Which of the following would be the best name for MgCl2? magnesium chlorine magnesium chloride magnesium dichloride monomagnesium dichloride

Answers

Answer 1

Answer:

Answer: magnesium chloride

Explanation: Magnesium chloride is an ionic compound which is formed by combination of $Mg^(2+)$ and $Cl^-$ ions.

The name of the ionic compound is written as follows:

The name of the metal is written first followed by the name of the non metal without any prefix but the name of the non metal ends with ide, ite, ate or ite.

Thus the name of $MgCl_2$ is magnesium chloride.

Answer 2

Answer: It would be magnesium chloride.

Chlorine is a wrong name for Cl.

Dichloride doesn't work, even though Cl2 is 2 chloride, but according to some laws of nomenclature, saying dichloride isn't necessary so we don't say it.

And monomagnesium isn't right for the same reason as above.

What’s the easiest way to add energy to matter

Answers

Answer:

The easiest way is to heat matter which raises its internal energy andso the mass as well. Another possibility is to accelerate matter as in case of protons or heavy ions in the LHC, Protons ,for example , are accelerated to the energies of 6500 GeV which means increase of the rest mass by a factor of almost 7000

Most metals are not?

Answers

Most metals are not liquid at room temperature. They are typically solid and have a crystalline structure. Therefore, the correct option is option 3.

Metals are known for their high thermal and electrical conductivity, as well as their malleability and ductility. These properties allow metals to be shaped into various forms, such as wires and sheets, and conduct heat and electricity efficiently.

However, the majority of metals have a solid state at room temperature, with exceptions such as mercury, which is a liquid metal. The solid nature of metals is due to the metallic bonding between atoms, which involves the sharing of electrons within a sea of delocalized electrons.

Thus, the ideal selection is option 3.

Which of the following is a physical property of a substance?? A. Combustion B. Corrosion C. Tendency to tarnish D. Solubility

Answers

A physical property does not change the substance.

Solubility would be the answer since all of the rest are changing the substance. They all deal with bonds except solubility.

Answer: D. Solubility

A physical property is any property that doesnot concern with the change of the substance. The changes in the physicalproperty can be used to describe its transformations or evolutions from itsinitial state. They are often referred to as observables. Solubility is an example of a physical property.The solubility of substance describesa state of a dissolving a powdered form in a liquid. Combustion, Corrosion andtendency to tarnish are examples of a chemical change. They are substances thatchanges its physical state and composition resulting from a chemical reaction
