How do you make iron sulfide?
The equation for the reaction that produces the iron sulfide is: Fe + S → FeS (heat) Page 2 Maine Geological Survey | 2 One atom of iron (or a million atoms of iron) and one atom of sulfur (or one million atoms of sulfur) react with heat to make one molecule of iron sulfide (or a million molecules of iron sulfide).
What is iron and sulfur?
Iron and sulfur react together when they are heated to make a compound called iron sulfide. the mixture can contain more or less iron, but iron sulfide always contains equal amounts of iron and sulfur. the iron and sulfur atoms are not joined together in the mixture, but they are joined together in iron sulfide.
Is iron sulfide A mixture or pure substance?
Iron sulphide is not iron or sulfur; it is a pure substance with its own set of distinguishing physical and chemical characteristics. A mixture, on the other hand, is what you get by combining two or more elements, but not chemically combining them.
What is the colour of mixture of iron and sulphur?
The correct option is (c). Iron filings and sulphur after heating form iron sulphide, FeS which is black in colour.
What is the mixture of iron?
Natural iron is a mixture of four stable isotopes: iron-56 (91.66 percent), iron-54 (5.82 percent), iron-57 (2.19 percent), and iron-58 (0.33 percent).
What are the materials used to make glass?
SAND AND LIMESTONE FOR GLASS MAKING. 453. DEFINITION AND COMPONENTS OF GLASS. Glass is a fused mixture of the silicates of alkalies, alkaline earths, and of more common metals. Usually the alkaline bases are sodium and potassium; the alkaline earth is calcium, and the common metallic element is lead.
What is glassware made out of?
Glass is a fused mixture of the silicates of alkalies, alkaline earths, and of more common metals. Usually the alkaline bases are sodium and potassium; the alkaline earth is calcium, and the common metallic element is lead. All of these are used’in the form of salts.

How do you fix a broken wire on glasses?
Use temporary adhesive putty (Scotch’s 860) to position the glasses for soldering. Flux the wrap so that solder flows well. Solder lightly to strengthen the bond, but do not use too much solder to allow for an additional layer. Use just enough solder so that it ends up between the copper wire and the broken frame.
