Answer:
The correc answer is C. greenhouse gases.
Explanation:
The atmosphere is a layer of gases that surrounds our planet and is one of the essential elements for life on it.
The atmosphere protects us from harmful solar radiation from the Sun. The Sun, in addition to light and heat (infrared radiation), emits other radiation such as gamma rays, X-rays and ultraviolet rays that are harmful to life. These harmful radiations are absorbed by the atmosphere.
The atmosphere also protects us from the impacts of meteorites. These are from outer space are attracted by gravity and fall on the earth's surface. Upon coming into contact with the gases of the atmosphere, at high speed, the friction causes them to heat up so much that they become incandescent and end up disintegrating, avoiding reaching the ground. Only the largest (rare) can pass through the atmosphere and reach the ground.
Something similar happens that with meteorites occurs with the dangerous particles of space.
Greenhouse gases contribute, to a greater or lesser extent, to the increase of the greenhouse effect, since they are capable of absorbing the heat energy carried by long-wave radiations that are reflected by the Earth's surface.This phenomenon prevents the solar energy constantly received by the Earth from returning immediately to space and causing the temperature of the air near the ground to rise. Then there are changes in the climate such as sea level rise, changes in rainfall, disappearance of forests, extinction of organisms and problems for agriculture.
So the correc answer is C. greenhouse gases.
Answer:
Structural
Explanation:
Isomerism is the existence of two or more compounds with the same molecular formula but different molecular structures due to the difference in the arrangement of atoms or spatial orientation of atoms.
Isomers have the same molecular formula but differs in their structural arrangement.
In organic chemistry, Isomerism can orginate from different arrangement of atoms.
It can be carbon chain length known as chain isomerism. Here, the carbon length is changed and arranged in different ways.
We can also have position isomerism which entails the position of the functional group in the structure.
It can also be functional group isomerism which deals with the possible arrangement of the group on the chain.
Isomers have the same molecular formulas but different structural formulas. This different structural arrangement leads to differences in the physical and chemical properties of the isomers.
Isomers are molecules that have the same molecular formula, meaning the same number and type of atoms, but different arrangements of atoms within the molecule. Hence, isomers have different structural formulas, which are used to represent the three-dimensional arrangement of atoms in a molecule. For instance, the compounds butane and isobutane both have the formula C4H10, but in butane, all four carbon atoms are arranged in a row, while in isobutane, three carbon atoms form a branch off a central carbon atom. Therefore, the structural formulas of these compounds differ, even though the molecular formula is the same.

SIX: I don't know the chapter
The answer is: the atom with more valence electrons are in the middle of a molecule and it form more bonds.
For example, molecule hydrogen cyanide (HCN).
Lewis structure for hydrogen cyanide is H:C:::N:
Hydrogen has valence one (I), it means it has one single bond and electron configuration like closest noble gas helium.
Carbon has valence four (IV), it has four bonds (one with hydrogen and three with nitrogen) and full octet.
Nitron has valence three (III), it has full octet and electron configuration like noble gas neon (Ne).
Hydrogen cyanide has linear shape (the bond angles of 180 degrees).
Answer:
The first kind of body wave is the P wave or primary wave.
Explanation:
This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station.
