DESCRIBE the five types of chemical reactions
(Synthesis, Decomposition, Single displacement, Double displacement, Combustion)
The study of chemicals is called chemistry.
When two elements react together to form a new compound is called a reaction.
When two-element join together to form a new compound is called synthesis.
[tex]C + O_2 --> Co_2[/tex]
The breakdown of a compound into two different elements is called decomposition.[tex]H_20 ----> H_2 + O_2[/tex]
The substitute of one element in the compound is called single displacement.[tex]Fe + H_2So_4---> FeSo_4+ H_2[/tex]
The substitute of two-element in the compound is called double displacement.[tex]BaCl + H_2So_4 + ---> BaSo_4 + HCl[/tex]
The burning of the element in the presence of oxygen is called a combustion reaction.[tex]C + O_2 ---> CO_2[/tex]
Hence, the answer is mentioned above.

Explain how natural resources are identified and why natural recourses are in evenly distributed.
Answer:
Natural resources are not evenly distributed all over the world. Some places are more endowed that others — for instance, some regions have lots of water (and access to ocean and seas). Others have lots of minerals and forestlands. Others have metallic rocks, wildlife, fossil fuels and so on.
Explanation:
How many molecules of carbon dioxide are in 12.2 L of the gas at STP?
Answer:
Converting Between Moles and Liters of a Gas at STP. To convert between moles and the volume of a gas at STP, we will use the factor label method discussed in the first unit. This conversions relies on the fact that a mole of gas at STP has a volume of 22.4 L.
Explanation:
One molecule of carbon dioxide at STP has a volume of 22.4 liters . Thus number of molecules of carbon dioxide in 12.2 L is 3.27 × 10²³ molecules.
What is one molecule?A molecule is formed by the combination of same or different kinds of atoms. A number molecules together form a compound. Water, carbon dioxide etc. are compounds.
One mole of a molecule contains 6.022 × 10²³ number of atoms. Similarly, one mole of a compound contains, 6.022 × 10²³ number of molecules.This number is called Avogadro number.
At standard temperature and pressure (STP) that is at 298 K and 1 atm pressure, one mole of any substance carry 22.4 L. Thus number moles of 12.2 L of carbon dioxide is 12.2 / 22.4 = 0.54 moles.
Number of molecules = 0.54 moles × 6.022 × 10²³
= 3.27 × 10²³
Hence, number of molecules of carbon dioxide in 12.2 L is 3.27 × 10²³ molecules.

Explain how Coulomb's law can help you understand why some interparticle forces are stronger than others.
Answer:
Coulombs equation involves distance and the distance from one radius to the next allows us to predict certain characteristics such as pull and attraction. For example, you would expect, a higher charge on the ion and a higher dipole moment causes a larger force. This is due to the magnitude which is the distance between these two and effectively that is how Columbus law comes into play.
Coulomb's law states that the force of repulsion or attraction among both two charged bodies is directly proportional to the product of their charges as well as inversely proportional to the square of the length between them.
What is Coulomb's law?An electric force is created when two charged particles collide. The forces will be greater if you have larger charges.
Coulomb's Law can be understood by combining these two ideas and the fact that charges can attract and repel each other. It is a formula for calculating the electrical forces between two objects.
Coulomb's equation involves distance, and the distance between two radiuses allows us to predict certain characteristics such as pull and attraction.
As you might expect, a higher charge on the ion and a higher dipole moment result in a greater force. This is due to the magnitude of the distance between these two, and this is where Columbus law comes into play.
Thus, this way, Coulomb's law can help you understand why some interparticle forces are stronger than others.

If you add more molecules but do not change the temperature or the pressure, what will happen to the system?
the molecules will move faster
O the volume will decrease
the volume will increase
the molecules will move slower
Answer:
the volume will increase
Explanation:
The kinetic energy of gas molecules depend upon the temperature . If temperature is increased , the molecules will move faster . When temperature is decreased , they move slower .
Hence when more molecules are added to a gas without changing its temperature , the velocity of gas molecules will remain unchanged .
Since pressure is also constant , it is volume which will be increased .
It can be explained from universal gas formula as follows
PV = nRT
P , R and T is constant ,
V ∝ n
Volume is proportional to n which depends upon number of molecules .
So volume will increase if number of molecules increases .
