What is the yellow powder that gives a pungent smell when left open in air?
sulphur powder
What happen when sulphur is heated in the absence of air?
Sulfur is melted.
What is the chemical name for the white powder formed when magnesium burned in air?
Magnesium oxide anything that is burned with oxygen (what is left) is called [material you burned] oxide
What happen ton sulphar when slightly heated in test tube by a Bunsen burner?
When sulphur is heated in the test tube in the absence of air the sulphur will break down and form a red-brown liquid. If oxygen comes into play sulphur dioxide is produced, however you should not that sulphur dioxide is a highly toxic gas and should only be produced in small amounts under a fume hood.
How do you get sulfur?
Sulphur is an important non-metallic yellow element. At ordinary temperature it exists as a solid. It melts at 119deg.c and boils at 444deg.c. It does not dissolve in water but does so in carbon disulphide. Its atomic number is 16 and relative density is 2.Sulphur is found in different forms. These are called allotropes of sulphur. Its three important allotropic forms are: rhombic sulphur, monoclinic sulphur, and plastic sulphur. The common form is called rhombic sulphur. It is made up of eightsided yellow crystals.When it is heated to more than 950deg.c, it changes into monoclinic sulphur. when the molten sulphur. When the molten sulphur is pored into cold water, it changes into plastic sulphur. Another allotrope is called flowers of sulphur. It is a yellow powder and is made by quickly cooling sulphur vapour.Large deposits of sulphur are found beneath the earth in several layers, especially in the United States. It is mined by a method called the Frasch process. This method was developed by Herman Frasch in 1891. employing this method ,three coaxial pipes of different diameters are inserted into the earth upto the sulphur bed. superheated water,at 170deg.c, is pumped down the outer pipe and compressed air is pumped down the central pipe . The sulphur is melted by the hot water and forced up by compressed air. The melted sulphur comes up through the middle pipe. It is collected in big wooden vats. Sulphur obtained by this process is 99.5% pure. Sulphur also occurs in nature as hydrogen sulphide gas, calcium sulphate and as sulphides.Sulphur is a reactive element.It burns in the air with a blue flame to form sulphur dioxide. This gas pollutes the air. Sulphur trioxide is another oxide of sulphur which dissolves in water and forms sulphuric acid.Most sulphur is used to make sulphuric acid. It is of great industrial importance. Sulphur is used in making wood pulp and for vulcanizing rubber. It is also used to make wide range of products like drugs, dyes and chemicals to kill insects and moulds. It is also used in manufacture of gun-powder and matches.
What experiment did Antoine lavoisier do?
He burned sulphur in air to get Sulphur oxide
What is the yellow powder that gives a pungent smell when left open in air?
sulphur powder
What happen when sulphur is heated in the absence of air?
Sulfur is melted.
What fuels are in the air when hydrocarbons are burned?
sulphur oxicide, carbon dioxide, carbon monoxide and carbon.
How does burning carbon dioxide and sulphur dioxide pollute the air?
The chemicals that are burned make the air we breathe bad. Plus it is burned and turns into smoke and smoke is not good for the human lungs.
What will happen when coal is burned in the absence of air?
It will not burn.
What is the chemical name for the white powder formed when magnesium burned in air?
Magnesium oxide anything that is burned with oxygen (what is left) is called [material you burned] oxide
What can you learn from heating sulphur?
By heating sulfur is melted at 115,21 0C and boiled at 444,6 0C. Sulfur is burned at high temperature in an air atmosphere.
What happen when bleaching powder is left exposed to air?
it gradually looses its color.
What is sulphur precipitator?
it is a device that extracts sulphur from the air they can be found in chimneys
How are humans altering the amounts of sulphur dioxide in air?
Humans are altering sulphur in air by releasing it. It is released as pollution.
What will you produce if you burn sulphur in the air?
You will get SO2 or sulphur dioxide, an acidic oxide
