3. Calculate the density of iridium given it is face-centered cubic and has a length of sqrt(2)d. Where d = x m
11.29 kg/ L

4. Predict in order of increasing vapor pressure H2O CCl2H2 C2H2

5. A calorimeter contained 75. 0 g of water at 16. 95 C. A 93
A calorimeter contained 75.0 g of water at C. A 93.3 g sample of iron at C was placed in it, giving a final temperature of C for the system. Calculate the heat capacity of the calorimeter. Specific heat of Fe is J G-1C-1

6. Calculate the ΔHO of the conversion of diamond to graphite given:
Cgraphite + O2 → CO2 ΔHO = KJ
Cdiamond + O2 → CO2 ΔHO = KJ

7. Calculate the heat of reaction for this equation:
C2H2 (g) + (5/2) O2 (g) → 2 CO2 (g) + H2O (l)
Heats of formation:
C2H2 (g) = kJ/Mol
CO2 (g) = kJ/Mol
H2O (l) = kJ/Mol

8. In the Haber process for the manufacture of ammonia at what temperature will the reaction become spontaneous?
N2 + 3H2 → 2NH3 where ΔH = -93 kJ/mol
ΔS = -198 J/mol K
