Answer:

The term used to describe a pattern of stars in the night sky is constellations, but to be more accurately, a group of stars that forms a pattern in the sky is called an asterism.

Answer: The correct answer is the option: B. An element with eight valence electrons is chemically unstable.

Explanation:

Hello! Let's solve this!

We will analyze each of the options:

A. The group number of the element provides a clue to the number of valence electrons: it is correct, since it provides the number of valence electrons.

B. An element with eight valence electrons is chemically unstable: this is not correct, since elements with eight electrons in the valence shell cannot react because they already have the last complete shell. Therefore, they are chemically stable.

C. The points must be placed one at a time on each side of the chemical symbol: it is correct, because that is the way to make the point diagram.

D. An atom is chemically stable if all the points are paired: this is correct since this verifies that the point diagram has been done well.

We conclude that the correct answer is the option: B. An element with eight valence electrons is chemically unstable.

Hope this helps.....  Stay safe and have a Merry Christmas!!!!!!!!! :D

Answer:

Number 1 is Conduction. Number 2 is Radiation. Number 3 is Convection. i think if thats how im supposed to word it...

Explanation:

Answer:

1. Each collision passes energy from particles moving quickly to particles moving slowly. In this way, the energy spreads throughout the pan and finally reaches the handle. This process is called conduction. Conduction is the transfer of heat that happens when particles collide with each other.

2. A fire spreads by transferring heat energy in three ways: Radiation, Convection, and Conduction. Radiation refers to the emission of energy in rays or waves. Heat moves through space as energy waves. ... This is the reason that when facing the fire, only the front is warmed.

3. The ways in which energy is dissipated depends on the system: ... for a tumble dryer, the electrical work is transferred into useful internal (thermal) energy which helps to dry clothes and energy is dissipated wastefully by sound waves which cause a rise in the internal energy store (temperature) of the surroundings.

Answer:

Explanation:

The formation of ammonia that occurred by the reaction of nitrogen and ammonia is expressed as:

[tex]3H_{2(g)} + N_{2(g)}[/tex] ⇄ [tex]2NH_{3(g)}[/tex]

where;

The reactants are:

Hydrogen and nitrogen

The product is ammonia.

For the reaction, the equilibrium constant can be expressed as:

[tex]K = \dfrac{[product]}{[reactants]}[/tex]

[tex]K = \dfrac{[NH_3]^2}{[N_2]^3[H_2]^3}[/tex]

From the equilibrium constant conditions, the formation of ammonia and its decomposition due to its reversible reaction back to hydrogen and nitrogen are equal.  It implies that the rate of the forward reaction is also equal to that of the backward reaction.

Thus, during when equilibrium is obtained;

Hydrogen, Nitrogen, and Ammonia are present.

Answer:

The real order is

Rb(37)

Sr (38)

In(49)

Sb (51)

Te(52)

Explanation: Good luck

Elements, from top to bottom, in the correct order of increasing atomic radius starting with the smallest is Rh ( 37 ), St( 38 ), In ( 49 ), S ( 51 ), Te ( 52 ).

A chemical element is a species of atoms, including the pure material made entirely of that species, that have a specific number of protons in their nuclei. Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules.

Any compound that cannot be broken down into simpler chemicals by regular chemical processes is referred to as a chemical element or element. The building blocks of which all matter is made are called elements.

Protons, neutrons, and electrons make up atoms. A compound can be created by combining two different types of atoms. A molecule is a group of atoms that can't be separated from the bigger material it is a part of while still keeping its characteristics.

Thus,  Rh ( 37 ), St ( 38 ), In ( 49 ), S ( 51 ), Te ( 52 ) this is the  correct order of an element  increasing atomic radius starting with the smallest.

Answer:

Options B and C are the two criteria that are most essential

Explanation:

When trying to develop a novel process, it is important that the new process involves the use of equipment that can be operated safely by workers so as to prevent death or injury in the cause of handling this equipment. If this equipment is seen not to be safe or cannot be handled safely by workers, it can/will force workers to previous or alternative methods that require more safe equipment.

Also, the process must be able to maximize the most of the reactants, i.e the process must be able to convert a good percentage of the reactants into the desired product (phosphorus pentachloride) since that is the focus. This will also lead to reduction of byproducts produced which could be useful or otherwise (a loss).

Answer:

Number of electrons.

Explanation:

I hope this helps.

An ion is said to be the molecule or the atom that has the presence of a net electrical charge over them. An ion can have the same protons as the other elemental atom. Thus, option A is correct.

An ion is defined by the atom or the molecule with an electrical charge of positive and negative on them due to the gain or the loss of the electron in their orbits for the bond formations and stability.

The ions of the atom have the same number of protons in their nucleus but the number of the electrons varies as they looses and gain electron to acquire the positive and the negative charge over them.

The presence of the extra or less electron in the orbit or the shell of the atom makes them reactive and allows the electrostatic attraction between them for the bond formation.

Therefore, in option A. the protons are the same in an ion.
