Use the IUPAC nomenclature rules to give the name for this compound - SiO2. A) silicon oxide B) silicon dioxide C) silicon (IV)
2 answers:
Answer: Option (B) is the correct answer.
Explanation:
According to the IUPAC nomenclature when a metal combines with a non-metal then name of cation remains the same. Whereas suffixe "-ide" is added at the end of the name of anion.
For example, in case of the cation is silicon and anion is oxygen. As two atoms of oxygen are involved in this compound so, the prefix "-di" is added before the name of anion.
Hence, we can conclude that the name of is silicon dioxide.

Inequalities are used to represent unequal expressions.
The solution set to is:
The inequality is given as:
From the inequality above, we have the following observation.
- The value of variable x starts from 7/16 (inclusive)
- The value of variable x has no end (i.e. infinity)
Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [
We treat , as an exclusive value. So, we make use of the close parenthesis i.e. )
Hence, the solution set is:
