Calculate the change in mass (in kg) when one mole of pentane is combusted.  The heat of combustion of pentane is -3509 kJ/mol.

Using the provided standard reduction potentials, calculate the standard emf, E°cell (in V to two decimal places), of an electro-chemical cells utilizing the following reactions:   2 I-(aq) + Zn2+(aq)

Calculate the nuclear binding energy per nucleon (in J/nucleon) for Astatine-194: Here are some useful mass in amu: At-194 atomic mass = 193.999231    proton mass = 1.007276    neutron mass = 1.008665 Hydrogen-1 mass = 1.007825  

Use the standard reduction potentials to calculate at 25°C for the reaction,

A wooden artifact is found to have a carbon-14 activity of 8.2 disintegrations per second.  Given that the carbon-14 activity of an equal mass of freshly cut wood is 15.2 disintegrations per second, determine the age of the artifact in years.  The half-life of carbon-14 is 5717 years.
