Explain the environmental benefits of recycling paper products.
Answer:
:)

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

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.

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.
