Experiment Hard Clam Juvinles term Toxicity: Introduction: Our testing involves exposing Hard clam juvinle to an interval of AgNo3 concentrations or a test sample for the purpose of determining the concentration or dilution levels that would cause the death of 50% of the organisms (LC50) exposed over 24 h and meeting the conditions defined by this method. If necessary and possible‚ the following may also be determined: a) the concentration level that causes the death of 20 % of organisms exposed

gelatin granules and distilled water to test if macromolecules could pass through a semipermeable membrane. The change of weight was observed. The last experiment used dialyzing bag filled with NaCl-methylene blue solution. As the Silver nitrate (AgNO3) was dropped‚ clouds were formed first‚ proving that salt reacted first than Methylene blue. As observed on the changes of the weight of the dialyzing bags and also on the reactions of plant and animal

This applies to each test. In the (Cl-) test‚ 2 drops silver nitrate(AgNo3) are added to each 2mL solution that has been measured and placed into a test tube from the obtained material from the cell. This test measures for the salt content in the solution. In the glucose test‚ Benedict’s test is performed using a 1:1 ratio

The Composition of Potassium Chlorate Objectives The objectives of this laboratory are: a) To experimentally determine the mass percent of oxygen in the compound potassium chlorate (KClO3) via the thermal decomposition of a sample of potassium chlorate. b) To qualitatively demonstrate that the residue resulting from the decomposition of potassium chlorate is potassium chloride. Background All compounds consist of elements chemically combined in fixed proportions – they obey the Law of Constant

The water from the creeks and water bodies around Brisbane will be unsafe to drink as the water is polluted and results will not be in the recommended requirements for safe drinking. It is expected that Bulimba Creek is polluted because it is a large water way and therefore it is hard for one committee to maintain the watery way’s health while respecting its biodiversity (BulimbaCreek.org‚ 2015). It is expected that Waterloo Bay is undrinkable because it is a salt water body (Health-e-waterways.org

Chemical Reactions Lab Objectives: 1. To examine a variety of reactions including precipitation‚ acid-base‚ gas forming‚ and oxidation-reduction reactions. 2. To identify the products formed in these reactions and summarize the chemical changes in terms of balanced chemical equations and net ionic equations. 3. To identify the species being oxidized and reduced in oxidation-reduction reactions and determine which species is the oxidizing agent and the reducing agent. Chemical equations represent
