Thermal Runaway Reactions Plan Hypothesis: In this experiment‚ my hypothesis is that‚ the more concentrated acid there is‚ the bigger the temperature change in the experiment. This is because there are more acid particles to collide & react with each other. Equipment: * Beaker (100cm3) * Assorted measuring cylinders * Stopwatch * Thermometer * 0.1g of magnesium powder * 10cm3 of sulphuric acid Method: First‚ I will measure the correct amount of magnesium I need‚

Definition of Terms American cockroach- the American cockroach (Periplaneta Americana)‚ also known as the waterbug or misidentified as the palmetto bug is the largest species of common cockroach‚ and often considered as pest. Breed- to produce offspring by hatching or gestation. Chitin- is a long chain polymer of N-acetylglucosamine‚ a derivative of glucose‚ and is found in many places throughout the natural world. Laboratory- is a facility that provides controlled conditions in which

the Earth. But today trees are in serious danger. Everybody knows that trees produce oxygen that we breathe and take carbon dioxide that we exhale that is why trees called the lungs of our world. As man cannot live without lungs‚ so and world cannot exist without trees. Factories‚ power stations and cars emit tons of smoke into the air. This smoke contains sulphur dioxide and nitrogen oxide. These substances mix with water vapor in the atmosphere and form sulphuric acid and nitric acid. Sunlight

Fusarium wilt caused by Fusarium oxysporum f.sp. ciceris is a soil and seed borne disease affecting chickpea whichis widely distributed where chickpea is grown. It causes yield losses in the range of 12 to 100 % depending on the level of resistance of the genotype and suitability of environmental conditions for disease development. Management of soil borne diseases mainly involves use of preventive measures because it is harder to control the disease once established. Thiram and carbendazim are used

What causes ASS? ASS are any material or sediment that contains iron sulfides that‚ when disturbed or drained‚ forms sulfuric acid. In most cases‚ the iron sulfide present is pyrite (FeS2‚ also known as Iron (IV) Sulfide). This pyrite is very reactive. It is usually the smaller crystals of pyrite found in ASS. The pyrite reacts with oxygen to create sulphuric acid (therefore disturbing the soil creates the acid‚ as the pyrite is exposed to the air). The smaller pyrite framboids (raspberry shaped

Sulfuric Acid is one of the the important chemical compounds. A Great amount of sulfur is mined all around the world and is used to produce sulfuric acid. Sulfuric acids being produced Sulfuric acid may seem like something to find in a lab‚ perhaps under the label “corrosive‚” and in some kind of tube that isn’t affected by it. But‚ in reality‚ it’s quite common‚ and is used often in the industrial business‚ for many different objects. Because of this‚ many places can often be judged upon their

Chapter I Part I. Research Study The Problem: Rationale and Background Paints are used to color‚ add protection and give texture to different kinds of objects around us. Paints have different components. Additives are pigments that give distinct effects on paints and special effects on the wall‚ woods and other materials. Coleus aromaticusbenth (oregano) is an herbal plant that can grow in any kind of soil. Some researchers from the University of Tennessee said that this

Introduction: Acid rain has proven to be a big problem for Connecticut. It has had a great impact on builders‚ wildlife‚ and the water sources. Acid rain has many components in it such as pollutants from plants to sulfuric acid from burning coal. Problem: Which stone is the most resistant against acid rain? Hypothesis: If we test the different stones against acid rain then red sand stone would be the best because it is heavier and cannot be easily broken. Independent variable: Type of stones

Introduction : Copper(II) sulphate‚ is a type of salt which it is formed by combining both copper ion and sulphate ion through the experiment of double displacement between dilute sulphuric acid ‚ and copper(II) carbonate ‚ . Through this process‚ the copper ion will displace the hydrogen ion as it is more electropositive and sulphate ion will displace carbonate ion as it is more electronegative. The resulting copper (II) sulphate solution when cooled can easily crystalize
