A bit of Pokemon history to begin, Pokemon has been around for twenty years. Pokemon was created by Satoshi Tajiri and developed and released by Nintendo, Game Freak, and Creatures or better known as a trio joint company Pokemon Company or Pokemon Company International. Which was not official until 1998. The first sets of games were released in Japan on February 27, 1996, under the name Pocket Monsters Red and Green for the Nintendo Game Boy. While it has been here in the United States under…

substance that is not aqueous was formed. The reactions that did not form a precipitate were DNR, which means that they did not react. At station one barium chloride and potassium nitrate did not react but barium chloride and silver nitrate reacted to form barium nitrate and silver chloride. The precipitate at station one was silver chloride. Both reactions at station two did not react. Station three had a reaction occur between sodium carbonate and calcium sulfate forming sodium sulfate and…

known. Purpose: The purpose of this experiment is to determine the type of chemicals that are inside the mislabeled bottles. Materials: • pH strips • 8 bottles of known chemicals: o silver nitrate o iron (III) nitrate o copper (II) nitrate o sodium iodine o sodium hydroxide o nitric acid o lead (II) nitrate o sodium carbonate • 8 bottles of unlabeled chemicals the same contents as known chemicals • 1 well tray Procedure 1. Place 7-10 drops of each chemical (known and unknown) into…

“Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total…

make prints visible on porous surfaces, forensic scientists use one of three methods; Silver Nitrate, Ninhydrin and Iodine fuming. These three methods are known to be the most effective ways for developing prints. Silver Nitrate is best known for developing prints on porous surfaces. Specimen on these surfaces can either be sprayed by or immersed in a diluted form of Silver Nitrate. Three variants of silver nitrate solution are used, a 1% w/v aqueous solution, a 3% w/v aqueous solution, and a…

The role of sodium citrate is to reduce silver nitrate to silver (1). The role of D-glucose was to reduce silver nitrate into just silver, while soluble starch stabilizes the nanoparticles by surrounding them to prevent aggregation (1, 2, 3). The 1 M NaOH, 1 M HCl, and 1 M NaCl caused Batch A to aggregate. The nanoparticles aggregated with these reagents because these are all strong bases or strong acids, which dissociates completely and interacts with the oxidized citrate that separate the…
