When there is a whole transfer of valence electron between the atoms is called an ionic bond. In this type of bond construction, the atoms get contrarily charged.
The ionic bonds are formed due to electronegativity. According to Pauling, the capability of an atom to draw electrons towards itself is called electronegativity.
When there is a huge contrast in electronegativity between the atoms, the electrons are completely transferred between the atoms.
The atom that relinquishes an electron are called a cation and is positive whereas the atom that acquires an electron are called anions and are negatively charged.
Therefore, due to electronegativity, ionic bonds are formed.

Explanation:
Las Vegas Raiders' running back Josh Jacobs is 72 inches tall and has mass of 100 kg. Los
Angeles Rams' defensive tackle Aaron Donald is also 72 inches tall but has a mass of 130
kg. Josh runs the ball East, towards the goal line, quickly traveling 50 yards in
5.5 seconds. Josh then accelerates towards the goal line at 9 m/s2. Aaron accelerates
West, the exact opposite direction, towards Josh at 6.5 m/s2. They both meet with an
explosive collision at the 1 yard line.
In a paragraph, address the following questions. Calculate numerical answers to the
nearest hundredth and correct units must be included.
1. What is Josh Jacobs' speed?
II. What is Josh Jacobs' velocity?
III. How much force does Josh Jacobs create?
IV. How much force does Aaron Donald create?
V. By calculating the net force, does Josh Jacobs score the touchdown.
Explain why or why not?
Answer:
Josh is running at a speed of 9.09 yards per second.
Josh's velocity is 9.09 East.
Josh's force is 900 N.
Aaron Donald's force is 845 N.
Yes Josh scores the touchdown because he is faster and has more mass than Donald.
Explanation:
Josh scores the touchdown as he is heavier and faster than Donald.
Formulas are:
Force= mass x acceleration
Speed= distance divided by time.
Velocity= distance divided by time.
Where v stands for __________________________________ and the units are meters per second (m/s).

The chemical formula for the ionic compound aluminum sulfite is Al2(SO3)3. Explain why there are 2 cations for every 3 anions in this compound.
Answer:
Explanation:
While trying to write the chemical formula for a compound (a neutral molecule), one must identify and exchange the charge of the cation with that of the anion to become the subscript of one other. For example
Aluminium oxide has Aluminium (Al) and oxygen (O); since Al has a charge of 3+ (the cation) and O has a charge of 2- (the anion), the compound would have it's charges as Al³⁺O²⁻ and when the charges are exchanged to there subscripts, it would form Al₂O₃; thus there would be two cations of aluminium for every three anions of oxygen in order to have a neutral molecule.
This same explanation can be given to Aluminium sulfite. Aluminium sulfite has Aluminium (Al) and sulfite (SO₃). Al has a charge of 3+ (cation) while sulfite has a charge of 2- (anion), with the compound having it's charges as Al³⁺(SO₃)²⁻ and when the charges are exchanged to there subscripts, it would form Al₂(SO₃)₃ and would thus have 2 cations of aluminium (Al³⁺) for every 3 anions of sulfite (SO₃³⁻) in order to have a neutral molecule.

A sample of gas is stored at 15 atmosphere and has a volume of 5 liters.If the volume of the gas is reduced to 3 liters,what will the new pressure be?
The new pressure will be : 25 atm

At a constant temperature, the gas volume is inversely proportional to the pressure applied
[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]

Whats the Difference between a chemical and physical change
Answer:
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.

Provide your answer in the following format: [element name], [chemical family]
Answer: Bismuth (Bi) , Nitrogen family
Explanation:
As the element has 5 valence electrons in the sixth energy level, which mens it belongs to 6th period as the valence electron has entered the 6th energy level.
Now as the electrons are filled according to afbau's rule , the electronic configuration of the element will be :
[tex][Xe]4f^{14}5d^{10}6s^26p^3[/tex]
Now as the atomic number of element is equal to the number of electrons in a neutral atom , the atomic number is 83 and the element is Bismuth (Bi). As the last electron enters p -subshell , it is a p block element. It lies in group 15 which is nitrogen family.

Which choices are layers of the atmosphere?
Select the five correct answers.
Thermosphere
Meteorosphere
Croposphere
Stratosphere
Mesosphere
Danosphere
Exosphere
Troposphere
Answer:
Mesosphere
Stratosphere
Thermosphere
Troposphere
Exosphere
Explanation:
The exosphere refers to the farthest region of the atmosphere that gradually fades into space.
The troposphere is the lowest layer of atmosphere. It is the layer where weather changes occur.
The thermosphere is right above the mesosphere but just below the exosphere. It is the layer where photoionization/photodissociation of molecules occurs thereby creating ions. This largely owes to interaction of molecules in this layer with ultraviolet radiation.
The stratosphere is composed of gases. Prominent among them is ozone which serves as a blanket against the sun's ionizing radiation.
The mesosphere lies above the stratosphere but just below the thermosphere. Temperature decreases steadily with height in the mesosphere.

A gas sample has volume 3.00 dm3 at 101
kPa. What will be the volume if the
pressure is reduced to 14.2 kPa?
Answer:
21.3dm³
Explanation:
Given parameters:
Initial volume of gas = 3dm³
Initial pressure = 101kPa
Final pressure = 14.2kPa
Unknown
Final volume = ?
Solution:
To solve this problem, we use the Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁ V₁ = P₂ V₂
P and V are pressure and Volume
1 and 2 are the initial and final states
Now insert the parameters and solve;
101 x 3 = 14.2 x V₂
V₂ = 21.3dm³

The volume of Oxygen at STP required : 251.25 L
Further explanationConditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.
Reaction(combustion) :
2C₂H₂(g)+5O₂(g)⇒4CO₂(g)+2H₂O(g)
mol C₂H₂ :
[tex]\tt \dfrac{100.5}{22.4}=4.49[/tex]
mol ratio C₂H₂ : O₂ = 2 : 5, so mol O₂ :
[tex]\tt \dfrac{5}{2}\times 4.49=11.23[/tex]
volume O₂ at STP :
[tex]\tt 11.23\times 22.4=251.55~L[/tex]
Or you can use Avogadro's hypothesis :
In the same temperature and pressure, in the same volume conditions, the gas contains the same number of molecules
So the ratio of gas volume will be equal to the ratio of gas moles :
[tex]\tt \dfrac{V_1}{V_2}=\dfrac{n_1}{n_2}\\\\\dfrac{100.5}{V_2}=\dfrac{2}{5}\\\\V_2=\dfrac{100.5\times 5}{2}=251.25~L[/tex]
