Lithium

may not know about. Listed below are four different types of rechargeable batteries currently being used. In this section, I will cover: what each battery is, the products they are used by and their impact on the environment. 1. Lithium Ion • The first battery is the Lithium-ion battery, otherwise known as Li-ion. These batteries usually come as small dry-cell batteries,…

The aim of this experiment is to reduce chromium (III) to chromium (II) using Zinc as an oxidising reagent using Schlenk techniques in the inert gas atmosphere using Nitrogen. The goal is not to let oxidation happen that will prevent the formation of chromium (II) species. Also, the aim of this experiment is to successfully form chromium (II) acetate, to find its percentage yield and to conduct IR analysis to prove the success of the reaction as well as the purity of the compound. Magnetic…

Electric cars versus Gas powered cars Cars are an important part of the human life. It is used for everyday tasks such as commuting to work, school, and events. Humans love to find the fastest, most cost-effective ways to get a job done. Even though the job gets done faster doesn’t mean it 's the most ethical way being done. At the time of the Industrial Revolution is when advanced machinery and mechanics were introduced into society. Creating the need to have better transport for…

Besides this, iPhone 6S is also available in 128 GB model for the users who never want to run out of the storage. BATTERY LIFE Both the iPhones include the Built-in rechargeable lithium ion Battery. Both the iPhones have up to 14 hours of talk time. However, the iPhone SE is slightly more efficient at the internet use (3G - 12 hours and LTE, Wi-Fi - 13 hours) compared to the iPhone 6S (3G, LTE - 10 hours and Wi-Fi - 11 hours). Again…

In the Bay Back Battery Simulation, I was tasked to use strategic innovation to earn profits for the division of the consumer electronics manufacturer. As the President of Back Bay Battery, Inc., I was responsible for distributing funds for two types of batteries produced by the firm. Nickel Metal Hydride (NiMH) accounted for 80% of revenue for the firm while Ultracapacitor batteries (UC) only made up 20% revenue (Christensen & Shih, 2012). The company primary products covered portable power…

pure. The observed colours match those of the spectrum, and can be accepted as true. The observed colour for lithium was a dark red colour. Lithium’s emission spectrum consists of purple, blue, cyan and red. Few darker specks of blue were observed, possibly from the same substance that made the specks, when sodium was burned. The observed dark red colour fits the emission spectrum of lithium, and can therefore be accepted as true. Potassium burned a bright pink/purple colour, which fits the…

treatments currently in use, such as valproate and carbamazepine, and therapies, such as electroconvulsive therapy, for bipolar disorder, the most commonly used is lithium. Lithium has many side effects but has proven to be one of the most effective medications. However, there are some forms of bipolar disorder that cannot be treated with lithium and even manage to worsen…

One of the most famous example of the use of lithium hydroxide canisters to remove carbon dioxide was on the Apollo 13 mission. The chart below shows the percent composition of carbon dioxide and its effect on the human body. The chemisorption (a kind of absorption in which involves a chemical reaction between a substance and the absorbate, substance that is absorbed) of CO2 is a two step reaction in which lithium hydroxide monohydrate (LiOH•H2O) is first formed by the exothermic…

Nearly most of camera lens is made of glass. Now some manufacturers adopt sapphire to make camera lens. Compared with glass, the biggest advantage of sapphire is its hardness. It's nearly twice as hard as standard glass, and nearly as hard as diamond. The extremely high hardness means it is nearly impossible to scratch it. Sapphire also have a compressive strength of 2,000MP, about ten times that of stainless steel, which means it is extremely strong. Those attributes can guarantee the optics of…

very good results, which is why I will be going up in intervals of 1g for the experiment. I have also decided to use 40ml of water because it doesn’t affect the temperature change too much. After testing a range of different salts, I decided to use lithium chloride as it gave a good range of results. Finally, I chose to use a polystyrene cup to hold the solution because it was an insulator and kept the heat…
