what are the choices?

it's filtration, but this is an assumption so my apologies if i got this

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
