HWW Item 810

Part A

Titanium reacts with iodine to form titanium(III)iodide,emitting heat.
2Ti(s)+3I2(g)→2TiI3(s)ΔHorxn = -839 kJ

Determine the masses of titanium and iodine that react if1.50×103 kJ of heat is emitted by thereaction.Express your answer to three significant figuresand include the appropriate units.

m(Ti)= (value)(unit)

m(I2)= (value)(unit)

Part B

Consider the following generic reaction: A+2B→C+3D, withΔH = 128 kJ . Determine the value of ΔH for eachof the following related reactions.

a) 3A+6B→3C+9D

ΔH = _____ kJ

b) C+3D→A+2B

ΔH = _____ kJ

c) 1/2C+3/2D→1/2A+B

ΔH = _____ kJ
