Molecules with oxygen atoms nitrogen atoms or ionizable groups -CO2H and -SO3H tend to be polar. A non-polar molecule is a molecule that does not have regions of positive and negative charge. Ethane is an example of a non-polar substance. A bond is considered nonpolar if the electronegativity difference is less than about 0.4.
When things are different at both ends we call them polar. Also, some molecules have positive and negative ends, and when they are present, we call them polar. Otherwise, it is called non-polar. Polar things can attract or repel each other. Opposite charges attract and charges repel.

Which of the following is TRUE if ΔEsys = -100 J?
The statement that is true if the ΔEsys = -100 J is that the system looses 100J of energy which is gained by the surroundings.
What is the energy of the system?Note that the study of energy is what we call thermodynamics. We should note that according to the laws of thermodynamics, energy can not be created nor destroyed but can be converted from one form to another.
This implies that the energy that is lost by the system must be gained by the surroundings since there can never be energy that goes to waste in the system.

A certain gas is present in a 11.0 L cylinder at 2.0 atm pressure. If the pressure is increased to 4.0 atm , the volume of the gas decreases to 5.5 L . Find the two constants ki , the initial value of k , and kf , the final value of k , to verify whether the gas obeys Boyle’s law.
Express your answers to two significant figures separated by a comma.
A certain gas is present in a container obeys Boyles law.
What is Boyles law?The Boyles law stated that if the temperature and amount of gas remain constant within a closed system, the absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it fills.
Boyles law can be expressed as
P1V1 = P2V2
As per Boyles law P= k / V
So, Pi = ki / Vi
Ki = Pi Vi
= 2.0 x 11.0 = 22.0 atm-L
Thus for Kf
Kf = Pf Vf
= 4.0 x 5.5 = 22.0 atm-L
Thus Ki = Kf
This signify that it obeys Boyles law.

How does the formation of an ionic bond differ from the formation of a covalent bond?
1) An ionic bond is where one atom transfers at least one electron from another atom in an attempt to fill its electron shell. A covalent bond is when electrons are shared
between atoms and there is equality between atoms in relation to their electrons.
2) Ionic bonds form by the transfer of electrons. Covalent bonds form by sharing
electrons. In ionic bonding, electrons are completely transferred from one atom to
another. In the process of either losing or gaining negatively charged electrons, the
reacting atoms form ions. Ions that have a positive charge are called cations and the
ones that have a negative charge are called anions. On the other hand, covalent bonds can be formed by any equal or unequal sharing of electrons. The substances formed by ionic bonds are called compounds and those formed by covalent bonds are referred to as molecules.
3) The formation of an ionic bond differs from the formation of a covalent bond by
being so, a covalent bond forms when one electron in the outer electron orbit of each
atom is shared between the two atoms. Covalent has only one electron to be shared
and ionic has more than one electron to be transferred.

Two standard scuba tanks are filled to 200 atm—the first with a volume of 14.2 L and the second with 11.4 L. Assume that the tank regulator delivers 1.5 L of air at 1 atm for each breath. How many breaths could each different tank supply if one used the contents of each tank completely?
Hint: P1V1 = P2V2*Breaths

First tank with 14.2 L volume delivers 1,893.[tex]\overline 3[/tex] breadths of air
The second tank with 11.4 L volume, delivers 1,520 breadths of air
What is an ideal gas?An ideal gas is a gas that is not subject to particle to particle interactions, and consists of many particles
The given parameters are;
Pressure air in the two scuba tanks, P₁ = 200 atm
Volume of air in the first tank, V₁₁ = 14.2 L
Volume of air in the second scuba tank, V₁₂ = 11.4 L
Volume of air delivered for each breadth, Vₐ = 1.5 L
Pressure of air delivered by the tank regulator, P₂ = 1 atm.
According to Boyle's law, at constant temperature, the pressure of a given mass of gas is inversely proportional to its volume
Mathematically, we have;
P ∝ V
P₁·V₁ = P₂·V₂
The volume occupied by a given number of breadths, n, Vₙ = Vₐ × n
According to Boyle's law, the number of breadths supplied by the first tank is therefore;
P₁·V₁₁ = P₂·Vₐ·n
Which gives;
[tex]n = \dfrac{P_1\cdot V_{11}}{P_2 \cdot V_a}[/tex]
Therefore;
[tex]n = \dfrac{200\times 14.2}{1 \times 1.5}\approx 1893.\overline 3[/tex]
The number of breadths supplied by the first tank is 1,893.[tex]\overline 3[/tex] breadths
Similarly, the number of breadths supplied by the second tank is given by the formula;

Answer:
6. Al
7. 3
Explanation:
When looking at ionization energies to find the number of valence electrons, look for big jumps in ionization energy. The jump from first to second is big, but it's only about 1200 kj/mole (which is considered to be a medium small jump). This means that the first electron and second electrons are both likely valence electrons (since the energy needed to remove them is relatively small). From second to third, the change in ionization energy is less than 1000 kj/mole. Since the third ionization energy is also quite small, the third electron is also likely to be a valence electron. However, looking at the change in ionization energy from the third to the fourth, the jump/difference in ionization energy is nearly 9000 kj/mole! That's 7 to 9 times the amount of the previous jumps. From this, we can reasonably assume that this is a core electron, which takes lots of energy to remove from an atom. Therefore, the fourth electron is a core electron, and this atom only has 3 valence electrons. Now, we can answer question 7. It is C. From this, look at number 6. Na only has 1 valence electron, Mg only has 2 valence electrons, Si has 4 valence electrons, and only Al has 3 valence electrons. Since this mystery element X has 3 valence electrons and Al also has 3 electrons, Al is the most fit for the data given. So the answer to number 6 is C) Al
tl;dr there is a jump of ionization energy from the 3rd ionization energy to the 4th ionization energy so that means that the 4th electron is a core electron, and the element only has 3 valence electrons. Al has 3 valence electrons
