Sahil watched a demonstration in which a scientist combined two substances in a sealed container and analyzed the results. The ending substances did not look the same as the starting substances.Sahil was given a diagram with the repeating groups of atoms that make up the starting substances, plus information about the properties of the starting and ending substances. He created a model of the repeating groups of atoms that might make up the two ending substances.Does his model correctly show why the properties of the ending substances are different from the properties of the starting substances? Describe what could be correct or incorrect about his model.
This model correctly show the chemical reaction that take place in this model.
Is this model show correctly the process?This model correctly show the properties of the ending substances that are different from the properties of the starting substances because the properties of product are different from the reactants.
So we can conclude that this model correctly show the chemical reaction that take place in this model.

Predict: Predict what you think will happen to the charges of the comb and water if the comb comes in contact with the water. Record your hypothesis before following the directions below to carry out the lab experiment. The charges would attract. How and why is what I don’t know.
Directions:
1. Turn on a faucet just enough to allow a thin stream of water to flow.
2. Have a student volunteer-run a comb through his/ her hair a few times.
3. Observe. Tell the student to hold the comb near, but not touching, the stream of water.
4. Answer all questions below in complete sentences, using the R.A.C.E. strategy.
Ask and record your findings: What do you observe? Describe. I observed the stream of water bend toward the comb. I gave the comb electric charge by passing a comb through my sister’s hair and that allowed the comb to bend the stream of water.
Ask and record your findings: What does this indicate (show)? Explain. I

Explanation:
this is the question and i dont know which reasoning i should use for the claim "If you follow the instructions, the POW kits will always heat the water above the correct temperature for pasteurization (65°C), but some people didn’t follow the instructions."
Answer:
I think this evidence supports this claim because Evidence Card b says “One man got sick, but his two children did not. He used water from Whip River. He used the cube to heat the first pitcher of water, which he gave to his kids, and then reused the cube without reheating for the second pitcher, which he drank himself.”
Explanation:
The correct reasoning for the given claim is shown by evidence 2.
What is water pasteurization?
Pasteurization is a method of disinfecting water without boiling it using heat or radiation.
Evidence 2 is the correct reasoning to explain the fact that if we follow the instructions the kit will always heat the water above the correct temperature for pasteurization (65°C). Second evidence is that “One man got sick, but his two children did not. He used water from Whip River. He used the cube to heat the first pitcher of water, which he gave to his kids, and then reused the cube without reheating for the second pitcher, which he drank himself.”
Hence evidence 2 is the correct reasoning.

An element’s properties can be predicted from _____.
the number of its neutrons
its atomic mass
its location in the periodic table
the number of its electrons
A periodic table can be used to forecast an element's properties. As we drop into a group or go across a period in the Periodic Table, we can observe a variety of patterns in the physical and chemical characteristics of the elements. The correct option is C.
Each element's location in the table provides crucial details regarding its composition, characteristics, and behavior during chemical reactions. In particular, you may determine an element's electron configuration that is, how the electrons are arranged around the nucleus by looking at where it is in the periodic table.
The group (vertical column) number in the Periodic Table can be used to calculate an element's number of valence electrons. The chemical characteristics of elements with the same number of valence electrons are comparable.
Thus the correct option is C.

Answer:
Ionic
Explanation:
Lithium is an alkali metal and form an ionic bond by donating an electron.
Fluorine is a halogen and forms ionic bonds by accepting an electron.
The electronegativity difference between lithium (0.98) and fluorine (3.98) is 3 Pauling units. Usually, when elements have a difference of 1.7 (or 2.0) Pauling units the bond is classified as ionic.

The diagram which shows the repeating groups of atoms that make up the ending substances is C.
What are repeating group?Repeating group is defined as a group of fields or attributes that show up repeatedly in a database table. It is a widespread issue that affects both big and small businesses, and it can have a variety of effects. An attribute that appears more than once in each row of a table is known as a repeating group. A relational table cannot contain "repeating groups," as they are a feature of pre-relational systems.
On most metals, a reaction could be seen when acids were applied. A gas and heat were created when the metal vanished. The new chemicals' chemical characteristics are distinct from those of the original substances.
Thus, the diagram which shows the repeating groups of atoms that make up the ending substances is C.

If organisms are being outcompeted in an ecosystem, what could they do?
Answer:
The most obvious result of the removal of the top predators in an ecosystem is a population explosion in the prey species,When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other. When the predators are removed, prey populations explode
Explanation:
Basically they try to balance each other out to the same scale got it!?If organisms are being outcompeted in an ecosystem, the competitive species have to be added to the ecosystem.
The ecosystem has been the area that has been comprised of the biotic and abiotic components that help in survival.
The biotic components in an ecosystem have been consisted of plants, animals, and decomposers that are arranged in the hierarchical order in the ecosystem. The balance between the levels of the ecosystem has been constituent of the proper ecosystem working.
When there has been out-competence in the ecosystem, the number of the species in the ecosystem grows in a large proportion that resulting in an imbalance ecosystem.
The outcompeted species in the ecosystem have been reduced or the competitive species in the ecosystem have been added in order to balance the ecosystem.
