y of formation of ________ is zero.

From a molecular viewpoint, where does the energy emitted inan exothermic chemical reaction come from? Why does thereaction mixture undergo an increase in temperature eventhough energy is emitted?

Question 22 Which statement best describes the First Law of Thermodynamics? O Change in internal energy of a system is path-independent O Energy is neither created nor destroyed, rather it is conserved Heat flows from an object at a higher temperature to an object at a lower temperature Mass is neither created nor destroyed, rather it is conserved

When the sign of an energy change is being determined, this would always be with respect to what?
