    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

    Acid rain is a very big pollution problem in the world. It has killed fish and other aquatic life in many lakes and streams. It harms human health‚ disfigures monuments and erodes buildings‚ and‚ along with other pollutants‚ threatens forests. The story of acid rain can be compared to the plot of a science fiction movie. In the 1950s an invisible force begins to destroy lakes and rivers‚ killing trout and salmon. By the 1960s it is harming the waters of eastern Canada and the northeastern United

    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

    1. Omega 3 fatty acids and Alzheimer’s disease Omega 3 fatty acids and Alzheimer’s disease how do they relate to one another? I have found in my research that omega 3 has been proven to show a delay in the process of Alzheimer’s disease and also has many other health benefits. This is my findings in doing my research. Although no one knows what causes Alzheimer ’s disease‚ many research studies indicate that those who regularly eat fatty fish or who supplement with fish oil have a lower

    Title: Measuring the loss in mass of Marble chips and Hydrochloric acid Aim: We will measure the loss in mass of the marble chips (CaCO 3 ) as it reacts with Hydrochloric acid (HCl). This one method of measuring the rate of reaction. We will use a balance to measure this mass loss as the reactants are used up to form product. Safety: * As Hydrochloric acid is corrosive wear a lab coat‚ gloves and safety goggles. * Take care when using the glassware not to cut yourself. * When

    Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will
