Introduction
The reaction of Hydro Chloric Acid with Aluminum is exothermic and very dynamic. The Hydrogen produced at such temperatures can easily explode by combining with the oxygen of the atmosphere. This reaction is known as a single displacement reaction because aluminum switches with the hydrogen. When aluminum is placed in a beaker of hydrochloric acid, the reaction produces hydrogen gas and aqueous aluminum chloride. The balanced chemical equation for the reaction is 2Al + 6HCl = 2AlCl3+ 3H2. The reaction produces two moles of aluminum chloride and three moles of hydrogen gas. The aluminum donates its valence electrons to become aluminum chloride
During this reaction Hydrogen Chloride gas evolves which is a highly corrosive and a poisonous substance more stable by connecting with chloride. The product Aluminum Chloride itself, is a solid substance that is very reactive. The reaction at the initial stages is slow and once the temperature picks up, it becomes very vigorous. The hydrogen is lighter, compared to air and hence diffuses to the atmosphere. Corrosion of steel and articles of iron is initiated by aluminum chloride.

Stoichiometry is typically used during reactions or formations to find quantities of the same unit. Chemical reactions are processes that rearrange the molecular structure of an element. A single-replacement reaction is a chemical reaction in which an element reacts with a compound and replaces a different element in another compound. Aluminum is one of the most abundant elements on Earth. It makes up about 7% of the Earth's crust. The oxide layer that aluminum forms makes the metal resistant to corrosion. Hydrochloric acid is a strong, corrosive acid. It is a colorless, highly strong solution of water containing hydrogen

    This lab makes use of the reaction excess powdered calcium carbonate and different concentrations limiting hydrochloric acid in order to determine the effect of changing concentration on the rate of the reaction. Students will carry out 3 trials of 5 experiments each trial. The five different experiments are for the various concentrations of hydrochloric acid (0.2, 0.4, 0.6, 0.8, 1.0 mol/L). First measure out approximately 2 grams of powdered calcium carbonate using a weighing boat and analytical balance. Then, measure out 30 mL of 0.2 M hydrochloric acid into a volumetric flask.…

    This lab is designed to find the mass of copper produced when excess aluminium is reacted with 2.00g of copper salt [Copper (II) chloride decahydrate]. This will be achieved by dissolving the given amount of copper salt in distilled water and then adding in the aluminium rod. The reaction will commence as copper will begin to form on the aluminium. Calculating the percent yield is commonly used in the atom economy of a chemical reaction, which is a measure of the initial substance which becomes the useful product(s). Reactions with low efficiency which generate a great amount of waste and produce a smaller amount of the product desired have low atom economies and therefore a lower percent yield.…

    These materials included, a clean dual petri dish, an iPhone 6s, two cotton balls, eight pill bugs, a small clear container, a small paint brush, a saturated pipet of 0.1M sodium hydroxide (NaOH), and a saturated pipet of 0.1M hydrochloric acid (HCl). Methods: After obtaining all the materials, the first thing done was to place the cotton balls in the center of each circle in the dual petri dish. The cotton ball on the left side of the dual petri dish was then saturated with 0.1M hydrochloric acid, and the cotton ball on the right side of the dual petri dish was saturated with 0.1M sodium hydroxide. Hydrochloric acid is labeled as a strong acid, which means it is high in acidity.…

    When hydrochloric acid was added to the unknown and known solutions, both resulted in no reaction. This also occurred when potassium hydroxide was added to both of the solutions. Barium chloride was then added to the two solutions, which resulted in a cloudy white precipitate from both of the solutions. A cloudy white precipitate also formed when calcium nitrate and ammonium nitrate were added to both the unknown and known solutions. These reactivity tests were conducted in order to establish how the unknown compound would react with acids, bases, and salts.…

    In this lab, we carried out a variety of reactions using different chemicals and metals. A chemical reaction is when the chemical state of the substance you are testing rearranges its ionic and molecular structure. One of the reactions we experienced was single replacement, this consists of one ion switching places with another ion to form a new compound. Another reaction we saw was double replacement. In this reaction, two compounds ions are switched to form two new compounds.…

    When exposed to water and air, the chemical element aluminum, does not corrode. However, the truth of the matter is that the shell of aluminum responds so promptly with water that its shell should dissolve in the rain. Despite this fact, when aluminum metal is set in an atmosphere, a thin layer, known as aluminum oxide, forms on the metal's surface, making it resistant to rust. At the point when the external layer of aluminum oxide gets hydrated or wet, its molecular structure alters only enough to become chemically inert, which is why it resists…

    The purpose of conducting this experiment was to explore how different factors affect the reaction rate of enzymes reacting with their corresponding substrates in order to learn more about how enzymes function in different environments. The independent variables investigated in this experiment were the concentration of different substrates, the temperature of the environment, and the effect of a catalyst on the reaction rate. The dependent variable for all of the investigations was the time it took for the reaction to occur. To investigate the effect of the concentration of the substrate on the reaction time, four test tubes were used.…
