Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate

2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical changes and two chemical changes. This was important in determining the substance

too timid and squeamish about your actions. All life is an experiment.’’ The preceding quote means that people only get one chance to live. They should not waste time second guessing their actions. If you want to do something reasonable then go for it and don’t hold back. I am able to relate to this quote in several ways. One example is when I go mountain biking. I tend to second guess myself about going over the jumps. Another example of relation to this quote is Abraham Lincoln. He made many very

Chemical Warfare Diyora Shukurova Period 1 06-05-2014 Chemical warfare is known as the “use of toxic chemicals in battle.” Chemicals have been used for battle throughout centuries. But also known as any toxic chemical which is deadly or can cause injuries. For example‚ poisoned arrows‚ boiling tar‚ arsenic smoke and noxious fumes‚ and there are many more. Chemical weapons were first used in 1915. The germen military was the first to release 168 tons of chlorine gas at Ypres and Belgium which caused

TRACE EVIDENCE AS AN IMPORTANT TOOL UNDER FORENSIC SCIENCE Introduction Edmond Locard‚ founder of the Institute of Criminalistics at the University of Lyon‚ France‚ developed what has become known as Locard’s Exchange Principle. This states that “every contact leaves a trace”‚ implying that a criminal will leave trace and take away trace evidence when at a crime scene. Trace evidence often refers to minute samples of a substance‚ particularly fibres‚ hairs‚ glass fragments and paint chips. Crime

Chemical Periodicity Gorospe‚ Jheremy Alden B. ____________________________________________________________________________________ ABSTRACT The experiment Chemical Periodicity was demonstrated by using different samples of Group IA‚ Group IIA and Group IVA elements. We placed each of the samples in each test tubes and the physical state‚ color‚ and appearance was identified. We determined the solubility of the elements by using distilled water. We used red and blue litmus paper for the Group

Evidence 1. “There is too much competition between students‚ which leads to increased pressure to do well. Cheating becomes a way to get the edge over the other students in the class. In addition‚ the penalties for getting caught are mild.” 2. “Today there is more pressure placed on students to do well. They are expected to receive good grades‚ play a sport‚ and volunteer if they are to be looked at by a good college. With a B tainting your transcript‚ a college might not look at you.”
