Ashley Huston ILab‚ Week #2 CATIONS AND ANION LAB Introduction The purpose of this lab is to demonstrate a double-replacement reaction of ionic compounds. In this experiment‚ you will combine two ionic compounds. Both compounds are soluble in water. If a response happens between these two compounds‚ then a precipitate will form because one of the two resultant compounds is not soluble in water. This is a hint that a reaction took place. Cations are positively charged ions that are attracted

Lab Report Background Information: Magnesium is an alkaline earth metal that has the symbol Mg. Magnesium is a fairly strong‚ silvery-white‚ light-weight metal (one third lighter than aluminum). In a powder‚ it heats and ignites when exposed to moisture and burns with a white flame that is harmful to the eyes. It is difficult to ignite in bulk‚ but once ignited‚ it is difficult to extinguish. Magnesium Ribbon is a long strip of magnesium metal about 3 millimeters wide and 10 meters long with

Scientists speculated that organisms change over time. The British naturalist Charles Darwin made the most important contribution to scientific knowledge in 1859 on how organisms change or evolve over time. Darwin explained that the environment selects the kinds of adaptations in organisms that will help them to survive. (Charles Darwin) Scientist believed that this change affected a group of organisms called species. Theories of Evolution Darwin was not the first to propose a theory explaining

Materials: To complete all steps and smoothly complete the lab we first needed an almond‚ which what will be burned to find the energy and calories. Next we needed a paper clip to straighten out and put the almond on as a safe and efficient way to burn the almond. A scale and small aluminum-weighing dish were needed as well to weigh out the almond and paperclip. The lab also required a graduated cylinder‚ test tube‚ distilled water‚ thermometer‚ a Bunsen burner‚ a sparker‚ a calorimeter and safety

MACROMOLECULS LAB: What are the mystery powders? Period: 4 Asia Enoch Introduction: A carbohydrate is an immediate form of energy in your body. Monomers is smaller than a polymer. For carbohydrate the monomer is sugar and the polymer is a polysaccharides. Carbohydrates are important to our body because we need to use energy. The purpose of this lab is to figure which one is the monomer and which one is the polymer. Hypothesis: If I place two drops of iodine into the mystery powder‚ it
