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.
A 2.56 g sample of anthracene C14H10, was burned to heat an aluminum calorimeter (mass=948g). Explain the calorimeter contained 1.50 L of water with an initial temperature of 20.5 C as well as a final temperature of 34.3'C
