An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire create a magnetic field which is concentrated in the hole, denoting the center of the coil

esulfur burns easily .Iron is attracted by magnets .the mineral made by sulfur and iron ,but it does not burn and it is not attr

vladimir2022 [97]

The mineral is Iron Sulphide. It is not a mixture, but a compound. A mixture is when two substances are together, but not chemically bonded. For example, if I add food colouring to water, I have made a mixture because the food colouring has not chemically bonded to the water. If I react Iron with Suphur, the resulting substance is a compound. The resulting mineral will not burn or be magnetic because the compound has different properties to the elements themselves. For example, chlorine gas is toxic and sodium reacts violently with water, but sodium chloride is table salt, nor toxic nor explosive. Hope this helps

By what mechanism does cyclohexanol react when treated in concentrated sulfuric acid/phosphoric acid and what compound results?

slava [35]

Answer:

The mechanism is E1 and the product is cyclohexene

Explanation:

Attached to this answer is an image of the reaction mechanism of the reaction between cyclohexanol and concentrated sulfuric acid/phosphoric acid. The acid (H3O^+) acts as catalyst.

We can see that the first step in the mechanism is the protonation of the -OH group of the alcohol. This is followed by loss of water molecule which is a good leaving group.

The water now acts as a Lewis base by abstracting a proton from the substrate, forming cyclohexene and regenerating the acid catalyst.
