Sulfur dioxide and nitrogen dioxide form an acidic compound in the atmosphere when they react with the moisture (humidity) in the air. These are transported in by the prevailing winds from coal-fired power plants in Ohio and are often rained out in the mountains of New England (e.g., New Hampshire and Vermont).The rains form runoff that travel to streams and eventually to lakes where the higher forms of life are eradicated.
Question- If the enthalpies of formation of carbon dioxide and water are -393.509 kJ/mol and -285.83 kJ/mol respectively, what is the enthalpy of formation of C10H8(s) in kJ/mol
