  • Interhalogen Synthesis Lab Report

    Introduction Interhalogen compounds are molecules containing two or more different halogen atoms. The general formula for interhalogen consists of XYn, where n is equal to 1,3,5 or 7 and the central halogen, X, being less electronegative than halogen Y results in the formation of polarized covalent bonds. This experiment consisted of using experimental techniques to synthesize and decompose highly reactive, thus unstable, interhalogens that seemingly violate the octet rule. Synthesis reaction: KClO3 + I2 + 6HCl → KCl + 2ICl3 + 3H2O Decomposition reaction: I2Cl6 → 2ICl + 2Cl2 The halogens used within this experiment consisted of Iodine and Chlorine to produce an oxidizing reagent Iodine trichloride. Due to electron orbitals and their interactions…

  • Emergency Headlights Research Paper

    able to be see during responses after dark, and would also far less visible to others during the daytime. Headlights come in a few different styles. The three compaired here will be Halogen, Xenon, and LED headlights. They will be compaired on their economics, effectiveness, and overall safety. Halogen bulbs are the most popular headlight in use today, mainly because they are cheap. Halogen is a term used to describe a group of five very dangerous chemicals. Every bulb has a thin piece of metal…

  • Experiment 5: Anions And Redox Reactions

    Experiment 5: Anions and Redox Reactions Introduction (a) Objectives General: To examine the importance of potassium permanganate as an oxidising agent and the strong powers of halogens in oxidation. Part 1 Determining the colour associated with a certain halogen by adding a sample of the halogen to cyclohexane and recording the colours observed. Part 2 Identifying a halogen referring to the colours recorded in part 1, by reacting the halogen with a halide and observing the colour present.…

  • Creative Chemistry: Saunders N. 2000: Creative Chemistry

    Ref: Saunders N. 2000, Creative Chemistry You have seen that the Group 1 alkali metal elements increase in reactivity as you go down the group. Sodium is less reactive than potassium, which is less reactive than rubidium (which you weren’t allowed to observe directly!) Today, you will use displacement reactions to work out the order of reactivity of the Group 17 halogen elements using chlorine, bromine and iodine. Hypothesis: The higher on the periodic table the more reactive the element…

  • The Reactions Of Halocoalkane's Reaction With Halogenalkane

    with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes can also be classified into three categories according to what is…

  • Differences And Similarities Between Dmitri Mendeleev And The Modern Periodic Table

    We use this method because when Mendeleev used atomic weight it made some of the elements skewed. For example, if you take the elements Te (Tellurium) and I (Iodine) they would not be in the correct order according to atomic weight, Te and I would need to be reversed. If they were reversed, then Iodine would not be in the same column as the other halogens. This is the reason we now arrange the elements of the periodic table according to increasing atomic…

  • Essay On The Periodic Table Of Elements

    These families, shown and labeled in figure 2, include alkali metals, alkaline earth metals, transition metals, non-metals, metalloids, halogen gases, noble gases, lanthanides (or rare earth metals), and actinides (or rare earth metals). The first family includes group 1 on the periodic table. These metals are extremely reactive as they have 1 electron in their outer orbits. Hydrogen is included in this group because it also has 1 electron in its outer orbit and shares the reactive traits of the…

  • How Did Demitri Mendeleeve Invented The Periodic Table

    One big difference in the two was the amount of elements included in the table. Mendeleeve’s had about 60 different elements and today’s periodic table has around 120 different elements. They were also organised differently. Mendeleeve’s was ordered by the atomic mass and today’s is ordered by the atomic number. The modern periodic table is organised into columns and rows by what type of element they are, Mendeleeve did not have any type of organisation or type of rows or columns. Today, the…

  • Spinach Thylakoid Membrane Permeability Lab Report

    for the designated DCMU tubes. For the NH4CL tubes, the final NH4CL concentration was 2.9 mM. The difference between the final and initial A600 for the triplicates of each effector was averaged. A column graph was constructed for the effectors and used the mean change in absorbance as the dependent variable. Results: A spectrophotometer was used to recorded the initial and final A600 for all tubed in the lab. It is important to note a higher mean change in absorbance is a signal that electron…
