How do you make selenium sulfide?

Answer 1

Selenium is an element it was "made" in the nova of an exploding star several billion years ago.
Selenium is found on Earth in minerals such as pyrites where it partially replaces the sulfides. Native selenium is very rare. Most elemental selenium on the market comes as a byproduct of metal refining such as copper or the production of sulfuric acid.

Answer 2

Selenium sulfide can be made by reacting elemental selenium with sulfur, typically in the presence of a reducing agent. The reaction usually takes place at high temperatures. Alternatively, selenium sulfide can be prepared by reacting selenium dioxide with hydrogen sulfide gas under controlled conditions.

Answer 3

Selenium is a naturally occurring element. It is rarely found in nature as a pure element. It can be found in metal ores such as:

Berzelianite (Copper Selenide)

Clausthalite (Lead Selenide)

Eucairite (Silver Copper Selenide)

Hakite (Copper Mercury Silver Antimony Selenium Sulfide)

Klockmannite (Copper Selenide)

Palladseite (Palladium Selenide)

Penroseite (Nickel Selenide)

Selen-tellurium (Selenium Tellurium)

Tiemannite (Mercury Selenide)

Umangite (Copper Selenide

Pure selenium is usually produced as a by-product of refining copper sulfide for copper, where it is an impurity.

Answer 4

Some application of selenium are:

- vulcanization agent

- pigment for glass

- photocells

- additive in the process of manganese extraction by electrolysis

- component of alloys

Answer 5

it is used mainly for gases and heating oils, thus having the correct number of neutrons protons and electrons

Answer 6

i know a photophone device that was invented by alexander graham bell and it uses selenium to send signal at a distance

Answer 7

Selenium is found in nature as selenide ores

Answer 8

found in nature
