The ozone in the atmosphere significantly absorbs solar ultraviolet light, notably the dangerous, high-energy UV-a and UV-b rays.
How is UV radiation absorbed by the ozone layer?Ozone is created when atomic oxygen (O) recombines with molecular oxygen (O3). The UVB band's short wavelengths are absorbed by ozone, which prevents organic molecule photochemical reactions. Ozone is broken down into molecular oxygen by reactive chlorine (Cl) generated from CFCs, which does not absorb UVB rays.
What processes are involved in the stratospheric ozone layer destruction?Cl + O3 and ClO + O are the two fundamental reactions that make up the cycle. Overall, Cycle 1 produces two oxygen molecules from one ozone molecule and one oxygen atom.

Why is francium the most reactive metal?
Francium is an alkali metal with atomic number 87 is present in seventh period.
As we go down the group, the number of shells are added and the gap between nucleus and electrons in valence shell increases.
which means the electron in outer most shell, experiences more shielding.
Or we can say that electron in outer most shell experiences less attraction to the nucleus.
This means, the outer most valence electron is easy to remove in case of Francium than any other elements of group 1.
Also, Francium has the lowest electronegativity and with largest atomic radius.
So removal of its valence electron is easy making Francium as the most reactive metal.
And this is the reason why, the most reactive metal on the periodic table is francium.

The molecule Difluoromethane will have higher boiling point. The dispersion forces depends upon molar mass only and Molar mass of Dichloromethane is greater than molar mass of difluoromethane.
Since molecule is highly polar due to strong dipole dipole interaction boiling point is so low. London dispersion forces occur when one molecule has a "temporary dipole" in the beginning and this creates an "induced dipole" in another molecule. Hence London dispersion forces are the attractions between the temporary dipole and the induced dipole while Dipole Dipole forces are only polar molecules because they need dipoles to exist permanently. C-F bond in more polar than C-Cl hence , interaction will be more in Difluoromethane molecule so lower vapor pressure hence higher Boiling point.

The tapetum lucidum, a reflective substance found in the choroid coat of cows, is responsible for a cow's ability to see at night by reflecting light that is absorbed by the retina back into the retina.
Many vertebrates and certain other creatures have a tissue layer in their eyes called the tapetum lucidum. There is a retroreflector directly behind the retina. It increases the amount of visible light that is available to the photoreceptors by reflecting it back through the retina (although slightly blurring the image). Some animals have excellent night vision thanks to the tapetum lucidum. The majority of these creatures are nocturnal, particularly the carnivores, while others are deep-sea creatures.
Some spider species have comparable adaptations. Humans are haplorhine primates, which do not have a tapetum lucidum and are nocturnal.

The most polar connection is F-H.
What type of bond has the highest electronegativity?
The most electronegative element is fluorine. Therefore, carbon and fluorine exhibit the largest variation in electronegativity (C - F). The most polar bond is the C-F one as a result.
How do you tell which connection is the most polar?
The bond is more polar the more electronegativity there is between the two atoms. The difference in electronegativity must be greater than 0.4 on the Pauling scale to be regarded as a polar bond.
Is OO ionic, nonpolar, or polar?
Answer and justification Since the two oxygen atoms share an electron, an O-O connection is covalent. Since the atoms connected together are identical oxygen atoms, the connection is also nonpolar.
Is HF more polar or O-H?
Fluorine is more electronegative than oxygen. Thus, compared to Fluorine in HF, oxygen in H2O draws electrons from hydrogen less strongly. H2O is therefore less polar than HF.

The octet rule and formal charges must be met in order to achieve the "optimal" electron configuration. Lewis structures use the chemical symbol for each atom to show where it is located within the molecule's structure. Atoms that are joined together are separated by lines (pairs of dots can be used instead of lines). The extra electrons that form lone pairs are shown next to the atoms as pairs of dots. Hydrogen (H) can only form bonds that share two electrons, whereas main group elements of the second period and beyond often react by acquiring, losing, or sharing electrons until they have reached a valence shell electron configuration with a full octet of (8) electrons.

If it is a clear spring day, which of
the following can we say with
certainty after Earth makes one
fourth of a full revolution?
A. It will be night.
B. It will be summer.
C. It will be cloudy.
D. It will be autumn.
On a clear spring day, we may declare with certainty that Earth completes one-fourth of a full rotation after which summer will begin.
What is a day, exactly?The duration of the Earth's complete rotation with regard to the Sun is one day. This corresponds to 24 hours, 1440 minute, or 86,400 seconds on average. The term "day" is frequently used in daily speech to refer to a sunny day, that is the interval between two solar comorbid, or the times the Sun is at its greatest position.
Are there two days every other day?If something occurs every second or every other day, for instance, it occurs one day, then doesn't occur the following day, then occurs the following day, and so on.

Draw the product for each of the following SN2 reactions: (a) (S)-2-Chloropentane and NaSH (b) (R)-3-Iodohexane and NaCl (c) (R)-2-Bromohexane and NaCN (d) 1-Bromoheptane and NaOH
The product for each of the following SN2 reactions
The SN2 reaction is a nucleophilic substitution process in which a bond is broken and a new one is simultaneously created. The step in the reaction that determines rate involves two reacting species.
The substrate is attacked from behind in this reaction by the nucleophile. The angle between the nucleophile and the carbon-leaving group bond as it approaches the chosen substrate is 180o. Through a transition state, the carbon-leaving group bond breaks and the carbon-nucleophile bond forms concurrently.
The leaving group is now forced out of the transition state on the other side of the carbon-nucleophile link, resulting in the formation of the necessary product. The product is created by inverting the tetrahedral geometry at the central atom, which is a crucial fact to remember.

If molecules of hydrogen, nitrogen, oxygen and chlorine have the same kinetic energy which molecule will be moving the fastest?
Hydrogen molecules will move the fastest if their kinetic energies are equal to those of nitrogen, oxygen, and chlorine molecules.
Which element—oxygen or hydrogen—has more kinetic energy?Boltzmann and Maxwell have also examined the dispersion of gas speed, although this is outside the purview of this course. You may have noticed that for oxygen and hydrogen gas to share the same average kinetic at the same temperature, their average speeds must be 4 times greater than each other.
What molecules will travel more quickly?As the temperature increases, the particles amass kinetic energy and accelerate.. Both their mass and the temperature affect the particles' real average speed; heavier particles move slower than

Which of the following will affect the vapor pressure of a pure molecular substance? Select all that apply.
Multiple select question.
The strength of the intermolecular forces
The structure of the substance
The temperature
The vapour of a pure chemical substance depends on the level of a intermolecular forces, that substance's structure, and the temperature.
What are instances of intermolecular forces?Between molecules, intermolecular forces are at work. In contrast, molecules themselves exert intramolecular pressures. In comparison to intramolecular forces, intermolecular forces are weaker. The Weaker intermolecular forces, dipole-dipole interaction, ion-dipole communication, and van der Waals forces are a few examples of intermolecular forces.
What causes intermolecular forces?Electrostatic in nature, forces between molecules result from the interaction of positive and negative charges entities. Forces between molecules are the total of both attracting and repulsive elements, similar to held together by covalent connections.
