The Bay of Fundy in Nova Scotia, Canada is reported to have the largest tides in the
world with high tide and low tide occurring two times per day. The tides can measure
ft
in height. At the Hopewell Rocks at Hopewell Cape,
over approximately 50.0
on a specific day height increase was recorded as a rate of 6.08 feet per hour. What

The compound cyclohexanol, C6H120, is a good fuel. It is a liquid at ordinary temperatures. When the liquid is burned, the reaction involved is
2 C6H120(t) + 17 02(g)→12 CO2(g) + 12 H20(g)
The standard enthalpy of formation of liquid cyclohexanol at 25 °C is -348.2 kJ mol-1; other relevant enthalpy of formatton values in kJ mol1 are:
C6H120(g) = -286.2 ; CO2(g) = -393.5 ; H20(g) = -241.8
(a) Calculate the enthalpy change in the burning of 3.000 mol liquid cyclohexanol to form gaseous products at 25°C. State explicitly whether the reaction
is endothermic or exothermic.

(b) Would more or less heat be evolved if gaseous cyclohexanol were burned…
