Fuel pellets are used in modern energy-saving wood stoves. If the pellets used for these stoves release 742 cal/g, how many calories of energy will be released by combustion of an entire 40 lb sack of pellets?
Chapter 7.3 Intermolecular Forces: attractive forces between neighboring molecules -> London Dispersion, Dipole-Dipole, Hydrogen Bonding, and Ion-Dipole Van der Waals: attractive forces that act between atoms of molecules in a pure substance -> London Dispersion, Dipole-Dipole, Hydrogen Bonding London Dispersion Forces: coulombic attractions between instantaneous dipoles of molecules that is present in all molecules. larger molecule -> more polarizable -> stronger london dispersion force stronger force -> more attached -> higher boiling point
