A Ray of Hope Much like the dystopian and corrupt Republic in Marie Lu’s Legend, the world seems to be a sea of violence, destruction, death, and overall chaos. However, there is a way for some to survive. The American government has created vaults, or well fortified buildings, that can guarantee the safety of those inside during these hard and cruel times in the world, meaning that there is hope for some of the civilians to survive. Unfortunately, there is a keyword there and it is “some.”…

Since early human societies we have been using technology to advance and improve our lives this technology has evolved and changed with us as our societies changed. On such technology is the bow and arrow. The bow and arrow is an ancient technology which originated around the same time that the first human societies were forming. The use of the bow and arrow originated as a hunting tool in many different parts of the world. “The weapon was developed by many pre-civilized people across the world;…

passion. Through my passion for archery and bowhunting, I would make a business where I could design and manufacture compound bows for both tournament use and hunting. I believe that this business would be a good idea because bow companies and manufacturers today, concentrate too much on how the bow looks, rather than functionality, power, and technological innovation of a compound bow in this day and age could be. To better…

Identifying an Unknown Compound Using Various Chemical Analysis Techniques Joshua Nash and Aquilla Young Abstract The introduction of this lab report exposes the reader to the different scientific concepts that are to be used such as melting point calculations, retention factors, and solubility in various aqueous solutions. The experimental provides the basics of using a melting point apparatus, determining solubility, and performing thin layer chromatography. In the results section the findings…

the lab was to identify an unlabeled compound found in the chemistry stockroom to be able to dispose of it properly. This lab demonstrated the process of identifying an unknown compound as well as synthesizing the compound. Identifying the compound consisted of performing various tests to detect the chemical and physical properties of the compound and comparing it to the list of possible compounds. The tests conducted were the solubility test which the compound fully dissolved in water, the…

Vinegar Dilute and Impure Acetic Acid or better known as vinegar is a compound formed by the chemical reaction of carbon, hydrogen and oxygen. The composition of vinegar is acetic acid (C2H4O2) and water. Also, the formula for this compound is CH3COOH. These elements are nonmetals,so the type of bond that this substance made is covalent. Vinegar has many kind of properties and utilization in several ways. For example, it can be use for food preparation, cleaning and health. When added in…

Introduction In this experiment, the goal was to isolate an organic substance. Using extraction, a basic, acidic, and neutral substance was expected to be extracted from the original unknown compound. Extraction is a process that allows the separation of substances that were previously mixed together through the use of a solvent1. This can be useful in situations where the substance has both the desired product and undesired byproducts in it. In order for extraction to work, the solvent must…

To carry out the experiment we need to get caffeine into a solution. We used a solid-liquid extraction by adding 14 tea bags into a 1L beaker with 6g of sodium carbonate, 250 mL of tap water and bringing this to a boil for five minutes on a hot plate. Sodium carbonate is a weak bronsted base, that neutralizes tannic acids extracted from tea, that interfere with the later sublimation operation.(1) We turned the heat off after five minutes, added ice cubes to cool the mixture to room temperature…

and 0.3 grams of sodium carbonate was added in. Sodium carbonate prevents caffeine from…

specific characteristics regarding solubility such that it dissolves the substance desired to be extracted while not dissolving or dissolving in only small portions the other substance not wanted purified out. It should also be easy to separate from the compound left in it after purification of the other so that complete purification can take take place4. This is why diethyl ether was used because it is a hydrocarbon, meaning it is mostly insoluble in water and satisfies the requirements…
