Acid rain is rain that has become acidic‚ because of air pollutants in the atmosphere. Rain has a normal pH level of around 5-5.5 which is only slightly acidic. 7 on the pH scale is the neutral and anything below that is considered acidic. Acid rain has a pH level around 4 which is 10 times more acidic. Acid rain can fall in many different ways and has many effects on the environment. Acid rain is caused by air pollutants in the atmosphere. These air pollutants are mainly from man made resources

Hala Sughayar iLab: Week 1 BALANCE LAB Introduction The purpose of this week’s iLab is to find the weight of different objects and record my findings/data. I will record my data on a chart. My observations will determine why each scale has a different weight for the same object being weighed. The two techniques practiced here are direct weighing and weighing by difference. The skills required vary depending upon the kind of balance used. In this lab I will practice the techniques required

Acid Rain Webquest Name: ________Jacob Rough_________________________ Date: _____3/25/13________ Sulfur dioxide and nitrogen oxides are gases released by the burning of fossil fuels. These gases can react with water and oxygen to form acids. Normally‚ rainwater is slightly acidic. But the additional acid that enters the air when fuels are burned makes it even more acidic. Acid rain can have a harmful effect on fish and other wildlife and upsets the delicate balance

fuels‚ such as reserves of coal‚ oil and other fossil fuels are limited and non-renewable. In addition‚ the common practice of burning oil‚ coal‚ and other assorted hydrocarbons has resulted in hazardous environmental conditions such as global warming‚ acid rain and dangerously high air pollution levels. This and other environmental disasters have brought about a demand for alternative fuel and energy sources that are convenient‚ environmentally friendly‚ and economically viable.

Chemistry Research Task The Periodic Table of Elements The Periodic Table of Elements is used as a way of displaying all the known chemical elements; it is accepted and used all over the world. The periodic table’s layout is very well structured; it consists of vertical rows called groups and horizontal rows called periods. It is one of the most important resources in chemistry and the key to discovering new elements. The beauty of the Periodic Table is that a lot of information about any

structure of water Lewis structures (also known as Lewis dot diagrams‚ electron dot diagrams‚ and electron dot structures) are diagrams that show the bondingbetween atoms of a molecule and the lone pairs of electrons that may exist in the molecule.[1][2][3] A Lewis structure can be drawn for any covalently bondedmolecule‚ as well as coordination compounds. The Lewis structure was named after Gilbert Newton Lewis‚ who introduced it in his 1916 article The Atom and the Molecule.[4] They are similar
