Titanium reacts with iodine to form titanium(iii) iodide, emitting heat, via the following reaction: 2ti(s)+3i2(g)→2tii3(s),δhorxn=−839k j you may want to reference (pages 267 - 270) section 6.6 while completing this problem.

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

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.

a electronegativity decreases beacuse the size of nucleus is bigger.
