When iodine crystals sublimate into iodine gas within a sealed flask, the

system will eventually reach a heterogeneous equilibrium.

Explanation:

Sublimation is the process in which substances of solids gets converted into gases. In this process of sublimation there is no occurrence of intermediate state called liquid form.

In Iodine sublimation the iodine crystals are placed in a beaker and gets heated. During this heating the crystal form of iodine is converted to gas state without interference of liquid form. This is called Iodine sublimation.

This conversion of one form of reactants to other form of products comes under heterogeneous equilibrium.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

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.
