<span>Ziggurats and pyramids greatly differ in terms of purpose or function. Pyramids were originally thought to be the final resting places of the pharaohs but more recent archaeological finds have uncovered that they were built with very narrow shafts extending from the inside to the outer surface for the purpose of lifting the pharaoh’s soul unto the heavens. Ziggurats on the other hand were said to have been built to house the gods. Thus, they are the actual dwelling places of the gods themselves especially in the point of view of the Sumerians and Babylonians.</span>
Answer:
The reaction is exothermic.
Explanation:
Enthalpy of Formation (ΔHrxn):
It is regarded as the variation in enthalpy when a mole of substance is produced at standard temperature and pressure through its pure elements under same conditions.
1) ΔHrxn = negative
When the energy is produced in the course of production of compound in a chemical reaction. It is known as Exothermic reaction.
2) ΔHrxn = posituve
When the energy taken in in the course of the production of compound in a chemical reaction. It is known as Endothermic reaction
The of production of carbon dioxide is negative. It implies that the ΔHrxn is an exothermic reaction.
