Elevated temperature, immersion in a humid and oxygen rich environment, contact with a metal that is lower in the electrochemical series, and mechanical agitation are conditions that cause an iron nail to rust faster. Ru... More »

Rust is caused when iron comes into direct contact with water and oxygen. Technically, rust comes from a chemical reaction between carbon dioxide from the air, water and the iron. Rusting is an oxidation reaction. More »

Iron can be found in the Earth's core, in the Earth's crust, in hemoglobin, in steel and in magnets. It is rare to find iron in its elemental form on Earth, but it has been found in igneous rocks in Russia. More »

Chrome does rust, because it is a metal that readily interacts with moisture and oxygen. Chrome is formed by electroplating a metal with the element chromium, which has greater corrosion resistance than most other metals... More »

Iron rusts when it comes in contact with oxygen and water. It rusts faster in acid rain and salty water. Both oxygen and water are necessary for rusting, which is an oxidation reaction. More »

According to the acid-base tutorial from Tulane University Department of Anesthesia, standard bicarbonate is the bicarbonate concentration under standard conditions of 40 mmHg pCO2, temperature of 37 degrees Celsius and ... More »
