Answer:
A simple displacement reaction occurs when an iron nail is immersed to a beaker containing copper sulphate solution.
a)
Iron is more reactive than copper. As a result a displacement reaction will take place. The ferrous or Fe (II) irons will move to the solution. The copper ions (Cu II) will get deposited on the nail. This will cause the colour to change from blue to green.
b)
The equation can be written as:
Fe (s) + CuSO4 (aq) -> FeSO4 (aq) + Cu (s)
c)
A chemical change can be described as a change that causes a substance to change to another form. Hence, this reaction is a chemical change.
Thrust faulting:
type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal)

Answer:
1.25 moles
Explanation:
First, we need to balance the equation. Essentially, this means making sure we have the same number of each atom on each side.
On the left side, we currently have:
- 1 Co atom
- 2 F aomts
On the right side, we have:
- 1 Co atom
- 3 F atoms
To balance it, add a 2 to Co on the left, 3 to F2 on the left, and 2 to CoF3 on the right:
→ 
Now, we have 1.25 moles of Co, and since the ratio between Co and CoF3 is 1:1, we also have 1.25 moles of CoF3.
Thus, the answer is 1.25 moles.
Answer:
New predators and not a lot of food
Explanation:
If new predators come than they can eat the insects and go extinct. Also if there is not a lot if food than the will die because they have nothing to eat.
