Experiment 7 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction: The student will perform the experiment in order to find the percent yield by using the theoretical value found using the balanced equation for sodium carbonate as well as sodium bicarbonate. The objective is to stabilize the substances by titrations and finding the percent yield when all the data is collected. The purpose of this procedure is so that the student will get better understanding of stoichiometry

How does acid precipitation affect marble and limestone buildings? Acid rain is a type of precipitation that is characterised by containing contaminating substances such as sulphuric and nitric acid‚ both of which have harmful effects on the environment. Both marble and limestone are extremely vulnerable to the damages done by acid rain due to their components. These materials contain calcite‚ a substance that easily reacts and dissolves with acid. Acid rain is the cause of the destruction of many

A Swiss chemist named Dr. Albert Hoffman first produced lysergic acid Diethylmide or best known as LSD in 1938 (Dye‚ 1992‚ p. 2). Hoffman discovered the drug while trying to synthesize a new drug for the treatment of headaches. He obtained the lysergic acid from the parasitic fungus that grows on rye plants known as ergot. From the lysergic acid‚ he synthesized the compound LSD. He used the compound to test for its pain killing properties on laboratory animals. Being that appeared totally ineffective

given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl)‚ Sulphuric acid (H2SO4) etc. An alkali is a soluble base and forms hydroxyl ions (OH-) when placed in water. It

In 1941‚ the attack on Pearl Harbor and the fall of Hong Kong led to the declaration of war between Canada and Japan. The sacrifice of 2‚000 Canadian soldiers in the invasion of Hong Kong raised fear and rage against Japanese on the west coast. Along with several government policies which provide room for the entrenched racism‚ rationality is dissolved into violence and repression which pressures the government for the final detention. Japan was allied with Britain in the First World War‚ thus the

The terrorist attack planned by Al Qaeda terrorists caused many psychological impacts in America. When the Airplanes had rashes into the significant twin towers‚ there were many people inside working. For many victims everything had occurred so fast. For Materson‚ he says “I went into shock” (Jost). “He cannot recall seeing anyone jump from the towers‚ but he learned what he came to realize were the sounds of the bodies hitting the pavement” (Jost). The aftermath of the attack was what really had

My design‚ like Pape (2003)‚ is going to look at suicide attacks but my area of focus is going to be from 1980-2015. This reason for the change is because I want to expand on the data collected by Pape (2003)‚ from the Lexis Nexis data base. Another area of change my research will have is on the properties collected from the data. As citied earlier Pape (2003) looked at three properties I’m only going to look at two. Pape’s main findings are supported by three general patterns he finds in an extensive
