Question 1

How much heat is liberated at constant pressure when 1.17 g of potassium metal reacts with 5.66 mL of liquid iodine monochloride (d = 3.24 g/mL)?
2K(s) + ICl(l) → KCl(s) + KI(s)
ΔH° = –740.71 kJ/mol
 


◦ 2.22 × 103 kJ
◦ 8.37 × 101 kJ
◦ 1.06 × 102 kJ
◦ 1.11 × 101 kJ
◦ 7.41 × 102 kJ

Question 2

How much heat is required to raise the temperature of a 6.69-g sample of iron (specific heat = 0.450 J/g°C) from 25.0°C to 79.8°C?

◦ 2.95 J
◦ 367 J
◦ 815 J
◦ 987 J
◦ 165 J
