=Rust= 4Fe + 3O2 = 2FeO3




 * Iron**

Iron, or Fe, is the most common element in the Earth's crust. It can often be found in meteorites and in other low oxygen environments. This is because iron is highly reactive to both oxygen and water. Newly formed iron appears as a silver, gray metal, but quickly turns orange in the Earth's atmosphere. Pure iron is a soft metal, but almost unobtainable due to the impurities gained during the smelting process. Iron is an important metal in biology for it is capable of forming highly complex bonds with the oxygen in sugars and transports it as well as proteins throughout invertebrates. Iron is also the metal used at the active site of many important redox enzymes dealing with cellular respiration and oxidation and reduction in plants and animals.


 * Oxygen**

Oxygen, represented by the letter O, is a non-metal element that easily forms compounds with many other elements.This is due to it's high reactivity. After flourine, oxygen has the second highest electronegativity of all the elements. Oxygen on it's own makes up over half the Earth's crust.Oxygen was discovered in 1774 by Joseph Priestly, however the name term oxygen was later coined in 1777 by Antoine Lavoisier. The chemical formula of oxygen is O2, in which two oxygen atoms are bonded to one another in a double bond.

Every year, the rusting of buildings, bridges and other structures cost the government and therefore the tax payers, thousands of dollars. Rust has a much greater volume than the iron that is was made from and because of that, rust build-up can cause adjacent parts to be forced apart. This phenomenon is often referred to as "rust smacking," and is the cause of the collapse of the Mianus river bridge in 1983. In this case, the internal bearings rusted to such an extent as to push one corner of the road slab off of its support. Rust was also the cause of the Silver Bridge disaster of 1967, when a suspension bridge made of steal collapsed and killed 46 commuters in under a minute.
 * The Significance of Rust**


 * Conclusion**

Chemical reactions clearly hold a vast significance in our everyday life. Without chemical reactions, we would have no plants because plants frequently utilize the photosynthesis process. The photosynthesis process just happens to be a chemical reaction. We consume plants, and we also consume the animals that live off of plants. Therefore, without chemical reactions we would have no food. Without food we would die. The products of chemical reactions also make up the Earth we live on. Without chemical reactions, we would lack a planet. And again, there would be no human life.
