Sample Problem 6.8
Writing Formation Equations
SOLUTION:
PLAN:
(a) Silver chloride, AgCl, a solid at standard conditions.
(b) Calcium carbonate, CaCO3, a solid at standard conditions.
Use the table of heats of formation (Table 6.5) to calculate DHof values.
(c) Hydrogen cyanide, HCN, a gas at standard conditions.
DHof = -127.0 kJ
DHof = -1206.9 kJ
DHof = 135 kJ
