very difficult question to answer‚ but I believe that it is not just an academic question. As our society becomes more diverse‚ America will develop a broader and richer culture. At the same time‚ nations depend upon some sort of core values‚ beliefs‚ and identity to cling to.

reaction‚ the magnesium will dissolve in the hydrochloric acid to produce hydrogen gas. This is because magnesium is higher than hydrogen in the reactivity series. Therefore‚ when the two reactants are combined‚ a displacement reaction occus and the magnesium displaces the hydrogen‚ forming magnesium chloride and hydrogen gas. Mg (s) + 2HCl (aq) -> MgCl 2 (aq) + H 2 (g) Magnesium + Hydrochloric acid -> Magnesium Chloride + Hydrogen Aim The aim of this investigation

Acid in the human stomach When people refer to acid they usually see it as a corrosive liquid that can dissolve metals or change the color of a substance. So they think of acid as a dangerous matter for the body and believe it can easily dissolve your skin. What I have previously listed are indeed properties of certain acids‚ such as Hydrofluoric Acid which can cause irreversible tissue damage if it comes in contact with skin‚ but not all acids are this strong. As a matter of fact what a lot of

ETHERS Classification of Ethers: Symmetrical ethers – two groups attached to O are identical Ex. CH3CH2OCH2CH3 – diethyl ether Unsymmetrical ethers – two groups attached to O are not identical Ex. CH3CH2OCH3 – ethyl methyl ether Physical Properties of Ethers: Ethers have much lower boiling points compared to alcohols of comparable MWs. BPs of ethers increases with increasing MW. BPs of isomeric ethers increase with increasing alkyl chain length. BPs of ethers are about the

What It Means To Be an Australian Australia is a very unique place‚ along with our multiculturalism there is also a strong heritage surrounding us. At first thought of Australian heritage we think about such landmarks as Uluru‚ The Sydney harbour bridge and The Sydney opera house‚ The Great Barrier reef and other internationally recognised places. But our heritage goes much deeper than that; it is far more than outstanding icons. Along with these icons there are also unsung places like the
