The reactions of tungsten with CO2 and D2O at high temperatures and low pressures (T >2000 K, 10−5 < P < 10−2Torr) has been studied using mass spectrometry. Under these conditions both reactants produce the same volatile oxide products which result in significant transport of tungsten compared to sublimation. The quasi-equilibrium model of gas surface reactions provides a good qualitative description of the rates of product formation. The fit is quantitatively satisfactory if the JANAF thermochemical values for the products are adjusted within their reported error. A comparison is made between these reactions and the reaction of oxygen with tungsten under similar conditions.
What else can I help you with?
What happens if hot tungsten came into contact with air?
Hot tungsten reacts with the oxygen in the air to form tungsten oxide, which can cause the surface of the tungsten to oxidize and turn black. This reaction results in a thin layer of oxidation on the surface of the tungsten, which can affect its properties and appearance.
What is the solute and solvent of tungsten carbide?
In the context of tungsten carbide, the solute is tungsten carbide itself (the solid compound of tungsten and carbon) and the solvent would be the medium in which tungsten carbide is dissolved, which is typically a liquid like cobalt or nickel in the case of cemented carbide materials.
HOW MUCH DOES 1 LITER OF TUNGSTEN WEIGH?
Tungsten has a density of 19.25 grams per cubic centimeter. Therefore, 1 liter of tungsten would weigh approximately 19.25 kilograms.
What charge would tungsten ion with 68 electrons have?
The charge of an ion is determined by the number of electrons it has gained or lost compared to its neutral state. Tungsten has 74 electrons in its neutral state, so if it has 68 electrons, it has lost 6 electrons and would have a charge of +6.
What is the opposite of reactants?
When a chemical reaction takes place, it starts with chemicals which are called reactants, literally meaning those which react, and after the reaction has taken place you then have chemicals called products, because they were produced by the reaction.
Can tungsten block x-ray?
Yes and no. It is a dense metal but the xrays would react with the molecules in tungsten and that causes more xrays. This reaction is called compton scatter.
What happens if hot tungsten came into contact with air?
Hot tungsten reacts with the oxygen in the air to form tungsten oxide, which can cause the surface of the tungsten to oxidize and turn black. This reaction results in a thin layer of oxidation on the surface of the tungsten, which can affect its properties and appearance.
What is a place that is part of an ocean and partly surrounded by land?
That would be a bay, or inlet.
Would the reaction take place if the reagent were omitted?
It is impossible a reaction without reactants.
What material mould would use for tungsten carbide tips making?
mold for tungsten carbide
How would you speed up a reaction without a catalyst?
heat the vessel the reaction is taking place!
What do you call country that is surrounded by land?
If by "place" you mean a country or state...the term is "landlocked."
What is the solute and solvent of tungsten carbide?
In the context of tungsten carbide, the solute is tungsten carbide itself (the solid compound of tungsten and carbon) and the solvent would be the medium in which tungsten carbide is dissolved, which is typically a liquid like cobalt or nickel in the case of cemented carbide materials.
HOW MUCH DOES 1 LITER OF TUNGSTEN WEIGH?
Tungsten has a density of 19.25 grams per cubic centimeter. Therefore, 1 liter of tungsten would weigh approximately 19.25 kilograms.
What is tungsten's color?
Tungsten has a metallic color similar to that of aluminum.
How strong would diamond mixed tungsten be?
Very strong ANS2: At ordinary conditions of pressure, the temperatures where tungsten melts, carbon would vaporize. That would effectively prevent the crystalline form of carbon {diamond) from forming. Iron becomes harder when alloyed with carbon because it fills in the gaps (interstices) in iron. Since carbon does not form an interstitial alloy with tungsten, it would form pockets or inclusions of carbon in the tungsten and weaken the metal.
If you were suronded in helium would you flote?
by the way you spelt surrounded wrong!!!!!! how would you be surrounded in helium!!!!!!??????????????????
