CHAPTER 9 ACID RAIN WHAT IS ACID RAIN Sulfur dioxide and nitrogen oxides are gases that occur naturally in the Earth s atmosphere These gases react with water oxygen and other chemicals in the atmosphere to form various acidic compounds including mild sulfuric acid and nitric nature the combination of rain and these oxides is part of a natural balance that nourishes plants and

June 5 2024 A Lola I think the question you are asking is how can you tell when a chemical reaction takes place This is not always easy because many reactions take place but do not show any visible signs of them happening However in the case of hydrochloric acid and calcium carbonate the reaction is easy to see because the calcium carbonate starts to fizz and release a gas carbon
