Sari is studying four different samples of materials. this table shows the mass and volume of the samples

answer; natural resources;

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.

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