10. You're preparing for a camping trip. you see two different stoves you can pack for your trip to do
all your cooking. Which fuel would you prefer to carry?
One stove uses fuel propane.
The other stove uses naphtha (hexane) fuel.
Start by writing a balanced combustion equation for both of these reactions. Use either standard
enthalpies of formation or bond energies to determine the enthalpy changes for the combustion of
these two fuels. Then suggest which stove, the one that uses propane or the one that uses naphtha,
would you recommend to pack for your camping trip? Explain. (You may need more space for

- hat does temperature measure? Are the molecules in a beaker of warm water moving at the same speed as the molecules in a beaker of cold water? Explain? What is heat? Is heat the same as temperature?arrow_forwardIn chemical reactions, heat is converted into chemical energy (the potential energy stored in chemical bonds) or vice versa. Bond energy is the energy required to break one mole of the bond in the gas phase. Since it takes energy to break a bond, bond energies are always positive. Conversely, energy is released when bonds are formed. Thus, the enthalpy change for a reaction can be approximated from Part A Calculate the bond energy per mole for breaking all the bonds in methane, CH4.

- 3. Carbon atoms will bond with each other to form a chain, often with the peripheral atoms being hydrogen. These compounds, hydrocarbons, are organic compounds composed only of carbon and hydrogen. However, when hydrogen atoms are substituted with other elements, such as fluorine, this changes the properties of the molecule. Methylfluoride (CH3F), a substituted hydrocarbon, is used in semiconductor processing. Figure 1 depicts an incorrect Lewis structure for CH3F.
