Aluminum foil is heated and placed in a flask containing chlorine gas. The aluminum reacts vigorously with the chlorine to form a cloud of aluminum chloride.
Aluminum foil is heated...
...and placed in a flask containing chlorine gas.
The aluminum reacts vigorously with the chlorine...
Aluminum and chlorine do not react rapidly at room temperature, but if the aluminum is heated, the reaction is vigorous. The product is aluminum chloride, a white powder that fumes in air, reacting with water to form HCl gas and aluminum oxide.
1. What observable evidence indicates that a chemical reaction has taken place?
2. Classify the reaction shown in the video as combination, decomposition, exchange, acid-base, or redox. (The reaction may fall within more than one of these categories.)
3. Is the reaction shown exothermic or endothermic? Cite observations that justify your choice.
4. When the natural gas flame is lowered from air into the container of chlorine, the color of the flame changes. Explain why the color of the flame changes.Base your explanation on the theory of spectra of atoms and molecules.
The chemical formula of chlorine gas is Cl2. It is yellow-green in colour and has an odour which is similar to to the household bleach. It is soluble in water and reacts to form hypochlorous acid and hydrochloric acid.
Aluminum chloride is a chemical compound with the chemical formula AlCl3. When contaminated with iron chloride, it often displays a yellow color compared to the white pure compound. It is used in various chemical applications as a Lewis base, with anhydrous aluminium trichloride being the most commonly used Lewis acid.
Aluminum and chlorine do not react rapidly at room temperature, but if the aluminum is heated, the reaction is vigorous. The product is aluminum chloride, a white powder that fumes in air, reacting with water to form HCl gas and aluminum oxide.
Aluminium reacts with chlorine gas to form aluminium chloride via the following reaction: 2Al+3Cl2→2AlCl3. How many grams of aluminium chloride could be produced from 34 g of aluminium and 39 g of chlorine gas?
Aluminum chloride (AlCl3) is considered a covalent compound. While it contains both metal (aluminum, Al) and nonmetal (chlorine, Cl) elements, the bonding between the aluminum and chlorine atoms is primarily covalent in nature.
The chemical formula for aluminium chloride is AlCl3. This formula succinctly represents the composition of this inorganic compound. It consists of one aluminum (Al) atom and three chlorine (Cl) atoms bonded together.
Chlorine (Cl) can also bond with aluminum (Al). Aluminum has three extra electrons and will easily let the chlorine atoms use them. Because aluminum has three, that means three chlorine atoms can bond. They make the formula AlCl3, also known as aluminum trichloride.
The molecular formula AlCl3 tells us that the compound aluminum chloride contains the elements aluminum (Al) and chlorine (Cl). The formula also tells us that the ratio of aluminum atoms to chlorine atoms is 1:3. For every aluminum atom, there are 3 chlorine atoms.
Aluminium chloride is produced on a large scale through the 'exothermic reaction' of aluminium metal with hydrogen chloride or chlorine at temperatures ranging from '650° C to 750° C'. Aluminium chloride can be created by combining copper chloride with aluminium metal in a single displacement reaction.
Gallium expands when it freezes, one of the few substances to do so. A small amount of gallium will destroy anything made out of aluminum, including aluminum cans.
Aluminum Chloride is a yellowish or grayish-white, crystalline powder with a sharp odor. It is used as a chemical intermediate for Aluminum compounds, as a catalyst for cracking petroleum, in preserving wood, and in medications, disinfectants, cosmetics, photography and textiles.
An oxidation-reduction reaction, also known as a redox reaction, occurs when metallic aluminium reacts with hydrochloric acid. Both oxidation and reduction occur at the same time.
