To prevent this, chromium is added, and the product is called stainless steel. Chromium reacts with oxygen and moisture to develop a layer of chromium oxide over the steel surface, preventing rust from damaging it. To classify any steel as “stainless steel” it must contain a minimum of 10...
In the formation of acid rain, sulfur dioxide reacts with oxygen and water in the air to form sulfuric acid. Write a balanced chemical equation for the reaction. Using nitric acid, how can phosphoric acid be obtained in one step? State the conditions of the reaction and...
Nickel-metal hydride batteries work in a very similar way, although with a bigger capacity. While not as strictly regulated as lithium batteries, there are still guidelines to follow when shipping dry cell and nickel-metal hydride batteries internationally. Pack batteries inside devices (if ...
The main reason for not wearing stainless steel bracelets and jewelry in a swimming pool is that the chlorine can break down the surface layer of the metal. It’s the chromium in stainless steel that reacts with oxygen and forms a thin, invisible layer of chromium oxide over the surface. ...
Alkanes are hydrocarbons, which means they contain only carbon and hydrogen atoms. As saturated hydrocarbons, alkanes contain hydrogen in every available place. This makes them fairly non-responsive, apart from when they react to and with oxygen in the air (called burning or combustion). Alkanes ...
After the electrolysis process kicks in, some of the hydrogen reacts with the accumulating CO2. A byproduct of this interaction is methane gas, which gets vented into space. Meanwhile, reclaimed oxygen enters the ISS air supply [source: Starr]. While that's going on, drinking water gets ...
What does 'elements made up of atoms with the same number of protons' mean? How can we tell how atoms react with each other by looking at the periodic table and how can we tell if an electron has been removed or added from an atom?
The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp ...
How peroxide and ammonia react with your hair is directly related to the level and kind of product you're using. Here are basic descriptions of the three major hair coloring product levels used by Clairol, L'oreal and others: Level 1, semi-permanent color -- This product adds color ...
However, it comes with a high energy cost, and can cause dye bleed and color leaching on dyed parts. Mid-temperature sealing Less energy-intensive than hot sealing, this method uses metal salts in solution, such as salts of nickel, magnesium or cobalt, to react with the surface and fill...
