The diagram shows a series of volcanic islands and a hot spot. Determine the direction of movement of the tectonic plate that helped form the island’s.

So  if  the sum of the enthalpies of the reactants is greater than the products, the  reaction  will be  exothermic.  if  the products side has a larger enthalpy, the  reaction  is  endothermic. you may wonder why  endothermic reactions, which soak up energy or enthalpy from the environment, even happen

Your answer would be 625,000,000.
