The most common charge associated with scandium in its compounds is $3+.$ Indicate the chemical formulas you would expect for compounds formed between scandium and (a) iodine, ( b) sulfur, (c) nitrogen.

Answers

Answer 1

Iodine and scandium have charges of -1 and +3 respectively in their compounds, while sulfur and nitrogen have charges of -2 and -3. Hence ScI3, Sc2S3, and ScN would make up the compound's formula.

The lanthanide iodide scandium triiodide, also known as scandium iodide, is an inorganic chemical having the formula ScI3. As a semiconducting component in epitaxial metal/semiconductor superlattices, the rocksalt-structure semiconductor scandium nitride (ScN) has drawn interest for its possible use in thermoelectric energy conversion devices. With the chemical formula Sc2S3, scandium(III) sulphide is a combination of scandium and sulfur. It's a solid yellow color. Sc3+ and S2 ions from scandium make to the compound Sc2S3. An ionic compound is a thing formed of ions in an ionic connection.

Why is furan an aromatic compound?

Answers

Furan is an aromatic compound because it has a cyclic conjugated structure that allows the molecule to delocalize its electrons.

This delocalization gives the molecule a stable structure and makes it highly resistant to chemical reactions.

An aromatic compound is a type of organic compound that contains a ring of atoms with alternating single and double bonds. This ring is made up of carbon and hydrogen atoms and is held together by a special type of strong bond called a pi bond. Aromatic compounds are usually aromatic in nature, meaning they have a pleasant smell. Examples of aromatic compounds include benzene, toluene, and xylene.
