Answer:
C) quartz
Explanation:
Quartz is a common mineral. Also, quartz isn't a metallic substance. I'm hoping that this helps :)
The answer is- Gasoline - homogeneous, Soil- heterogeneous, Cranberry juice - homogeneous and Salt water-homogeneous.
Mixture: The substance that has two or more elements or compounds mixed together without binding them chemically is known as mixture.
The constituents of mixture can be separated by various methods.
What are homogeneous and heterogeneous mixture?
- Homogeneous mixtures- Homogeneous mixtures are those that have same composition throughout its mass and there are no visible boundaries between its components.
- Heterogeneous mixtures- When solute particles are not mixed uniformly in the solvent particles, then a heterogenous mixture is obtained.
- Gasoline: It is a homogeneous mixture of various hydrocarbons.
- Soil: Soil is a heterogenous mixture and its various components can be seen clearly.
- Cranberry juice: It is also a homogeneous mixture as cranberry and water are mixed uniformly.
- Salt water is also a homogeneous mixture as salt and water are mixed uniformly.

Answer:
monochlorinated products: 4
dichlorinated products: 12
Explanation:
Chlorination of alkanes is a reaction that takes place when the chlorine is in presence of light. This actually decomposes the chlorine, and one atom of Chlorine substracts an hydrogen from the alkane. Now, this hydrogen substracted comes usually from the most substitued carbon, because it's more stable (A tertiary carbon is more stable than a secondary carbon, and this more stable than primary).
When this happens, the other chlorine atom, goes as electrophyle in that carbon and formed the chlorinated product. Now, although a tertiary carbon is more stable, we can still have (in minor quantities) chlorinated products that comes from a secondary and primary carbon. The first picture shows the general mechanism of the chlorination, and the possible products for a monochlorinated.
The second picture shows the possible dichlorinated products, which are in higher quantities than the monochlorinated basicallu because of the variety of positions the chlorine can be. So, second picture shows all the products.
Answer:
Progress made in Asia and the Middle East is clear, with nations such as China, Singapore and Malaysia all demonstrating increased adaptability. Much of Africa has also made progress since 1995, along with South American nations, including Brazil and Chile.
