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.

Answer:
3. Homogenous and unsaturated
Explanation:
Since your given information mentions 50 grams of solvent and 5 grams of solute, you must double each amount because "
Table G Solubility Curves" in the Regents Chemistry Reference Table notates curves based off of 100 g samples of water. Therefore, you must look for how soluble 10 grams of KCl is in 100 grams of water at 25 degrees Celsius.
As the picture shows, 10 grams of KCl is well below the curve for saturation, meaning that the solution is undersaturated.
As for the second part of the answer, we can tell that the solution is homogenous (of uniform composition) because there is no possibility of the salt, KCl, falling out of solution and making the mixture heterogenous (of mixed composition).
Putting all of those ideas together, we can tell that the answer to this question is:
3. Homogenous and unsaturated
