Electro-Alkaline Company. In 1928 the company hit the San Francisco stock exchange and formally changed their name to the Clorox Chemical Company. The company survived through the great depression however sales plummeted during WWII due a shortage of chlorine gas. Since the late 1970s the Clorox Chemical Company has expanded and now distributes its bleach products to over 100

Tangsiyuan Hua Mohammad Hasani Thursday-11:30-2:2 Synthesis of Triphenylmethanol from Benzophenone and Bromobenzene Abstract： The purpose of this experiment was to synthesize Triphenylmethanol by first producing the grignard reagent phenylmagnesium bromide. Then use the produced grignard reagent to synthesize triphenylmethanol, by reacting with benzophenone and then was protonated by H3O+. Recrystallization was used to purify the triphenylmethanol. The melting point was 161.7oC~162.5oc And
the air along with a quire of shrilling cries of metal wheels on steel tracks attempt to stop a thousand ton bomb. The freight train engineer tries to stop but noticed the sabotaged track to late and the train derails. A cloud of mix gas made up of chlorine, ammonia, and other gases begin to fill the air while fire starts to burn hundreds of tons of crude oil, heating the unbreached pressurized cars and turning each one into a time bomb. While this is a hypothetical scenario, everyday across the US
I: Purpose In this lab, our purpose was to observe the colors that were released by various metal ions. We wanted to be able to tell which element was which based off of the color of their flame. We also wanted to look at flame testing as a method of detection of metals. II: Procedure Acquire small samples of salts in marked test tubes. For each sample, add an amount of salt the fills the very tip of a scoopula. Pour roughly 15 mL of 6M HCI into a 50-mL beaker. Clean the wire loop by dipping
Introduction: This experiment is aimed to determine which ingredient within different types of coke produces the largest reaction with Mentos. The basic ingredients of Mentos and Coke are the main contributors to the explosive result. Mentos contains gum Arabic and gelatine while Coke contains caffeine, potassium benzoate and aspartame. The rough surface of Mentos provides growth sites for the carbon dioxide which will then lead to the breaking up of the strong polar attraction among the water molecules
Rate of Reaction Introduction: The Rate of Reaction defines the speed of the reaction that has taken place, determining whether it was fast or slow. For this experiment, I have decided to calculate the rate of reaction of the following equation: Hydrochloric Acid + Magnesium → Magnesium Chloride + Hydrogen 2HCl(aq) + Mg(s) → MgCl2(aq) + H2(g) In order to increase the rate of reaction, these following factors needs to be put in mind: The Temperature The Concentration The Mass of a substance The
Enzymatic browning in apple Renske Hinderks Food chemistry KLI011 Group C Introduction Many fruits and vegetables contain polyphenol oxidases (PPOs), which are a group copper-proteins. PPO is located in the plastids of plant cells, whilst the phenolic compounds are located in the vacuoles. When the tissue is damaged by cutting the fruit, both the plastids and vacuoles are broken, so that PPO can come into contact with the phenolic compounds. When the cut or damaged surfaces of these fruits and vegetables
eyes to the possibility of insecure chemical weapons and stockpiles concerns (Shea, Report, 2013). This statement shows the reality of how possible chemical warfare is still today in this day and time. During World War 1, when the Germans released chlorine gas and then later in the same war used mustard gas against their allies, was the first documented use of poison gases (Encyclopedia, 2013, pg1). These uses of toxic substances go back several thousand years with hunting methods such as; poisoned
There were many poisonous gases that played a role in World War I including the tear gas, chlorine, and mustard gas. The first chemical weapon in history was used by the French in 1914 against German forces. This poisonous gas is known as the tear gas. The fruity smell of this colorless gas was pleasant and drew soldiers curious. Some common symptoms of this gas were the irritation of eyes, mouth, throat, and lungs. Though this gas was not used to kill soldiers, it did not allow the enemy to defend
