Urgent , ?
two electrons are found in the same atom. one has the quantum number set (2, 1, 0, +½), and the other has the quantum number set (2, 0, 0, +½). they share the:

a. same sublevel, but are in different orbitals.
b. same orbital, but have different spin directions.
c. same energy level, but are in different sublevels.
d. same type of sublevel, but are found in different energy levels.

explanation:

i think option no d is the correct answer

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
