When heated above 200°C, sodium bicarbonate decomposes quickly to form sodium
carbonate, water, and carbon dioxide. Find the AH for the reaction, and classify the reaction
as endothermic or exothermic.
2NaHCO3(s) → Na, CO3(s) + H20(1) + CO2(9)
21-948 kJ/mol) → (-1311 kJ/mol) + (-286 kJ/mol) + (-394 kJ/mol)
AH = {AH, (products) - EAH, (reactants)

How is electrolysis most commonly used to produce an energy source? a - splitting water molecules produces oxygen, which organisms breathe to fuel their bodies. b - splitting water molecules produces hydrogen gas, which is used to power machines through hydrogen fuel cells. c - splitting carbon dioxide molecules produces coal, a form of carbon that can be burned to produce heat. d - splitting carbon dioxide molecules produces natural gas, which can be burned to generate electricity in power plants.
