Decide which element probably forms a compound with chlorine that has a chemical formula most and least similar to the chemical

formula of the compound formed by chlorine and barium

The compound formed by chlorine and barium is BaCl_2 as the number of valence electrons in barium is 2 and in chlorine is 1. In this compound, barium acts as a cation and chlorine acts as an anion. The formation of the compound is as shown in the image.

Since, barium is an element of Group-2 (alkaline earth metal) so the other element that has a chemical formula most and least similar to the chemical formula of the compound formed by chlorine and barium should be from Group-2 (alkaline earth metal) only which has properties somewhat like barium. So, the element is strontium.

Strontium forms a compound with formula SrCl_2 in which strontium acts as a cation and chlorine acts as an anion. The formation of the compound is as shown in the image.

Rank the effective nuclear charge Z* experienced by a valence electron in each of these atoms:
LekaFEV [45]

Answer:

The atoms are ranked in decreasing order as follows:

Fluorine ---4

Carbon ----3

Boron ------2

Beryllium --1

Explanation:

Effective nuclear charge (Zeff) is defined as the difference between the actual nuclear charge (the atomic number, Z) and the shielding constant (S).

It is calculated by finding the atomic number and electronic configuration, attributing a shielding value to each electron, adding all the shielding values and using the formula:

                 Z eff = Z - S

Effective nuclear charges:

An atom of carbon: 3.25

An atom of fluorine: 5.20

An atom of beryllium: 1.95

An atom of boron: 2.60

A scientist places a strip of hot metal on top of a block of another metal with a lower
tia_tia [17]

The heat transfer that we'll have will be:

- At first, the metal bar will emanate heat through radiation, to the atmosphere, and to the second metal, through conduction.

- Because of this, the second bar will start to increase it's temperature, up to the fusion point, spending the energy received on the fusion, and also radiating heat to the atmosphere. It won't emit heat in any other form, since heat transmission can happen only from a hot body to a cooler one, and the only things in contact are the two bars.

A chemistry student conducted several different procedures. Which of the following procedures best demonstrates the law of conse
Vsevolod [243]

Answer:

combining 2 grams of copper and 4 grams of sulfur to make 6 grams of copper sulfate

Explanation:

The Law of Conservation of Mass states that matter cannot be created or destroyed in chemical reactions. It posits that the mass of a substance remains unchanged after undergoing a chemical process.

Therefore, according to the question, the procedure that best demonstrates the law of conservation of mass after the chemistry student conducted different procedures is option D.

This is because, the mass of copper and sulfate did not change but merely combined to form a compound.

show transcribed data consider two organic molecules, ethanol and benzene. one dissolves in water and the other does not. why? t
aalyn [17]

Benzene lacks a polar O-H bond, but ethanol does. Benzene C6H6 with ethanol C2H6O.

Benzene fails the iodoform test, whereas ethanol does.

While ethanol burns with a non-luminous flame, benzene produces a sooty flame.

Iodoform testing shows that ethanol passes whereas benzene does not.

In contrast to benzene, which generates a sooty flame, ethanol burns with a non-luminous flame.

Water does not mix with benzene, but organic solvents do.

It is a colorless liquid with a pleasant scent.

Benzene has a high melting point and a moderate boiling point.

It burns with a sooty flame and is quite flammable.

A clear, colorless liquid, ethanol has a distinct flavor of burning with a nice aroma. It has high flammability. Ethanol combines easily with water and a variety of organic liquids and is used to dissolve other chemical compounds.
