Increasing electronegativity for the following chemical would be: Florine > Carbon > Boron > Aluminum > Calsium > Cesium > Barium.
When atoms can attract electrons during chemical bonding, they are said to be electronegativity.
Electronegativity rises from left to right across the periodic table. The reason for this is that as the atomic number rises, there are more protons. Due to the growing size of the atoms, electronegativity decreases from top to bottom. As a result, fluorine is regarded as the element with the highest electronegative potential, whereas cesium has the lowest. The electronegativity of a halogen is thought to be high, while that of an alkali metal or an alkaline earth metal is thought to be low.

The statements that correctly describe the arrangement of individual particles in the three physical states of matter is
Gases occupy the entire volume of the container.The particles in a solid occupy fixed positions.Liquids take the shape of the container.The particles in a gas move quite freelyWhat are the 3 physical states?
Matter exists in three different states: solid, liquid, and gas. By examining the configuration of their particles, it is possible to understand why they have various qualities. Theoretically, at this temperature, particles move slowly and have the least amount of energy.
Even though the volume filled by gas molecules is small compared to the volume of the container, gases do occupy space. Because of this, the capacity of the container is completely open to the flow of gas molecules.The fact that the particles can only move a little amount causes a solid to have a fixed shape and volume. Although they oscillate back and forth, the particles hold onto their fixed places.Since the particles in a liquid are still in close proximity to one another, liquids have a definite volume. A liquid, on the other hand, lacks a fixed shape and takes the shape of its container since its constituent particles are free to flow around one another.In a gas, particles vibrate and move around freely.To learn more about physical states of matter from the given link.

When a robust acid reacts with a robust base the consequent salt is neither acidic nor primary in nature i.e. it is neutral. for instance while HCl (Hydrochloric acid), a strong acid, reacts with NaOH, a robust base, the resulting salt is sodium chloride and water.
To neutralize acids, a vulnerable base is used. Bases have a bitter or astringent taste and a pH more than 7. Bases are neutralized with the aid of the use of a susceptible acid.

What is an unsaturated solution?; What is a saturated solution?; What happens when you add more solute to an unsaturated solution?; What happens if a solute is added to a saturated solution?
An unsaturated solution is one in which more solute can be dissolved into the solution. The solution has yet not reached its saturation point and its concentration can be further increased.
A saturated solution is one in which no more solute can be dissolved. The solution has reached the maximum concentration that it possibly can at that temperature.
When more solute is added to an unsaturated solution, it dissolves into the solution, increasing the concentration of the solute. Unless the saturation point is reached in the solution, no solute settles at the bottom of the container. Any amount of solute can be added to a solution until it reaches its saturation point.
When more and more solute is added to a saturated solution, it has no effect on the concentration of the solution. The solute settles to the bottom of the container as it can not be dissolved anymore. Causing an increase in the temperature can increase the solubility of the solution and increase the amount of solute that can be dissolved into the solution.
A solution is a homogenous mixture of two or more substances in which one or more substances are dissolved in a medium such as liquid or a gas. The dissolved part that is usually less in mass is called the solute and the dissolving medium that is usually present in excess is called the solvent.

= 22.17 * 17² * 20.4
= 4.630 cm²
As we know that: PV = nRT
moles = weight/molecular weight
moles of boron trifluoride = 98.5/67.82
moles of boron trifluoride = 1.452 mol
PV = nRT
T = PV/nR
T = (22.21 * 4.630)/( 0.0826 * 1.452)
= 863 K
= 863 - 273°C
= 590°C
Temperature of the system is: 590°C

Note: The question given on the portal is incomplete. Here is the complete question.
Question: A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 17.0cm wide and 20.4cm high. The maximum safe pressure inside the vessel has been measured to be 2.20MPa. For a certain reaction the vessel may contain up to 0.0985kg of boron trifluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Round your answer to significant digits.
Can oxygen and sulfur form an ionic bond?
The oxygen–sulfur system would therefore have the strongest ionic character. A difference in electronegativity of 1.0 would result from this.
Can oxygen and sulfur combine?Sulfur dioxide is created when sulfur and oxygen react. A molecular compound is the end result of nonmetal reactions. The nonmetal reactants frequently mix in various ratios to yield various products. Sulfur trioxide is created when oxygen and sulfur interact.
Do oxygen and sulfur have a polar bond?sulfur and oxygen atoms have different levels of electronegativity, SO2 is polar in nature. The polarity of the molecule will increase with the difference in electronegativity.

Sodium Chloride
Sodium and chlorine form a ionic bond because they are sharing their valence
electrons.
Sodium and chlorine form an ionic bond because chlorine transfers its seven
valence electrons to sodium.
In an ionic bond, the atoms are bound together by the electrostatic forces in the attraction between ions of opposite charge.
How sodium chloride is formed?
A metal ion and a nonmetal ion are frequently joined via ionic bonds. For instance, the nonmetal chloride (Cl) and the metal sodium (Na), when combined, form NaCl through the formation of an ionic bond. Both ions, sodium cation (Na+) and chloride anion (Cl-), are formed when a sodium atom donates an electron to a chlorine atom. These two ions have entire valence shells and are therefore more stable energetically. Exothermic in nature, the reaction generates a lot of heat energy as well as a bright yellow light. Ionic bonds are created by the attraction between positive and negative ions. The ionic bond in a sodium chloride (NaCl) molecule is formed by the ions sodium (Na) and chlorine (Cl), which are known as Na + and Cl-.To learn more about sodium chloride refer to:
