Electrochemistry: Lithium or Hydrogen? Unit 5: Electrochemistry SCH4U Yasmin Hashi May 14, 2018 Exploring Issues in Electrochemistry: Lithium or Hydrogen? Gasoline powered vehicles outnumber the amount of cars that are alternative powered. The combustion of fossil fuels like gasoline is considered a major source of air pollution and a contributor of climate change. Gasoline is an extremely flammable and very toxic liquid. This causes automotive experts to think that gasoline-powered vehicles will go extinct

The problem is that the world is a very massive place, where we need a lot of energy to fulfil the basic needs of our lives. Through the years we have been presented with several different alternative energy source options, as the energy sources like fossil fuels works against the environment. Nuclear fission is one of the alternative energy sources which is considered to be the future energy source of the world, but just like any other things nuclear fission has several disadvantages and advantages

Styrene Styrene is a toxic chemical that goes by many names such as ; Vinylbenzene , Ethenylbenzene , Phenyl Ethylene, Benzene and etc. Styrene is a colorless liquid that has an unsaturated ring that contains alternating double and single bonds ( Aromatic odor ).*This is an example of an aromatic compound known as Benzene, as shown above the unsaturated ring contains alternating double and single bonds. Styrene is a very important component that is used in making everyday products that you and I

solution transitioned into blue acidic solution. By referring to the solubility chart, SO4 (soluble), and water is the output. Last, a single displacement reaction transpired with zinc additional alongside to the previous solution to generate heat (Hydrogen gas materialises) and solid copper. Though, in the activity series, zinc is above copper, which means that zinc (II) sulphate is made then it begins to decay into another chemical equation. Additionally, it can be stated that, the group

magnesium and oxygen react together because when they are together heat is formed. This is why magnesium is used in items such as fireworks, flares and missile fuels in the form of powder. When magnesium reacts with acids it gives magnesium cloride+ hydrogen gas Magnesium+hydrocloric acid→ magnesium

1. INTRODUCTION Coal gasification is a process for producing a mixture gas consisting mainly of methane (CH4), carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapor (H2O) -from coal and water, air and / or oxygen. This gas mixture is called synthesis gas. Earlier, coal was gasified using old technology to produce coal gas (also known as the "town gas"), which is a fuel gas used previously for municipal lighting and heating before the advent of the commercial scale production

messengers or gasotransmitters. Gasotransmitters are a class above the receptor based signaling molecules as they are easily permeable across membranes and directly modify their intracellular targets.1,2 Nitric oxide (NO), Carbon monoxide (CO) and Hydrogen sulfide (H2S) are the enzymatically produced gases with biological functions to maintain the cellular homeostasis.3 Nitric oxide was the first discovered gaseous messenger for its regulatory activity in the nervous system and further research led

The innovation of the car has brought more positive and negative impacts than whatever other creation all through transportation history. As the most broadly acknowledged strategy for transportation, autos have changed the way individuals experience everywhere throughout the world. They have influenced all parts of society, for example, family life, the economy, and even nature. It is hard to find a film, book, or TV demonstrate that does not have some kind of car in it. this essay will demonstrate

In organic and inorganic chemistry, nucleophilic substitution reactions are the most well studied and useful class of reactions. These reactions can occur by a range of mechanisms, the two studied in this lab are the SN1 and SN2 reactions. In a nucleophilic substitution, the nucleophile is a electron rich chemical species which attacks the positive charge of an atom to replace a leaving group. Since nucleophiles donate electrons, they are defined as Lewis bases. The positive or partially positive

ABSTRACT The Diels-Alder reaction has been an area of great research interest with regards to enhancing enantioselectivity in the reaction by use of various catalysts and reaction conditions. INTRODUCTION In organic chemistry, a Diels-Alder reaction refers to a 4, 2 cycloaddition between a diene consisting of alternating double bonds and a substituted alkene (the dienophile) resulting in a substituted cyclohexene system. The reaction is often used to reliably control regioselective and enantioselective

Mariel Beauroyre 9-B A chemical bond is form with the joining of two or more atoms (when two atoms are joined they form molecules and compounds.) Which are being held together by the attraction (force attraction) of atoms through sharing as well as exchanging electrons. Chemical bonds are found in molecules, crystals, or in solid metals. They also organized the atoms in order structures. But why are they important you may ask? They’re important because every material or substance in the world

3.2.4 The catalyst concentration on epoxidation of cyclooctene using the investigated VO-complexes The effect of the catalyst was discovered by insertion of different molar ratios of the complex catalysts (L1VO, L2VO, L3VO and L4VO) to cyclooctene in the oxidation process (0.02, 0.05 and 0.10 : 1, respectively) using aqueous H2O2 in acetonitrile at 90 °C for 2 h (the optimized reaction conditions). In another words, the effect of the amounts of the catalysts related to the amount of the substrate

“Gunpowder” Introduction: Gunpowder, also referred to as Black Powder, is used as a chemical explosive. It is in use since early times. It is made up of three different materials, sulphur, charcoal and potassium nitrate (saltpeter). Charcoal and sulphur, both serve as fuels, and potassium nitrate is used as an oxidizer in it. Because of its burning capabilities and the amount of gas and heat that it produces, gunpowder has been utilized as a propellant in firearms mainly and in the pyrotechnic composition

Isatin The 1H-indole-2, 3-dione (Isatin), possesses an indole nucleus with two carbonyl groups; the keto and lactum group at positions C-2 and C-3. Isatin is an orange to red solid and is mostly used for synthesis of heterocyclic compounds [1]. The chemical structure of Isatin is shown in (Figure 1). Figure 1: Structure of 1H-indole-2, 3-dione (Isatin) In nature, isatin is present in plants of the genus Isatis, in Calanthe discolor lindl and in Couroupita guianensis

2.1 Chemistry of Bioluminescence Bioluminescence is the production of light as a result of a chemical reaction without the use of heat within a living organism. For bioluminescence to occur usually two substances and a by-product such as oxygen are required. In the majority of bioluminescent reactions, the chemical reaction which leads to bioluminescence is the oxidation of a molecule called luciferin. Luciferin, which is the substrate in this chemical reaction, is the chemical in the reaction which

alcohol with many commercial applications, presently finding its largest use in the pharmaceutical, food, cosmetic and chemical industries [2]. Glycerol also can be employed as the raw material to produce variety types of chemical products such as hydrogen, ethanol, propanol, acrolein, 1,3- propanediol, lactic acid, succnic acid, citric acid, polyesters

Chemistry Extended Essay “How does pH affect the concentration of trihalomethanes formed in a sample of reservoir water when it is disinfected with chlorine or chloramine and to what extent do both chloramine and free chlorine decompose when exposed to ultraviolet light?” Abstract This investigation aims to find out how pH affects the concentration of trihalomethanes formed in a sample of reservoir water when it is disinfected with chlorine or chloramine and the extent to which both

is the changes of substances or molecule from a solid state to a liquid state. Another words for melting are latent heat of fusion. When heat is transferred, the temperature will rise or fall typically. But there are also cases that heat does not change at all when heat is transferred. So this type of heat is called latent heat (Figura and Teixeira, 2007). So latent heat of fusion is also the enthalpy of fusion of a substances and molecule, or in another words is the changes of enthalpy of a substances

The dependent variable is the rate of decomposition of water which is measured by the volume of hydrogen gas and oxygen gas in cm3 The independent variable is the voltage here as I increase it from 9-14 Room temperature was 24 rtp and I carried out the whole experiment in the same room. If the temperature increases the rate of electrolysis will increase
