What is the Chemical name of this?
thanx in advance!
hope you have an answer of this question. . .
Answer:
That would be carbon black.
Carbon black is the term used to describe a group of intensely black, finely divided forms of amorphous carbon, which can form as soot when fuels (like gasoline, diesel fuel and coal) are not completely burned. Like in the porcelain dish when you put it on the flame of the Bunsen Burner (with its air vent closed) this causes incomplete combustion and as a result carbon black is deposited on the dish. These carbon black particles are often coated with other chemicals making them more hazardous than commercially produced pure carbon black.
Inhaling can be dangerous as it can irritate the lungs, eyes, nose, throat, and cause coughing. Extensive exposure can even lead to cancer so you should avoid breathing it in.
In the tire industry, carbon black is used to strengthen and color rubber. It is also used to color inks and leather, and to insulate electrical equipment.
Carbon black. With an air vent so much closed, the carbon will be extra (the flame will be red and sooty).
Carbon black! Carbon black is a material, today usually produced by the incomplete combustion of petroleum products. Carbon black is a form of amorphous carbon that has an extremely high surface area to volume ratio, and as such it is one of the first nanomaterials to find common use. It is similar to soot but with a much higher surface area to volume ratio. Carbon black is often used as a pigment and reinforcement in rubber and plastic products. The current IARC evaluation is that, “Carbon black is possibly carcinogenic to humans (Group 2B)”. Short-term exposure to high concentrations of the carbon black dust may produce discomfort to the upper respiratory tract, through mechanical irritation.
I know 0 about bunsen burners and what not but if there is no air then how could you support a flame?Okay,if there was air present then I would guess..carbon
What?
