In this experiment‚ gravimetric analysis will be used to determine the unknown metal carbonate. Gravimetric analysis. Gravimetric analysis is a method where an ion being analyzed can be classified through their mass (Yoder 2018). Due to the fact that carbonates can be hygroscopic‚ which means it would be able to absorb water from water vapor‚ extra precautions have to be taken place to be able to get an accurate mass (Helmenstine 2017). This can be done by using a drying oven and a desiccator. A

Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength. Metal ions emitting

carry out the ideal form of civilization. In this paper‚ I argue Plato’s Allegory of the Cave justifies the need for a royal lie found in the Myth of the Metals‚ for the royal lie serves as an instrument towards achieving the ultimate polis. I examine this claim by describing and analyzing both the Allegory of the Cave and the Myth of the Metals‚ as well as depicting the philosopher’s challenges and the royals lie’s instrumental purpose. Plato’s Allegory of the Cave starts in a world where men are

I interviewed Ms.Pohan my english teacher‚ because she was fascinated by war movies and how different wars are depicted and was always fascinated by war movies. She said that her favorite movie based on the Vietnam war was Full Metal Jacket which she watched three times‚ once in highschool‚ once in college‚ and once in her twenties. She described the movie as unsettling with brutal honesty‚ saying that the movie does not tell you how to feel about what you are watching‚ creating

Factors Affecting the rate of Hydrogen Peroxide degradation using Catalase Introduction An enzyme is a globular protein which functions as a catalyst that speeds up the rate of a reaction without being consumed in the reaction. An enzyme-catalyzed reaction occurs when a substance called the substrate binds onto the active site of the enzyme. This joining allows for a reduction in the activation energy and the reduction in activation energy helps the reaction to occur at a quicker rate. Enzyme

Ironically it was Cimino who reminded Stone of nothing he experienced in Vietnam‚ and talked him into resurrecting “Platoon”. Stone portrays the war as more of a conflict between American soldiers internally rather than a conflict with the Vietcong. Platoon tells the story of Vietnam from the point of view of a naïve young soldier. The first thing he sees when arriving is rows of bodies being readied to be ship back to the United States. He finds out that other soldiers don’t associate with the

This buildup of waste in the waters not only affects the aquatic life but also mankind both directly and indirectly. Fish is considered as one of the main protein sources of food for humans. Water pollution leads to affecting fish with toxic metals resulting from different sources like accidental spillage of chemical
