  2. Dihydrogen monoxide parody - Wikipedia

    en.wikipedia.org/wiki/Dihydrogen_monoxide_parody

    Dihydrogen monoxide is a name for the water molecule, which comprises two hydrogen atoms and one oxygen atom (H 2 O).. The dihydrogen monoxide parody is a parody that involves referring to water by its unfamiliar chemical systematic name "dihydrogen monoxide" (DHMO, or the chemical formula H 2 O) and describing some properties of water in a particularly concerning manner — such as the ...

  3. Iron-oxidizing bacteria - Wikipedia

    en.wikipedia.org/wiki/Iron-oxidizing_bacteria

    The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...

  4. Rust - Wikipedia

    en.wikipedia.org/wiki/Rust

    Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.Rust consists of hydrous iron(III) oxides (Fe 2 O 3 ·nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron.

  5. Anaerobic corrosion - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_corrosion

    Under anoxic conditions, the mechanism for corrosion requires a substitute for oxygen as the oxidizing agent in the redox reaction. [1] For abiotic anaerobic corrosion, that substitute is the hydrogen ion produced in the dissociation of water and the proceeding reduction of the hydrogen ions into diatomic hydrogen gas. [1]

  6. Water damage - Wikipedia

    en.wikipedia.org/wiki/Water_damage

    Water damage can originate by different sources such as a broken dishwasher hose, a washing machine overflow, a dishwasher leakage, broken/leaking pipes, flood waters, groundwater seepage, building envelope failures (leaking roof, windows, doors, siding, etc.) and clogged toilets.

  7. Rusticle - Wikipedia

    en.wikipedia.org/wiki/Rusticle

    A rusticle is a formation of rust similar to an icicle or stalactite in appearance that occurs deep underwater when iron-loving bacteria attack and oxidize wrought iron and steel. They may be familiar from underwater photographs of shipwrecks , such as the RMS Titanic and the German battleship Bismarck .

  8. Calcium Lime Rust - Wikipedia

    en.wikipedia.org/wiki/Calcium_Lime_Rust

    Rust, which is primarily composed of iron oxides (Fe 2 O 3), also reacts with weak acids to form soluble iron salts. The reaction can be simplified as: Fe 2 O 3 + 6H + → 2Fe + 3 + 3H 2 O. In this process, iron ions (Fe + 3) are produced along with water, making the rust easier to remove without causing damage to the underlying metal or ...

  9. Color of water - Wikipedia

    en.wikipedia.org/wiki/Color_of_water

    Reds can be signs of rust from iron pipes or airborne bacteria from lakes, etc. Black water can indicate growth of sulfur-reducing bacteria inside a hot water tank set to too low a temperature. This usually has a strong sulfur or rotten egg (H 2 S) odor and is easily corrected by draining the water heater and increasing the temperature to 49 ...
