Predictions about the future based on the position of planets is an example of physics biology earth science pseudoscience
Answer:
Pseudoscience
Explanation:
Predicting the future based solely on the position of the planets is an example of pseudoscience.
Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.
Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.
Any other statement or belief that is not based on these procedures is said to be pseudoscientific.
Answer:
The answer to your question is pseudoscience.

List and describe all five types of chemical reactions. thx.
Answer:
combination, decomposition, single-replacement, double-replacement, and combustion.
Explanation:
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:
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.

What is the subscript for carbon in this molecule?
Answer:
3
Explanation:
Subscript basically tells you the number of element or ions present in a compound. In this case the subscript of carbon which is 3 denotes that only three carbon atoms is present in the compound.
A car covers a distance of 22.75 km in 17.04 minutes. Use dimensional analysis to calculate its speed in meters/second. Do not enter units in your answer.
Round to the tenths place or further.
The speed of the car = 22.25 m/s
Further explanationGiven
A distance of 22.75 km
Time = 17.04 minutes
Required
The speed (in m/s)
Solution
Speed is the ratio of distance per time
Can be formulated :
v = d/t
v= speed, m/s
d=distance=m
t=time,s
Input the value :
[tex]\tt v=\dfrac{22.75~km}{17.04~minutes}\times \dfrac{1000~m}{1~km}\times \dfrac{1~minute}{60~second}\\\\v=\boxed{\bold{22.25~m/s}}[/tex]
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 .

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.
