PLZ HELP!!! ILL MARK BRAINLIEST!!! You read an article written by an amateur ghost hunter. It includes the following paragraph. I spent one night in the home. As soon as I entered it, I got a sudden chill, as if someone didn’t want me there. As I walked through the hall, I felt a heavy presence all around me. I measured a large amount of energy coming from the upstairs bedroom. I believe there is a ghost in the home. This ghost hunter claims that there is a ghost in the home. Is this a scientific claim? Why or why not?

How does increased temperature affect the amount of salt, carbon, and other substances able to dissolve in the ocean? What are the resulting effects?
Answers
Answer:
For solid salts that are soluble in the sea water, as the sea water temperature rises, the solubility of the salt in the water increases. The accompanying increase in the kinetic energy of solvent water molecules with the increase in the temperature of the seawater results in the increase in the number of solute salt inter-molecular bonds being broken by the energetic solvent molecules resulting in increasing solubility of the solids
However, for gases, the increase in temperature of the sea water results in a decrease in the solubility of all gases. The process is also explainable by the kinetic theory such that a rise in temperature of the gas seawater solution increases the kinetic energy of both the solvent water and the solute gas. The higher energy gases are moving much faster and are then then able to separate from the less mobile liquid gas combination.
The resulting effects
1) The surface (topmost) hotter portions of the sea have fewer living organisms
2) Fishes that come to the surface frequently gas for air by bringing their head above water
3) Most of the life forms are located deep within the sea
4) Formation of water movement cycles within the ocean and polar water bodies
5) Mechanical nature of the sea compared to fresh water bodies

Is Coca Cola a homogeneous mixture
Answers
Answer:
Yes
Explanation:
Coca Cola is a homogenous mixture, just like sugar, salt, and more. Hope this helps!
Answer: Yes
Explanation: Coca cola is a homogeneous mixture because the syrup and water are mixed evenly throughout the solution. For example, an unopened soda in a bottle has a uniform composition and is a homogeneous mixture. Once you open the bottle, bubbles appear in the liquid. The bubbles from carbonation are gasses, while the majority of the soda is liquid. An opened can of soda is an example of a heterogeneous mixture.

What is the connection between Archimedes and the Mass-Volume lab
Answers
Answer:
Explanation:
This question is not very clear, however, going by the key words in the question, Archimedes' principle shows a relationship between mass and volume.
Archemedes' principle states that when a body is fully or partially immersed in fluid, it is acted upon by an upward force which is equal to the weight of the fluid displaced by the body.
The volume displaced here can be determined using the formula
Density of liquid = mass displaced ÷ volume
Hence, volume = mass displaced ÷ density of liquid

Paper chromatography is a good way of separating coloured substances mixed together in a solution.

The solution for the given linear equation can be solved by simplifying the equation. The value of x is obtained as - 8.
What is linear equations?Linear equations are the equations which shows a linearity with a second expression which is similar to the first but having different mathematical operations and signs.
By solving linear equations we can solve for the unknown value of x. The value of x can be obtained by taking the whole expression to one side and which is having a constant value.
Given, - 3x + 7x - 8 = 34 + 9x -2.
= 4x - 8 = 32 + 9x
= 4x - 8 - 9x = 32
-5x = 40
x = - 40/5 = - 8.
Hence, solution of the given equation is -8.

PLZ HELP!!! ILL MARK BRAINLIEST!!! Would you consider the practice of "ghost hunting” to be closer to science or pseudoscience, based on the information provided in the article? Provide two examples to support your answer.
Answers
Answer:
I would consider the practice of "ghost hunting” to be closer to pseudoscience than science because the work described in the article mostly lacks process and is subjective. In the article, people looking for evidence of ghosts do not set up controlled experiments with repeated trials. Instead, they take several measurements and make guesses about what might be causing the results they see. The people in the article also base conclusions on observations such as feeling a "heavy presence” or a "sudden chill.” These are subjective observations.
