The analysis of a hydrocarbon revealed that it was 85.6281% C and 14.3719% H by mass. When 1.69 g of the gas was stored in a 1.1 L flask at −47.8551◦C, it exerted a pressure of 513 Torr. What is the molecular formula of the hydrocarbon?

they are made of gases.

they have a spherical shape.

they make energy through fusion.

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.
