An empty 10 mL volumetric flask weighs 10.268 g . After filling to the mark with distilled water at 20 °C, the mass is 20.223 g . What is the true volume of the volumetric flask at 20 °C? Be sure to correct for buoyancy.

where are the choice options?

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.
