Solution: Titanium reacts with iodine to form titanium(III) iodide, emitting heat, via the following reaction: 2 Ti(s) + 3 I2(g) → 2 TiI3(s); ΔH˚rxn= -839 kJ. Determine the mass of iodine that reacts if 1.61×10

Titanium reacts with iodine to form titanium(III) iodide, emitting heat, via the following reaction: 2 Ti(s) + 3 I₂(g) → 2 TiI₃(s); ΔH˚_rxn= -839 kJ. Determine the mass of iodine that reacts if 1.61×10³ kJ of heat is emitted by the reaction.
