Answer:
Fe is just the shortened version of Iron whereas Fe2+ is a positive ion,cation to be more specific
2K + Br2 ===> 2KBr
It's very ionic. The transfer of 2 electrons from K to Br2 is nearly as complete as it can be.
Answer:
Chemical bond
Explanation:
Chemical bond is refer to as the interaction existing between two or more atoms, ions or molecules that holds them together by decreasing the potential energy of their electrons. Chemical bond leads to the formation of chemical compounds. Chemical bond may occur as a result of the electrostatic force of attraction that exists between oppositely charged ions such as those in ionic bonds or when electrons are shared such as those in covalent bonds.
New molecules would form.
the other three are examples of a physical change
C is correct answer.
Compounds is a atoms it has a different elements combine the new molecules.
Hope it helped you.
