There are several different models that represent compounds. One type of model is shown.
A large black sphere connected to 4 small blue spheres by 4 grey sticks.
What type of model is shown?
a structural formula
a chemical formula
a space-filling model
a ball-and-stick model
For those looking for the letter its D
Your welcome :)
The representation described in the question is a ball and stick model.
Several kinds of models can be used to represent molecules. Models help us to accurately visualize what the molecule may look like. It shows the actual arrangement of atoms in the molecule in order to help us predict the possible reactions that the molecule may undergo.
A model which consists of spheres connected to each other is a ball and stick model. The spheres are the balls and they are linked to each other by the sticks.

What is radiation?
a Transfer of heat through objects touching the source
b Transfer of heat through direct physical contact
c Transfer of heat through electromagnetic waves
d Transfer of heat through the movement of particles
Answer:
C.
Explanation:
Radiation is an invisible force that can be deadly or helpful. So the only way it can move is by another invisible force.

What is the difference in the number of neutrons between an atom of fluorine and an atom of argon?
I need an answer fast PLEASE!
The difference between the number of neutrons between an atom of fluorine and an atom of argon is 12
The number of neutrons is obtained by subtracting the number of protons from the mass number of the atom. We can calculate the number of neutrons in each element given this information
Mass number of fluorine = 19
Atomic number of fluorine = 9
Mass number of Argon = 40
Atomic number of argon = 18
Hence;
Number of neutrons in fluorine = 19 - 9 = 10
Number of neutrons in argon = 40 - 18 = 22
Difference between number of neutrons in argon and number of neutrons in fluorine = 22 - 10 = 12

In your second paragraph, describe properties of sound waves. Then make a claim about how loud an explosion in space should be. Provide evidence and reasoning to support your claim.
Answer:
Here are five important characteristics: wavelength, amplitude, frequency, time period, and velocity. The wavelength of a sound wave can tell the distance that wave travels before it repeats itself. The wavelength itself is a longitudinal wave that show compression and rarefactions of sound waves.

Explain how deforestation contributes to global warming
Answer:
when trees are cut down it reduced the amount of CO2 being converted into oxygen
Answer:
Deforestation contributes to global warming because with trees being cut down there is less oxygen being made and no trees to take in the carbon dioxide that is being produced. So without trees to do the work, people build greenhouses which uses their own gas that makes the world warmer because it traps the heat from the atmosphere.
Explanation:
A wave cycle is
a. the amount of time it takes for a wave pattern to repeat.
b. the total number of waves created by a single disturbance.
c. one complete motion of the repeating pattern in a wave.
d. the total number of S-shapes created by a wave in 60 seconds.

This energy is mostly seen when the ball is kicked in the air. It is called potential energy because it has the potential to do work. If the soccer ball is raised to a certain height, at the top, before it gains Kinetic Energy, it has the Potential stored that it will be used once it starts to move.

2. A storyboard is a series of panels that shows the visual and verbal components of a video you intend to make. Create a storyboard that explains this phenomenon. It must
• be one to two minutes in length.
• demonstrate an understanding of Earth’s rotation and revolution.
• include evidence for these motions.
• include the terms: pattern, rotate (rotation), revolve (revolution), axis, Earth’s orbital plane, and Polaris.
You may use any of the aspects of the models used in class and in the Student Text.
Answer:
A storyboard is a sequence of sketches or illustrations that map out the scenes planned for a video. The video production team then uses this map to ensure that the plot is coherent, engaging, and free of inconsistencies before they start making the video.
How does an increase in altitude affect the climate?
Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

What is a phyiscal and chemical change
Answer:
Physical change is when change occur physically in a substance. It is usually reversible. It includes change in colour, shape, texture, volume etc.
Examples: Cutting of paper, making moulded stuff from dough etc.
Chemical change is when change occurs chemically in a substance. It is non-reversible. When ever a physical change happens, a new substance if formed.
Examples: Burning of paper, transformation of milk into curd etc.
