Answer:
CH4 - Methane
B2Si - Diboron monosilicide
N2O5 - Dinitrogen pentoxide
CO2 - Carbon dioxide
Explanation:
When it comes to naming covalent compounds, there are several rules.
The name is derived based on the formula. For example, N2O5. The first element is nitrogen. To the name of the element, you add the prefix that tells us how many of its atoms are in the compound. In this case, there are two atoms, which means that the prefix will be di- (dinitrogen). The second element is oxygen. You are supposed to take only the root of the second element's name and then add the prefix denoting the number of its atoms and the suffix -ide (pentoxide). This is how we'll get dinitrogen pentoxide.
The only exception is methane (CH4), which is an organic compound. Organic compounds are named using the IUPAC nomenclature.
Populations in the deep-sea vent ecosystem can get energy storage molecules without sunlight. Do you agree or disagree with this claim? Explain your answer.
Answer:
Agree
Explanation:
The deep-sea vent ecosystem gets energy storage molecules without sunlight. Life in the vent ecosystem relies on alternate energy through the use of hydrogen sulfide present in the water emanating from the vent.
The producers that form the basis of the food chain are bacteria that use the hydrogen sulfide to create energy-rich molecule in a process known as chemosynthesis.
The equation of the chemosynthesis is as below:
[tex]CO_2 + 4H_2S + O_2 --> CH_20 + 4S + 3H_2O[/tex]

Anita was using steel to make rusted sculptures. After building each sculpture, she caused the steel in the sculpture to rust by placing it into a tub filled
with salt water for eight hours. Anita wondered if steel would rust faster submerged in vinegar instead of salt water. To find out, Anita cut ten squares of
steel sheet metal and split them into two equal groups. She put one group of squares into a tub filled with salt water and the other group of squares
into a tub filled with vinegar. Once an hour for eight hours, Anita counted the number of rusted steel squares in each group.
What is the manipulated independent variable in Anita's experiment?
Answer:
The type of liquid in the tub (salt water or vinegar)
Explanation:
The manipulated independent variable in Anita's experiment is the type of liquid in the tub.
The independent variable is the controlled or manipulated variable in the course of an experiment. It can also be referred to as the 'cause' variable which has the capacity to produce 'effects' on another variable - the dependent variable.
In this case, the type of liquid the tub is filled (salt water or vinegar) will hypothetically affect the rusting period of the steel. Hence, the dependent variable is the type of liquid the tub is filled while the dependent variable would be the time it takes for the steel to get rusted.

Mitochondria are found within: A) All prokaryotic cells B) A cell's plasma membrane C) A cell's nucleus D) Eukaryotic cells E) None of these answers are correct
Answer:
The correct answer is - D) Eukaryotic cells.
Explanation:
The mitochondrion is found in all eukaryotic organisms with the exception of a few. It is a double-membrane-bound organelle within the cytoplasm of the cell that takes in nutrients, breaks them down, and creates energy that makes it the powerhouse of the cell.
It turns the chemical energy from nutrients in the cell to generate energy in a form usable to the host cell which is ATP. Prokaryotic cells lack mitochondria and other double membrane-bound organelles and it s found outside of the nucleus in the eukaryotic cells.

what does light emission(color) tell us about elements?
Answer:
The color of the light emitted depends on the energies of the photons emitted, which are in turn are determined by the energies required to move electrons from one orbital to another. Those colors are as distinctive to each element as fingerprints are to people. Hope this helps
Answer:
The color of the light emitted depends on the energies of the photons emitted, which are in turn are determined by the energies required to move electrons from one orbital to another. Depending on the element you put in the flame, various different energies of photons (colors) will appear. Those colors are as distinctive to each element as fingerprints are to people.

Chemical and physical element properties are determined by their valence electrons. How do you describe metals with only one valence
electron?
A .highly reactive
B. poor conductors of electricity
C. reactive with other metals
D. likely to gain more electrons
Answer:
B
Explanation:
Chemical and physical element properties are determined by their valence electrons metals with only one valence electron are poor conductors of electricity. Option B is correct.
What are valance electrons?Valence electrons are the electrons present at the valance shell or orbit of the atom and always take part in the chemical reaction or reaction with other metals and can conduct electricity.
If the atom contains only one valance electron in the outermost shell or valance shell then it cannot conduct the electricity properly due to the fewer number of electrons.
Therefore, Option B is correct. Chemical and physical element properties are determined by their valence electrons metals with only one valence electron are poor conductors of electricity.

Maggie has 4 binders with 30 stamps in each binder. She has 3 binders with 36 baseball cards in each binder. If she gives away 45 stamps to a friend, how many stamps and cards does she have left? Maggie has stamps and cards left.
Answer:
The number of stamps and cards Maggie has left if she gives 45 stamps to a friend is 183
Explanation:
If Maggie gives 45 stamps to a friend, you must calculate the number of stamps and cards she has left.
You know Maggie has 4 folders with 30 stamps in each folder. So the number of stamps she owns is calculated as:
4 folders*30 stamps in each folder= 120 stamps
If Maggie gives 45 stamps to a friend, then the number of stamps she has left will be calculated as the difference (the subtraction) between the stamps she owned and the ones she gives away:
120 stamps - 45 stamps= 75 stamps
On the other hand, she has 3 binders with 36 baseball cards in each binder. So the number of cards she owns is calculated as:
3 binders * 36 baseball cards in each binders= 108 baseball cards
The number of stamps and cards you have left is calculated as:
75 stamps + 108 baseball cards= 183
The number of stamps and cards Maggie has left if she gives 45 stamps to a friend is 183

The solution becomes completely blue after 8 minutes. What does this represent about the type of change happening in the container
The question is incomplete, the complete question is;
Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. What does this represent about the type of change happening in the container? A chemical change started immediately and finished at eight minutes. A non-chemical change started immediately and finished at eight minutes. A chemical change occurred at four minutes. A non-chemical change occurred at four minutes.
Answer:
A chemical change started immediately and finished at eight minutes.
Explanation:
A chemical change is one in which a new substance is formed. One of the indicators that a chemical change has occurred is the change in the color of the system from red to blue.
The question clearly stated that the change occurred gradually. This means that the reaction must have started immediately the substances were mixed and went on to conclusion after eight minutes when the complete blue color appears.

What will oxygen likely do to complete its outermost shell, based on the Lewis dot diagram shown?
accept electrons
accept some electrons and give up other electrons
move electrons from the inner shell to the outer shell
give up electrons
Answer:
A. Accept electrons
Explanation:
The octet rule states that 8 electrons stabilizes a molecule. This means that oxygen will try to fill the two empty spots with electrons from other molecules. The Lewis Dot diagram shows these two empty spots with the empty circles at the bottom.
Lewis dot structures, also known as electron dot structures, are schematics that show the interatomic chemical bonds in a molecule. Additionally, they show how many lone pairs there are overall in each of the atoms that make up the molecule. Here 'O' accepts electrons. The correct option is A.
The electrical structures of the elements, especially the electron pairings, are reflected in the Lewis dot structures. Lewis structures can be viewed as "electron bookkeeping" and are a helpful approach to condensing some bonding-related information. Each dot in a Lewis dot structure corresponds to 1 electron.
Group 6 member oxygen still requires two additional electrons to complete its outer shell and remain stable. According to the octet rule, an object needs 8 valence electrons in the outer shell to be stable.
Thus the correct option is A.

A scientist built a computational model to investigate what happens when magma comes into contact with the ground surface. In the model, the ground surface was 293K, whereas the magma was 1,500K. The model examined different depths of the magma away from Earth's surface and toward the core. Over a greater amount of time, more magma cooled. What form of heat transfer accounts for the magma cooling?
Answer:
Conductive heat transfer is most likely responsible for the cooling of the magma
Explanation:
The Earth's core is continuously cooling due to human's digging, allowing for more space and heat escape from the Earth's core. All magma closer to the core would have its heat absorbed by the core, hereby increasing its coolness.
This heat transfer process is common to conduction.

1. Explain how you think changing in the thickness or length of the nail will affect the strength of the electromagnet
Answer:
I believe- If there is more metal for the magnet to reach for, then the strength will grow but it may be harder to pick up off of a surface depending on the weight of the nail. If it is a light nail, it would be more efficient for a quick result in having the magnet to pick it up
Explanation:
Answer:
Ferromagnetic materials make the magnet stronger than non-ferromagnetic materials like paper, wood, or air. A wider nail will make the magnet stronger. Making the nail longer will not make the magnet stronger, unless you also add more turns to the coil.
