Why is SF6 a nonpolar molecule?

Answers

Answer 1

[tex]SF_{6}[/tex] is non polar due to symmetrical placement of all the fluorine around the central sulfur atom.

SF6 is a covalent molecule with a central sulfur atom. Sulfur on its own contains 6 valence electrons as a main group 6A element. This will share all 6 valence electrons through 6 single covalent bonds to the 6 peripheral fluorine atoms. So the central sulfur atom has zero non-bonding pairs. These bonds are sometime polar due to the central and peripheral atoms having different electronegativity values. The polar molecule contains a certain geometry that does not cancel out these polar bond vectors. Due to its geometry sulfur hexafluoride is non polar. The arrangement of this is at perpendicular (90˚) angles ensures that the pull for electrons by fluorines on one side is balanced by fluorines pulling on the other side.

An atomic orbital can hold a minimum of 6 electrons, each with opposite spins
An atomic orbital can hold a maximum of 6 electrons, each with the same spin
An atomic orbital can hold a minimum of 2 electrons, each with opposite spins

Answers

Pauli Exclusion Principle, states that an atomic orbital can only hold maximum of 2 electrons, each with opposite spins. So, the correct choice is option (a).

The Pauli Exclusion Principle is a quantum mechanical principle that states that no two electrons in the same atom can have the same value for all four quantum numbers. That is no more than two electrons in can occupy the same orbital, and two electrons in the same orbital in must have opposite spins.

Austrian, Wolfgang Pauli proposed this idea in 1925. After reading a paper on quantum states in 1924, Pauli decided to add a fourth value to the classical three values used to describe the state of electrons. Two other scientists, Samuel Goudsmit and George Uhlenbeck, defined the fourth quantum quantity as the electron's spin. So option (a) is the correct option.

In acid-base titration,colour change indicates that neutral point where amount of acid and base becomes equal is going to achieve.

An acid- base titration is a technique for quantitative examination for deciding the grouping of a corrosive or base by precisely killing it with a standard arrangement of base or corrosive having known focus. A pH marker is utilized to screen the advancement of the corrosive base response. In the event that the acid separation consistent (pK[tex]_a[/tex]) of the corrosive or base separation steady (pK[tex]_b[/tex]) of base in the analyte arrangement is known, its molar concentration (molarity) still up in the air. On the other hand, the pK[tex]_a[/tex] still up in the air if the analyte arrangement has a known arrangement focus by building a titration bend.

A reasonable pH indicator should be picked to recognize the end point of the titration.

Polarity has an impact on the strength of intermolecular forces as well. Non-polar molecules only exhibit the van der Waals force as an intermolecular force.

What is the difference between polarity and intermolecular forces?

The strength of intermolecular forces is also influenced by polarity. The van der Waals force is the only intermolecular force that non-polar molecules display. Dipole-dipole interactions, which are often stronger than van der Waals forces, can be used to connect polar molecules together.

As the polarity is raised, the forces between dipoles get stronger. In this situation, dipole-dipole forces are highly powerful. It is possible for it to exist between a molecule with an N, O, or F atom that has a hydrogen atom directly connected to it and another molecule with an N, O, or F atom that has a lone pair of electrons on it.

An electrolyte is a substance that conducts electricity when dissolved in water or another solvent. It is composed of ions, which are electrically charged atoms or molecules. Common electrolytes include sodium, potassium, chloride, calcium, and magnesium. Electrolytes are important for maintaining the balance of the body's fluids, as they help regulate the body's acid-base balance, hydration, and muscle and nerve function.

HF is a weak electrolyte because it only partially dissociates in water, forming H+ and F- ions. This is in contrast to strong electrolytes, which fully dissociate in water, forming many ions. HF is the chemical formula for hydrofluoric acid, which is a colorless and highly corrosive solution of hydrogen fluoride in water.

Determine the moles of aluminium ions in 1. 25mol of AI203

The moles of aluminum ions in 1.25 mol of Al2O3 are 2.49 moles .

Aluminum oxide (Al2O3) dissociates in water to form aluminum ions (Al3+) and oxide ions (O2-). The molar mass of Al2O3 is 101.96 g/mol.

To determine the moles of aluminum ions in 1.25 mol of Al2O3, we need to first calculate the number of moles of Al2O3 present in 1.25 mol. We can do this by dividing the given mass of Al2O3 by its molar mass:

mass of Al2O3 = number of moles x molar mass

number of moles = mass of Al2O3 / molar mass

number of moles = (1.25 mol) x (101.96 g/mol) = 127.45 g

Next, we need to use the stoichiometry of the dissociation reaction to determine the number of moles of aluminum ions produced from 127.45 g of Al2O3:

1 mol of Al2O3 produces 2 mol of Al3+ ions

mol of Al3+ ions = (127.45 g Al2O3) x (1 mol Al2O3/ 101.96 g Al2O3) x (2 mol Al3+/ 1 mol Al2O3) = 2.49 mol

(5 points)coordinate plane showing the point 1, 8, point 2, 4, point 4, 1, and point 5, .5an = 8(one half)n 1; average rate of change is 3an = 10(one half)n 1; average rate of change is 3an = 8(one half)n 1; average rate of change is 3an = 10(one half)n 1; average rate of change is 3 Two steel balls that are the same mass and size are rolled with the same force across different level surfaces. The ball rolling across carpet will come to a stop faster than the one rolling across concrete because of. From Fiber to FashionWho knew fashion design included so much science?Imagine for a second that you are a scientist. Predict the source of the clothing you have on right now without looking at the labels. Think about the appearance and feel of the fabric. Do you think the outfit you are wearing now is made of synthetic (produced from chemicals) or natural fibers? Why do you think that? Do you think one fiber type is better than the other? Explain why. why is it necessary that a force probe be calibrated?
