Aqueous magnesium chloride is not used to extract magnesium. Explain why.

Chemistry
1 answer:
Firlakuza [10]2 years ago
4 0

Explanation: Magnesium chloride, MgCl2, dissolved in seawater, is an abundant, natural source of the very useful metal magnesium. Magnesium is a common component of alloys. Alloys are produced by combining a pure metal with one or more other elements to form a new substance with desirable properties. (Steel, for example, is a common alloy of iron and carbon.) Magnesium alloys are found in aircraft, automobiles, rockets, luggage frames, portable power tools, cameras, laptop computer casings and mobile phones.

Magnesium lends lightness and strength to alloys—a real plus for the owners of fuel-consuming vehicles, or travelers carting luggage. And magnesium alloy construction helps dampen the noise and vibration associated with the use of hand-held power tools, such as electric drills and nail-shooting guns.

which piece of evidence provides the strongest support for the theory that all living things evolved from a common ancestor?    
lianna [129]
There are many pieces of evidence provided as strong evidence: fro example the Comparative anatomy of many species. <span>This evidence is based on compares of the the skeletons of humans, cats, whales, and bats, illustrating how similar they are even though these animals live unique lifestyles in very different environments. Another piece of evidence is </span><span>biochemistry of all living things on Earth. This is so because is incredibly similar. This shows that all of Earth’s organisms share a common ancestry.</span>

Our recorded observations are called.
trapecia [35]

Answer:  Raw data, perhaps.

Explanation:  I'm not certain what the question is seeking for an answer, but I would suggest "raw data" would be a reasonable choice.  It reflects the data was recorded, but not yet processed to provide a conclusion or observation.

If one were a bit snarky, other possiblities include

  • a pile of dung
  • my labmate's scrawls, or
  • the best web results I could find

mart [117]
A substance floats or sinks in another because of its relative density. Take ice floating in water for example. Water is more dense than ice so ice floats.

Mass is incorrect as the buoyancy or ability of an object to float depends on the mass per volume, which is equivalent to density.

Which chemical in the atmosphere of Titan (a moon of Saturn) plays the same role that water plays on the Earth by producing "rai
ololo11 [35]

Answer:

Methane (CH₄)

Explanation:

Titan refers to the largest moon of the planet Saturn, comprising a very dense atmosphere. This moon is primarily comprised of nitrogen gas, which is similar to the conditions in earth. It is extremely cold having a temperature of about ₋180°C, as a result of which it is difficult for the liquid water to exist.

Acid rain is a type of precipitation that occurs in the earth and it results in the release of a certain amount of methane gas (CH₄). Similarly, there also occurs precipitation in Titan but it releases CH₄ instead of water.  This methane is responsible for the increasing amount of temperature.

Thus, methane is a chemical that is present int the Titan's atmosphere, and it plays a similar role as in earth, the water plays by forming snow, rain, and ice.
