Predict the number of each atom needed to form a molecule of potassium sulfide.

2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.

Explanation:

∴ Every 1.0 molecule of K₂S composed of 2.0 atom of K and 1.0 atoms of S.

So, 2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.

h let me think

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.
