Explanation:
oxide or ferric oxide is the inorganic compound with the formula Fe₂O₃. It is one of the three main oxides of iron, the other two being iron(II) oxide, which is rare; and iron(II,III) oxide, which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe₂O₃ is the main source of iron for the steel industry. Fe₂O₃ is readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition; however, in chemistry, rust is considered an ill-defined material, described as Hydrous ferric oxide.
Answer:
In the mixture of table salt, sand, solid iodine and iron fillings, iron filings is the only solid that is magnetic. Hence, it can be separated using a magnet. When a magnet is moved through the mixture, iron fillings get attracted to the magnet out of the mixture, leaving the salt, iodine and sand.

Answer:
Here's what I get
Explanation:
CH₃CH₂CH₂CH₂CH₂CH₃ — hexane
CH₂=CHCH₂CH₂CH₂CH₃ — hex-1-ene is the preferred IUPAC name (PIN). 1-Hexene is accepted
CH₃C≡CCH₃ — but-2-yne (PIN); 2-butyne is accepted
CH₃CH(CH₃)CH₂CH₂CH₃ — 2-methylpentane
CH₃CH₂CHCICH₂CH₃ — 3-chloropentane
I think it’s C, since we know for sure the Sun is not the only one in the Universe because there are other starts among the Milky Way do that can eliminate all the other options
