Question

Titanium reacts with iodine to form titanium(III) iodide, emitting heat. 2Ti(s)+3I2(g)→2TiI3(s)ΔHorxn = -839 kJ Part A Determine the masses of titanium and iodine that react if 1.46×103 kJ of heat is emitted by the reaction. Part B Express your answer to three significant figures and include the appropriate units.

Answer 1

2Ti(s)+3I2(g)→2TiI3(s)ΔHorxn = -839 kJ

2 moles of Ti react with I2 gives -830 Ki

2*48 of Ti react with I2 gives = -830kj

-2*48*1.46*10³ /830 = Ti react with I2 gives -1.46*10³Kj

168.86 gm of Ti react with I2 gives -1.46*10³ Kj

mass of Ti = 169gm

b. 3 moles of I2 react with Ti gives -830kj

3*254gm of I2 react with Ti gives -830kj

3*254*1.46*10³/830 = gm of I2 react with Ti gives 1.46*10³

1340.4 gm of I2 react with ti gives 1.46810³

mass iof I2 = 1.34*10³ gm >>> answer
