Tungsten carbide is a metallic chemical compound. Unlike steel, it is not a mixture or alloy. The chemical formula for tungsten carbide is WC, indicating that the number of atoms of tungsten (W) in a sample of tungsten carbide is equal to the number of number of atoms of carbon (C) in that sample. Because each atom of tungsten weighs about 15.3 times as much as each atom of carbon, almost 94% of the mass of a sample of tungsten carbide is represented by tungsten atoms. Although tungsten carbide is not itself a mixture, it is often mixed (alloyed) with other metals such as nickel or cobalt.
No you cannot because copper is an extremely well conductor, which implies that energy would simply follow through the copper without dissipating much energy, it would not light up.
Tungsten jewelry is usually shiny. Tungsten remains shiny much longer than other metals due to its resistance to scratching and damage.
Halogen light bulbs are used because:they can be operated at a higher temperature than can be used for ordinary light bulbs. This results in less heat production compared to light output and an overall much higher efficiency in the conversion of the energy which is input - electrical energy - to the energy which is output as visible light.andthey have a significantly longer useful life than ordinary incandescent light bulbs.Technical noteThe invention of halogen lamps was based on the discovery of a special physical feature: when small amounts of a halogen gas were added to the contents of the light bulb, these were found to help to return large quantities of evaporated tungsten atoms back to the filament. This resulted in a significantly longer lifetime of such lamps.General note about how all incandescent filament light bulbs operateAn electrical current travelling through the filament of a light bulb makes it glow white-hot and generate both light and heat because of the electrical resistance of the filament.The filament is normally mounted within a special mixture of noble and/or inert gases held inside the glass enclosure of the light bulb, held at a pressure which is close to a vacuum.The special mixture of gases prevents the filament from oxidizing and burning away, which would happen extremely quickly if it glowed white-hot in normal air which contains oxygen.
Tungsten is an element with the symbol W, not a compound so no. It should be Ammonium Pernitrate. By the way, it's not very common which is why there's not much mention on it. Just refrain from calling it Ammonium tetranitrate etc like many people do.
This is like asking 'how much tungsten do I have?' Perhaps you are asking about density or some other property of tungsten.
how much the 1 gramm tungsten
Tungsten costs $35 for one kilo.
No. Tungsten is an element, where as tungsten carbide is an alloy, or a mixture of elements (tungsten, nickel, tantalum, niobium, titanium, and chromium). Tungsten carbide is much easier to work into styles and designs, but does not change the hardness of the metal.
