Hee Sun drew an electron dot diagram of a silicon atom as shown. S i with 1 dot each above, right, below, left. In addition to changing the symbol to C, how would this diagram compare with an electron dot diagram of a carbon atom (C)? The dot to the left of the symbol would be removed in the diagram for carbon. The same number of dots would appear in the diagram for carbon. There would be two dots above and to the right of the symbol in the diagram for carbon. The single dots would be replaced with two dots on each side of the symbol in the diagram for carbon
(sry if doesnt make sense lol)
Answer:
B: The same number of dots would appear in the diagram for carbon.
Explanation:
The same number of dots would appear in the electron dot diagram for carbon. Therefore, option B is correct.
What is the lewis electron dot diagram?A lewis electron dot structure of an element or molecule can be used to represent the number of bonds, the bonded atoms, and the lone pairs remaining in the atoms in the molecule.
Lines can be used to show between atoms that are bonded with each other and excess electrons can be represented as dot pairs and denoted in front of the atoms.
The valence electrons of each carbon atom are equal to four from the electronic configuration of the carbon atom. As the valence electrons of each Silicon atom are equal to four from the electronic configuration of the silicon atom.
Both silicon and carbon belong to the same group so they have the same number of valence electrons. Therefore, the same number of dots will appear in the electron dot diagram for carbon.

An example of the transfer of energy between systems through work is the expansion of gas in a steam engine or car piston. Explain the energy transfer process.
A) Steam engines and pistons both expand as pressure is exerted within them and they go on to accomplish work like moving a train.
B) Energy is converted to work as the expansion of the steam engine occurs and the gas collides with the internal steam engine parts.
C) The rapidly moving particles of the expanding gas is doing work on the piston and energy is transferred from the gas to the piston.
D) The quick moving parts of the expanding steam engine is doing work on the piston and energy is transferred from the engine to the piston.
Answer:
C is the answer because since it's chemistry particles expanding would most likely be your answer
The energy transfer process is rapidly moving gas particles which are expanding doing work on piston and energy transferred from gas to piston according to first law of thermodynamics.
What is first law of thermodynamics?First law of thermodynamics is related to law of conservation of energy along with distinguishing between transfer of energy.According to this law, total energy of an isolated system remains constant.
It only gets transformed from one form to another.It puts in action the flow of energy across boundaries separating system from its surroundings.
Classic example of first law of thermodynamics is steam engine .It operates in a cyclic fashion with piston moving up and down with each cycle.Steam is fed into cylinder in first half of cycle and for second half of cycle it is allowed to escape. Work done in one complete cycle,is the difference between absorption of heat at high temperature and it's exhaustion at lower temperature.

What should the student do in her investigation to produce these results?
A) She should place a positively charged rod near the left sphere.
B) She should place a negatively charged rod near the left sphere.
C) She should place two negatively charged rods near each sphere.
D) She should place two positively charged rods near each sphere.
Answer:
A. To make the negatively charged particles attract to something else than the other sphere, then do A.
Explanation:
According to the forces of attraction,the student should place a negatively charged rod near the left sphere.
What are forces of attraction?Forces of attraction is defined a force by which atoms present in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart from each other . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

Why are spines considered a physical characteristic adaptation in cactus?
a cactus with sharp spines
The spines make the cactus look taller.
The spines protect the cactus from animals.
The spines allow for easier photosynthesis.
The spines are the seeds of the cactus.
Answer:
Explanation:
Spines are considered a physical characteristic adaptation in cacti because they help the plant to survive in its dry and hot environment.
The spines serve to protect the cactus from herbivores and other animals that might eat or damage it. They also help to regulate the temperature of the cactus by reducing the amount of sunlight that hits its epidermis. Additionally, the spines help to reduce water loss by minimizing the amount of surface area over which water can be lost through transpiration. Thus, spines are an important adaptation that enables cactus plants to survive and thrive in their harsh and arid environments.

Which graph best supports the claim that the gravitational force between two point masses is a function of the distance between the masses?
A) A
B) B
C) C
D) D
Answer:
C.
Explanation:
To make this easier, Mathematically, a function is a straight line (linear) that goes through the origin.
Graph B best supports the claim that the gravitational force between two point masses is a function of the distance between the masses. Therefore, option B is correct.
Which graph shows the given situation?The graph that best supports the claim that the gravitational force between two point masses is a function of the distance between the masses and is a hyperbolic curve with an inverse square relationship.
Therefore, the graph that shows the force of attraction between two point masses (y-axis) plotted against the distance between them (x-axis) in a hyperbolic curve with an inverse square relationship is the one that best supports the claim.
This graph should show a decrease in the force of attraction as the distance between the masses increases, and the curve should become steeper as the distance decreases. Hence, option B is correct.

Part 1: Which process does arrow A represent?
Part 2: Which type of energy transformation does arrow A represent?
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Use complete sentences to explain your answer.
Answer:
1) The process arrow A represents is photosynthesis.
2) Arrow A represents light energy transformation. Light energy from the sun is converted into chemical energy in plants.
3) Photosynthesis is part of a carbon recycling process in the carbon cycle. Plants absorb light energy and convert it to chemical energy. Plants absorb carbon dioxide which is exhaled by humans and animals. Plants then produce oxygen which is absorbed by humans and animals. Animals also eat plants thus passing the carbon compounds along.
