The elements found in rust are iron and oxygen. Rust has a chemical formula of Fe2O3.Know More
Rusting is a chemical reaction, which refers to a reaction that occurs when one substance turns into something else. Iron starts out as a shiny metal, but if it comes into contact with damp air, it begins to rust. As iron, oxygen and water react, the iron turns from a shiny gray to a dull orange, which makes it easy to determine if rusting has occurred.
The final product of this reaction is ferric oxide, also called iron oxide, which has two atoms of iron for every three atoms of oxygen.Learn more about Solutions & Mixtures
The oxidation reaction of iron and oxygen to form the substance that is commonly called rust occurs according to this equation: 4Fe + 3O2 = 2Fe2O3. Water is also required for this reaction to occur, but because the total amount of water does not change, it is not included in the equation.Full Answer >
The sun is mainly made up of 75 percent hydrogen and 25 percent helium by mass; the sun's is also composed of less than 0.1 percent various metals and elements, including neon, iron, oxygen and carbon. These atoms form hot plasma that is interwoven with the sun´s magnetic fields.Full Answer >
Chemical differentiation describes the process by which heavier, molten elements like iron and nickel sank to the center of the Earth and lighter elements like silicon, oxygen and aluminum populated the surface of the planet 4.5 billion years ago, according to Indiana University-Purdue University Fort Wayne. Scientists theorize that gravity caused the chemical elements to separate into different parts of the Earth.Full Answer >
The Earth's crust is composed of several minerals and elements, including iron, oxygen, silicon, magnesium, sulfur and nickel. Present in smaller amounts are calcium, aluminum and several other elements. The crust is the outermost portion of the Earth, which is comprised of three layers.Full Answer >
