Acid Rain Done By: Francis Lolas Teacher: Christine Due Date: 19/9/2012 Grade: 10 MYP 5 A There are many possible solutions to the problem that we are facing nowadays that is Acid Rain. Acid rain is formed from two main gases that are released in the atmosphere which are sulphur oxide and nitrogen oxide. I will talk later about the solutions for acid rain and the effect of this rain and what are the two forms of acid deposition. I have also watched some videos about acid

IODINE TEST FOR STARCH The Iodine test is used to test for the presence of starch. Iodine solution — iodine dissolved in an aqueous solution of potassium iodide — reacts with the starch producing a purple black color. The colour can be detected visually with concentrations of iodine as low as 0.00002M at 20°C. However the intensity of the colour decreases with increasing temperature and with the presence of water-miscible‚ organic solvents such as ethanol. Also the test cannot be done at very low

Animal Diversity The number of animal varieties familiar to us is vast as the animal world is diverse. Each distinct variety or type of animals is recognized by scientist as a species. Animals of most species are free-living forms but of others are parasitic in bodies of other animals or even plants.

Structural Isomers • molecules with the same molecular formula but with different arrangements of atoms • differences in the shape of isomers lead to differences in their physical & chemical properties • For example‚ galactose‚ glucose and fructose have the same molecular formula (C₆H₁₂O₆) but different structures (figure 6 page 30) • glucose itself has 3 different structural isomers in dry state‚ glucose has a linear structure‚ but when dissolved in water‚ the molecules fold on itself
