1)Consider that coastal towns experience cooler summers than do towns further inland. Use your knowledge of heat energy, specific heat, and heat transfer to explain this fact.
2)Propane (C3H8) combusts in the presence of oxygen to produce water vapor and carbon dioxide. This reaction releases 2038 kJ per mole of propane. Write the thermochemical equation for this reaction. What does this equation tell us about the reaction?

3. Given the following equations, calculate the ΔH of reaction in which ethylene (C2H4) reacts with hydrogen gas to produce ethane gas (C2H6). Be sure to show each step of your work. Begin by writing out the target equation.
C2H4 (g) + 3O2 (g)-->2CO2 (g) + 2H2O (l) ΔH = -1411. kJ/mole
2C2H6 (g) + 7O2 (g) --> 4CO2 (g) + 6H2O (l) ΔH = -3120. kJ/mole
2H2 (g) + O2 (g) --> 2 H2O (l) ΔH = -568.8 kJ/mole
