Given the following information, calculate ΔH° (in kcal mol-1) for:  CaI2(s) → Ca+2(g) +2 I-(g)

Process  ΔH° (kcal mol-1)
Ca(s) → Ca(g)  +178
I2(g) → 2 I(g)    +36 (per mole I2)
I2(s) → I2(g)    +15
Ca(g) → Ca+(g) + e-  +590
Ca+(g) → Ca+2(g) + e- +1145
I(g) + e-→ I-(g)   -71
Ca(s) + I2(s) → CaI2(s)  +534 (per mole CaI2)  

◦ 1359 kcal mol-1
◦ 1270 kcal mol-1
◦ 2356 kcal mol-1
◦ 1572 kcal mol-1
◦ 1288 kcal mol-1

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
