The answer to that is mass and chemical
A wave.
Scientists now recognize that light can behave as both a particle and a wave.
The given statement is True.
This is single replacement reaction.
As reactivity decreases down the group,
Iodine is less reactive than Chlorine.
And so Iodine cannot replace chlorine from FeCl2.
I2 + FeCl2 ---> no reaction (Iodine is less reactive than chlorine)
C cause ur changing the identity of the material
Answer:
