An electric current of 10.0 amperes is passed through a solution of gold(III) chloride for a period of 0.500 hours. After this period of time, how much gold has plated out on the cathode?
There are 96,500 coulombs/mol of electrons. A mol of gold has a mass of 197 g/mol. An
ampere is equal to 1 coulomb/second. It is necessary to transfer 3.00 mol electron/mol gold.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

there is none because earth is stationary and flat.
