can someone help me with it?
Follow these steps:
Carefully measure out 3 Tablespoons of cold water into the jar.
Now measure out 1/8 teaspoon of salt and put it into the jar with the water. Put the lid on the container and shake it. Keep shaking until the salt is completely dissolved. To determine whether it has completely dissolved, hold the container up to the light and look carefully at the bottom, or open the lid and look into it. If you see little grains of salt there, it is not completely dissolved, so keep shaking until it looks the same each time you look.
If the salt does not dissolve completely after five minutes of vigorous shaking, write this in your notebook and go on to step 4. If the salt dissolves completely, add another 1/8 teaspoon of salt and repeat the process. Repeat over and over, keeping track of how many 1/8 teaspoons you add. Stop when you can’t get the salt to dissolve no matter how hard or long you shake the container.
Record how much salt you were able to dissolve in the 3 Tablespoons of water in the solubility data table.
Repeat steps 1-4, but this time using very warm or hot water. Before you do it, run the jar under hot water to warm it up so the water doesn’t cool off right away. Be sure to use the same amounts of water and salt as you did the first time. The only variable should be the temperature of the water.
Record your results, and then compare them with your previous results.
Were there any differences in the amount of salt that dissolved in the warm water versus the cold water?
Answer:
Alot of salt dissolved in warm water than in cold water
Explanation:
This is because cold water does not dissolve alot of salt and hot water dissolves alot of salt because of the kinetic energy acting on the liquid

Unit 5 - Chemical Reactions
Chemical Change/Law of Conservation
1. What is the law of conservation of mass?
Observing Chemical Change
2. How can Changes in Matter Be Described?
3. How do you identify a chemical reaction?
Describing Chemical Reactions
4. What information does a chemical equation contain?
5. How is mass conserved during a chemical reaction?
6. What are three types of chemical reactions?
Controlling Chemical Reactions
7. How do reactions get started?
8. What affects the rate of a chemical reaction?
Answer:
1. The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to gas but its mass does not change.
2. There are two types of change in the matter: physical change and chemical change.
3. Change in the arrangement of Chemicals
4. A chemical equation consists of the chemical formulas of the reactants (on the left) and the products (on the right). The two are separated by an arrow symbol (read aloud as yields). Each individual substance's chemical formula is separated from others by a plus sign.
5 During the rearrangement of atoms mass is conserved unless u add more substances

Answer:
C. Kinetic Energy
Explanation:
Use kinetic molecular theory to describe the changes in temperature, particle motion, and kinetic energy when thermal energy is added to solid chocolate. Be sure to explain the process by describing how the particles in chocolate move relative to each other in both the solid and liquid state, as well as what happens during the phase change. Then describe the changes in particle motion, temperature, and kinetic energy when liquid chocolate is poured into a mold.
Please Do a C.E.R
Claim
Evidance
Reasoning
Answer:
Matter is made up of particles that are constantly moving.All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy.The temperature of a substance is a measure of the average kinetic energy of the particles.A change in phase may occur when the energy of the particles is changed.There are spaces between particles of matter. The average amount of empty space between molecules gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases.There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together. These attractive forces are called intermolecular forces.

Section II: Observations and Conclusions
Use your answers from questions 3 and 4 (above) as the basis for the second section of your lab report. This section provides your reader with charts, tables, or drawings from the lab. You also need to incorporate your answers to the follow-up questions (from the Student Guide) in your conclusions.
Overall
When complete, the lab report should be read as a coherent whole. Make sure you connect different pieces with relevant transitions. Review for proper grammar, spelling, punctuation, formatting, and other conventions of organization and good writing.
Answer:
Which evidence from the text best supports the answer to Part A?
“Solar panels do not give off harmful gases. They do not produce toxic chemicals. So pollution levels will drop. Big cities will have less smog. There will be fewer health problems from breathing dirty air. Rivers and streams will also be less contaminated. Drinking water will be cleaner. Wildlife will flourish.”
“For example, solar energy is championed by scientists. More than a dozen professors, engineers, and academics participated in the study cited above. They stated that the ‘main goal’ of American solar policy should be ‘a massive scale-up of solar generation...’"
“Power blackouts will be less common. Spikes in electricity prices will disappear. There won’t be as many noisy power plants. Fewer ugly oil rigs will dot the landscape. And Californians will be proud that their state is leading the way in protecting the planet.”
“Workers will have to build solar panels. Truck drivers will have to deliver them. Some technicians will have to install them. Others will have to maintain them. All of these people will earn good wages. And as they spend those wages, they’ll support other businesses. That will create a positive economic ripple effect.”Explanation:
answer:
Today we learned about how human activities affect freshwater resources, during the assignment we learned about several things that could affect water quality. By watching videos and also participating in adding stuff into water to see the levels you would get. Learning about the water levels and how they can be affected by certain things were a little bit easier with the interactive assignments. I think using a regular table graph would help and would be the most effective way to get and give information. And if i could improve my lap assignment i would make it more clearer to understand and maybe make more sense.

Day 2 of answering random questions i get asked in my classroom:
How does an Ecosystem Function?
When left to itself, an ecosystem functions like a well–oiled machine. The plants and animals that live in an ecosystem depend on each other for life; this means they are interdependent. Each individual life form does its part to provide for the other lives in the ecosystem community. Let us look at the ocean ecosystem again and start at the beginning. All living things need energy to survive. For example, the seaweed in the ocean gets its energy from the sun. There are fish, like sea carp, that eat the seaweed. The carp get their energy from eating these plants. Then, there are other fish that eat the carp. For example, a sea bass may eat the carp, and a shark may eat the sea bass, and so on. This is called a food chain or a food web. Each part of the chain is connected. Each part depends on the next for the energy to survive.
Answer:
Yes! That is correct.
Explanation:
An ecosystem is one that works on it own, though each individual plays its part.
