Science one world essay – Acid Rain Acid rain has been an important global issue for centuries. Although most acid rain is caused by human activities‚ some acid rain occurs naturally. An example of natural acid rain is erupting volcanos‚ they give off smoke containing water vapor‚ carbon dioxide‚ sulphur dioxide and nitrogen compounds. The sulphur dioxide and nitrogen compounds cause small amounts of acid rain near the volcano. Pure water is not an acid‚ but even clean rainwater is slightly acidic

ACID RAIN Cantarelli‚ Ilaria García Díaz‚ Bianca Gressier‚ Emilie Martínez Rivas‚ Carmen What’s the acid rain? Acid rain is a rain or any other form of precipitaton that is unusually acidic. What causes acid rain? Acid rain is caused by the burning of fossil fuels. Burning oil‚ gas and coal in power statons releases Sulphur Dioxide into the atmosphere. Burning oil and petrol in motor vehicles puts nitrogen oxides into the atmosphere. These gases mix with water droplets in the atmosphere creatng

Trans fatty acid is the process of adding hydrogen to vegetable oil this is really bad for your cholesterol. Hydrogenated fat is when hydrogen is added to liquid oil and it is turned in to a solid form like Crisco. Trans fatty acids are harmful to your cholesterol levels.

Acid Rain Within this past century‚ acidity of the air and acid rain have become recognized as one of the leading threats to our planet’s environment. No longer limited by geographic boundaries‚ acid causing emissions are causing problems all over the world. Some laws have been passed which limit the amount of pollutants that are released into the air‚ but tougher legislation must be implemented before this problem can be overcome. Acid rain is produced‚ when automobiles‚ smelters‚ power

Testing Food Substances for the Presence of Lipids Aim: To establish which food substances contain lipids. Hypothesis: 1. All diary products will contain lipids. 2. All animal tissue will contain lipids. 3. All plant storage organ products‚ i.e. seeds‚ will contain lipids. Introduction: Lipids are insoluble in water but soluble in organic solvents. Ethanol is an example of an organic polar solvent which will dissolve lipids to a limited extent. However ethanol is miscible with water so when

Investigating the effects of acid rain in the growth of cress seedlings IntroductionAcid rain is rain or any other form of precipitation‚ which is unusually acidic. It has harmful effects on plants‚ animals and buildings. Acid rain is mostly caused by human emissions of sulphur and nitrogen compounds which react in the atmosphere to produce acids. Acid rain can slow the growth of vulnerable forests and cause leaves and needles to turn brown and fall off. In addition‚ it depletes minerals from the

The intent of this paper is to educate individuals about acid rain‚ define its chemical makeup‚ and describe its impact on the environment. Rain is an important part of all life; it is the source of water for almost everything. In some areas rain is actually a threat to life because of pollution from cars‚ factories‚ and power plants. This pollution releases gases into the atmosphere to create acid rain. Acid rain is rain‚ or any other form of precipitation that is uncharacteristically acidic
