Answer:
14 atoms
Explanation:
Number of atoms in Fe₂(CO₃)₃
An atom is the smallest indivisible particle that takes part in a chemical reaction.
In Fe₂(CO₃)₃; we have:
Elements Number of atoms
Fe 2
C 3
O 3(3) = 9
Total number of atoms = 2 + 3 + 9 = 14 atoms
Hey there!
<span>An example of a Destructive force is the formation of mountains.
This statement is false, an example of a destructive force would not be the formation of mountains.
Hope this helps you.
Have a great day!

The correct answer is:
Absorber
An absorber is a material that takes in a wave when the wave hits it.
The size of the disc will Increase
The hole will enlarge in proportion to the metal if the disc is homogeneous and isotropic (the same in all directions). This is evident because, since the hole's edge is constructed of metal, the thermal expansion equation dL=LdT holds true for all lengths related to the metal, including the circle of the hole. Additionally, if the diameter of the hole increases, so does its circumference.
The analysis becomes more challenging if your disc has distinct areas formed of various metal kinds or if the metal that makes up your disc has an anisotropic crystal structure, meaning that it expands by different amounts in different directions. But given the total change in size is still an expansion, I believe the hole would become bigger in all scenarios.
Hence ,The size of the disc will Increase
