Is there a relationship between CO2 levels rising and heavy precipitation? If so, what is it?
Answers
Answer:
Explanation:
Yes, there is a relationship between rising CO2 levels and heavy precipitation. As the concentration of CO2 in the atmosphere increases, it leads to a warming of the Earth's surface due to the greenhouse effect. This warming, in turn, causes an increase in the rate of evaporation of water from the Earth's surface, including from the oceans, lakes, and rivers.
This increased evaporation results in more water vapor in the atmosphere, which can lead to heavier precipitation events, including more frequent and intense rainstorms, snowstorms, and other forms of precipitation. This is because warmer air can hold more moisture, making it more likely to produce heavy rainfall.
In addition, the warming of the Earth's surface can also lead to changes in atmospheric circulation patterns, which can further increase the likelihood of heavy precipitation events in some regions.
Overall, the relationship between rising CO2 levels and heavy precipitation is complex and can vary depending on the specific location and other environmental factors. However, there is evidence to suggest that as global temperatures continue to rise due to rising CO2 levels, heavy precipitation events are likely to become more frequent and intense in many parts of the world.
Answer: Yes there is a direct relationship between CO2 and heavy precipitation. Rising in CO2 means increasing the temperature in the atmosphere which causes more water vapor evaporates into the atmosphere and which causes high rainfall or precipitation.
Explanation: Increased atmospheric CO2 levels are causing plant stomata to close, allowing plants to hold more water in their stems, reducing transpiration, and possibly impacting tropical rainfall patterns in varying ways depending on region.
Please help me! Here's the question "Describe two ways in which bodies of water can affect climate" I really would be thankful if you can help!
Answers
Answer:
Rising temperatures, facilitated by CO2 concentrations in the atmosphere, are also warming the globe leading to the melting of ice and glaciers. The ultimate effect of these climatic conditions is the contamination of water sources – both surface and groundwater.

How many Hydrogen atoms are present in this chemical equation: 3HCl
Answers
Answer:
pls mark as brainliest!!!!!!
Explanation:
If you considering in smaller scale You can simply say that “There is One Hydrogen atom Binds with Cl atom”. But when we are using this chemicals in Labs.
We talking in Moles
Mole is a quantity defining unit. Which is larger than you couldn't Imagine. 1 mole of pebbles can covered whole surface of earth.
1Mole=6.022×1023
It means 1 mole of Hydrogen is containing 6.022×1023 atoms. Be aware “Be aware thats a Quantity defining factor” Then we can get actual ratio of chemical formula..
HCL “The chemical formula”
H : 1 “Above chemical formula containing 1 atom to binds with another species”
Cl : 1 “Clorin also same as Hydrogen”
Then, You can multiply Ratio of atom by Avagadro Constant which is we pre defined as 1 Mole.
For understand it simply This statement would be helpful.
1 mole containing, Avagadro number of atoms
Hope This would be helpful!
Answer:
the answer is going to be 3 because it asked how many atoms of hydrogen it never said how many number of atoms of hydrogen.
so,
HCl has 1 atom of hydrogen in ONE MOLE but there are 3 moles given so you multiply the atoms of hydrogen by 3 that is going to be your answer i.e. 3

How is the form of energy being changed when a student uses an electric sharpener to sharpen a pencil?
from mechanical to electrical
from electrical to mechanical
from thermal to mechanical
from magnetic to electrical
Answers
Answer:
B
Explanation:
Because the sharpener is attached to an electrical outlet
When a student uses an electric sharpener to sharpen a pencil then from electrical energy to mechanical energy. Therefore, option (B) is correct.
What is mechanical energy?Mechanical energy can be defined as the addition of kinetic energy and potential energy that is used to perform work. The total mechanical energy is conserved when the forces performing work are conservative in nature.
The principle of conservation of mechanical energy can be described as when an isolated system is under the influence of conservative forces, then the mechanical energy is constant. If a body moves in the opposite direction of a net force, the potential energy will increase and the speed of the object changes, the kinetic energy also changes.
Many devices are used to transform mechanical energy to or from other forms of energy, such as an electric motor converts electrical energy to mechanical energy,
An electric sharpener converts mechanical energy into electrical energy. Therefore, option (B) is correct.

13. Would you expect oxygen to form a cation or anion? How many electrons would it gain or lose? Why?
A)Anion, it would lose 2 electrons to satisfy the octet rule.
B)Cation, it would lose 2 electrons to satisfy the octet rule.
C)Anion, it would gain 2 electrons to satisfy the octet rule.
D)Cation, it would gain 2 electrons to satisfy the octet rule.
Answers
Answer: C)Anion, it would gain 2 electrons to satisfy the octet rule.
Explanation:
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.
The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration of oxygen with 8 electrons is
\(O:8:1s^22s^22p^4\)
The cation is formed by loss of electrons and anions are formed by gain of electrons.
In order to complete its octet and get stable, it gains 2 electrons and thus would form an anion.
\(O^{2-}:10:1s^22s^22p^6\)

Why do you think that the neutron was the last of the atom components to be discovered?
Answers
Answer:
The neutron was the last of the atomic components to be discovered because it does not have an electric charge, making it difficult to detect. It was also not predicted by early atomic theories, leading scientists to believe that the atomic nucleus was composed solely of protons. The discovery of the neutron required the development of new experimental techniques, such as neutron scattering, to detect its presence.

Answers
Answer:
Image result for explain how the burning of fossil fuels causes climate change
When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.
Explanation:
Answer:
Correct answer: B). Global climate is changing due to burning of fossil fuels and deforestation.
Forest holds a large amount of carbon, plants are known to absorb carbon dioxide from the atmosphere as they grow, that carbon dioxide is stored in plants in the form of carbon in plant's roots, leaves and in the soil. When trees are cut down, that stored carbon is released in the environment in the form of carbon dioxide, which accounts for approximately 18% of global greenhouse gas emission.
The burning of fossil fuel like coal, petroleum, oil, gas for the energy purpose is one of the major contributors for the rising level of carbon dioxide in the atmosphere, which leads to global warming and affect the climate.
Hence, the correct answer would be option B.
