Answer:
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Reactants are the starting materials, while products are the end result of the reaction. All chemical reactions are accompanied by a change in entropy.
In general, chemical reactions can be classified as either redox reactions or non-redox reactions. In redox reactions, there is a transfer of electrons between reactants. In non-redox reactions, there is no electron transfer. All exothermic reactions are redox reactions, while endothermic reactions may be either redox or non-redox.

Answer:
I won’t do it in paragraph form cuz it will look very choppy but here you go:
Weathering is when the weather itself changes something, like when a metal bike gets rusty after sitting outside for a long time, or when a plant grows out of concrete.
Erosion is when something gets eroded away at. Like when something has water or wind is flowing against it so much that it changes shape. This is how canyons are made.
Deposition is when a gas turns into a solid, removing energy and skipping the liquid step (frost forming on car window)

When an earthquake occurs, two different types of waves are generated. These waves are called P waves and S waves. Examine the diagram, which shows how the waves travel through Earth. Which statement provides the best evidence of Earth’s structure, based on the information in the diagram?
A. The bending of S-waves shows that Earth has both an outer and an inner core.
B. Earthquakes provide no information because they cannot be detected all over Earth.
C. S-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.
D. P-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.
Answer:
Since S-waves do not travel through liquids, the evidence shows that Earth has an outer core layer made of liquid.
Which statement about the sun's energy is correct?
A. It is entirely re-radiated back into space.
B. A part of it is destroyed by greenhouse gases.
C. A part of it is absorbed by atmospheric gases.
D. It makes Earth too hot for plants and animals to survive.
Answer:
C. A part of it is absorbed by atmospheric gases.
Explanation:
brainiest plz
The statement about the sun's energy is correct is a part of it is absorbed by atmospheric gases. Hence option C is correct.
What is atmosphere?Atmosphere is defined as the layer of gases kept in place by Earth's gravity and forming its planetary atmosphere. There are several minor layers in addition to the five major ones that make up Earth's atmosphere. The primary layers are, from lowest to highest, the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
Ozone (O3), which is present in the upper atmosphere, absorbs a sizable part of the Sun's UV radiation (the stratosphere). The Earth system does not become hotter as a result of solar radiation that Earth's surface or atmosphere reflect back into space. Heat is produced as a result of absorbed radiation.
Thus, the statement about the sun's energy is correct is a part of it is absorbed by atmospheric gases. Hence option C is correct.

In a solution of a carbonated beverage, what is the dissolved carbon dioxide?
A. the solvent
B. the solute
C. the precipitate
D.saturated
Carbonated beverage contains dissolved carbon dioxide and water, out of which water is solvent and carbon dioxide is solute and other sweeteners are also solute.
What is solution?Solution is a homogeneous mixture which contain two component that are solute and solvent . Solute is the amount of component which is in small amount whereas solvent is a component which is in large amount
Example: If we take sugar solution then the amount of sugar is small that is solute whereas water is in large quantity which is solvent. It is not necessary that water will be always solvent or liquid will be solvent, solid and gas can be the solvent too.
In a solution of a carbonated beverage, water is solvent and carbon dioxide gas is the solute as it is dissolved in water. Thus carbon dioxide is solute in carbonated beverage.
