If you combine 2 g H2 and 20 g 02 to make water which is your limiting reactant?
2H2 + O2- 2H20

the answer is either b or c

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.

c, liquids evaporate, creating a gas
