different types of negative effects acid rain has on the world. Acid rain is the mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Pollution contributes to the forming of acid rain. One of the main causes is industrial burning of coal and other fossil fuels the oxides they contain and combine with atmospheric water which forms acids. One of the effects of acid rain is the loss of fish in lakes and streams. These fish die because many

1) Natural buffers are chemicals that the body releases into the blood stream to help maintain a healthy pH level. Carbon dioxide (CO2) acts as an acid by donating hydrogen ions when needed and forms carbonic acid when it dissolves in water. Carbonic acid bicarbonate is important for maintaining an acid base balance in the blood as it equalizes the pH (7.5) of the blood. All body fluids have buffers that defend the body against pH changes. A process that affects buffers in the blood is exercise

7.4 Case Study: The Haber Process: Ammonia for Food and Bombs From: Eros Wang To: Ms. Irumekhai Date: March 30‚ 2012 1. Suggest five factors that could affect the production of ammonia in the Haber process. Explain the effect of each factor‚ using rate theory. The Haber process itself is a delicate balancing act because of all the factors that affect the yield of ammonia. In the Haber process‚ the nitrogen‚ hydrogen and ammonia are in equilibrium. So five factors that affect the

the last decade or so acid rain has caused destruction to hundreds of lakes and streams in many parts of the world‚ including the US‚ Canada‚ and Europe. Acid rain forms due to the oxides of sulfite and nitrogen combining with the moisture contained in the atmosphere‚ resulting in the formation of sulfuric and nitric acids. These acids can be dispersed far away from their places of origin. Acid rain seeps into the earth and poisons plants and trees by dissolving toxic substances in the soil‚ such

The three mineral acids commonly found in the laboratory are hydrochloric acid‚ sulphuric acid and nitric acid. 3. Alkalis taste bitter and feel soapy or slippery. 4. The common alkalis found in the laboratory are sodium hydroxide solution‚ potassium hydroxide solution‚ calcium hydroxide solution and ammonia solution. 10.2 Acid-Alkali Indicators

dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere to form sulfuric and nitric acids. The acids reach the ground and change the chemistry within the environment. The acidity of any solution is determined on the
