What reaction would take place if hot tungsten was surrounded by air?

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 charge would tungsten ion with 68 electrons have?
Tungsten has 74 protons. With 68 electrons, it would have a charge of +6.
How can you tell if a chemical reaction has taken place when a hot air balloon flies?
chemical reaction would have taken place because i love u soo much
Would burning of matchstick be a chemical reaction?
yes it will be a chemical reaction..as the head of the match stick is being oxidized to burn. so here the oxidation reaction will take place.
What is the opposite of a reaction releasing energy?
A reaction releasing energy is called an exergonic reaction, so the opposite of the would be a reaction that needs energy to take place, called an endergonic reaction. These are also known as exothermic and endothermic reactions.
Will a reaction take place if Ca H2O?
Yes. The reaction would be Ca + H2O --> Ca(OH)2 + H2. Hope that helped.
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 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 charge would tungsten ion with 68 electrons have?
Tungsten has 74 protons. With 68 electrons, it would have a charge of +6.
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."
When the reaction with potassium had finished what would happen if you added universal indicator solution to the water?
It would turn purple, showing the reaction has taken place.
How can you tell if a chemical reaction has taken place when a hot air balloon flies?
chemical reaction would have taken place because i love u soo much
An environment where an anaerobic reaction takes place would always have?
little to no oxygen
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.
