If 2.0 moles of O2 is reacted with 2.0 moles of Strontium, which is the limiting reactant?

A) Sr C) SrO
B) O2 D) No reagent is limiting

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.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
