2fecl3 > 2fecl2 + cl2 (fe3+ changes to fe2+) (cl- changes to cl) 1. this equation shows that fe3+ (reduced or oxidzed) 2. this equation shows that cl- is (reduced or oxidized) 3. can this redox reaction take place? (yes or no)

The correct options are as follows: 
1. In the chemical equation given above, Fe3+  IS REDUCED.
A reduction is a process in which an atom of an element gains an electron and therefore become reduced. In this type of reaction, the positive character of the atom is reduced. Looking at the equation given above, you will notice that, the positive character of Iron is reduced form +3 to +2.

2. In the reaction given above, the chlorine atom is OXIDIZED.
An oxidation is a process in which an atom loses an electron, thereby increasing its oxidation number. In this case, the positive character of the atom is increased. Looking at the chlorine atom given above, you will notice that it has a charge of -1 before and now it has change to neutral, which means that, it has given out the electron it gains earlier.

3. This type of redox reaction can not take place. This is because, in chemical reaction, the chlorine atom is always looking for another element that will donate an electron to it in order to become stable. Thus, chlorine atom easily gain electrons but it can not donate an electron to another element.

Olá. porque a reação na temperatura é muito rapida a do copo : )
