An Experiment to find the Concentration of a Sample of Acid Rain Plan Aim When a metal is extracted from its ore often sulphur dioxide is produced. When sulphur dioxide is dissolved in water it forms a strong acid called sulphuric acid. Sulphuric acid is often sold as a useful by-product‚ but also gets into the water cycle and forms acid rain. In this experiment‚ I have been given a sample acid rain of concentration between 0.05 mol dm-3 and 0.15 mol dm-3 and my aim is to find out exactly what

The chemical equation of a Perkin Reaction can be seen below. The reaction mechanism for the synthesis of α-phenylcinnamic acid is shown below: Results: Theoretical Yield Therefore‚ phenylacetic acid is the limiting reagent. Table 1.

James Downing was part of the navy unit on pearl harbor. He was only 28 at the time and it was his 9th year in the navy. James remarked “I was doing my daily job‚ to find out that we were under attack.” James Downing was a gunner’s 1st mate and postmaster. He was eating breakfast with a couple other service men. His wife‚ Morena‚ was cooking the breakfast. They were fine until they heard a few explosions go off. “Then an anti-aircraft shell

A study by the FBI confirmed that most of these shooters don’t just one day “snap”. Elliot Rodger planned out his attack for a whole year before he committed it and he had a 137 page manifesto left behind for the world to see. This behavior isn’t his alone‚ it’s mirrored in other shooters. Most of these people know they are going to die‚ and so they plan out every part of it like a presentation. Their main goal isn’t the killings‚ but the message it sends and the aftermath displayed on TV. It’s calculated

hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen. The magnesium displaces the hydrogen in the acid‚ so it forms

Global Bio Succinic Acid Market published at Truemarketresearch.com The U.S. Department of Energy (USDOE) considers succinic acid as one among the top twelve chemical building blocks. Succinic acid‚ as a platform chemical‚ is growing in demand in various applications. However‚ consumption of petroleum based succinic acid‚ as an intermediate‚ in manufacturing various chemicals‚ is limited due to its volatility of price and carbon footprints. These concerns led to the discovery of biological manufacturing

Acid rain is any type of precipitation that has high acid content. This precipitation can be wet (rain‚ snow‚ or fog) or dry (gases or acidic salts). Normal rain is slightly acidic with pH 6.5 but we call it acid rain when it is pH is between 2 and 5.5. It is formed by chemicals created by the burning of fossil fuels‚ power plants‚ factories and auto mobiles. These chemicals are sulfur dioxide and nitric oxide. Sulphur dioxide and nitric oxide react with water in the atmosphere and eventually fall

Preparing Esters by esterification method using carboxylic acid to an alcohol‚ which is 1.0 ml of ethanoic acid to the ethanol‚ and ethanoic acid to the propan-1-ol‚ also adding H2SO4 as a catalyst for the reaction Abstract: Esters are a group of organic compound‚ famous for their interesting odours and smells. In this investigation student used ethanoic acid and ethanol with sulfuric acid as catalyst to produce ester‚ which was known of its smell. However it was expected to have a pleasant smell

acid rain Acid rain is rain or any other form of precipitation that is unusually acidic. It has harmful effects on plants‚ aquatic animals‚ and infrastructure. Acid rain is mostly caused by human emissions of sulfur and nitrogen compounds which react in the atmosphere to produce acids. In recent years‚ many governments have introduced laws to reduce these emissions. Emissions from volcanoes and those from biological processes that occur on the land‚ in wetlands‚ and in the oceans account for the
