Answer: 1 mole ➡️ 6.022×10²³ atoms of si.
X mole ➡️ 2.8×10²⁴ atoms of si.
X = 2.8×10×10²³/6.022×10²³
= 28/6.022
= 4.65 moles.
Explanation:
The answer is addition polymerization.
That is addition polymerization is the type of polymerization reaction involves the bonding of monomer molecules by the movement of electrons from a multiple bond into new single bonds between molecules.
Addition polymerization reaction is the reaction in which bonding of monomer molecules takes places by the movement of electrons from a multiple bond into new single bonds between molecules.
Answer:
it is not clear
but I think you are mean a oxidation state for element or compound ( molecule )
like -4 in [Cr(CO)4]4−
