  • Cool Reaction the Endothermic Reaction Between SCIENTIFIC Barium Hydroxide and Ammonium Thiocyanate
    Cool Reaction The Endothermic Reaction Between SCIENTIFIC Barium Hydroxide and Ammonium Thiocyanate Introduction Many reactions produce heat, in fact when people think of chemical reactions, heat production is often expected. However, endothermic reactions, reactions which consume heat, can be just as exciting. One of the most striking examples of this is when the solids barium hydroxide and ammonium thiocyanate are mixed together in a beaker. Materials Ammonium thiocyanate, NH4SCN, 10 g Stirring rod Barium hydroxide octahydrate, Ba(OH)28H2O, 20 g Thermometer graduated to at least –30 °C Erlenmeyer flask, small, with stopper, or a 50-mL beaker Safety Precautions Barium salts are toxic by ingestion. Ammonium thiocyanate is also toxic by ingestion. Use caution when handling the beaker or flask. Use tongs if available. The temperatures involved are cold enough to freeze skin. Ammonia vapor is very irritating to eyes and the respiratory tract. Do not allow students to inhale this gas. Wear chemical splash goggles, chemical-resistant gloves, and a chemical-resistant apron. Please review current Material Safety Data Sheets for additional safety, handling, and disposal information. Procedure 1. Transfer 20 g of barium hydroxide and 10 g of ammonium thiocyanate to a flask and mix with a glass or plastic stirring rod. 2. In less than two minutes the solids become liquid. A thermometer placed in the mixture shows the temperature falling far below freezing. An ammonia odor is evident to all who are near the flask. 3. Place the flask in a small puddle of water and your students will clearly see just how cool this reaction is; the water will freeze the flask to the counter top.

  • Writing Total and Net Ionic Equations
    WRITING TOTAL AND NET IONIC EQUATIONS http://www.csun.edu/~hcchm001/FreshChemHandouts.html 1. Write the overall equation including the correct designations for the physical state of the substances (s, l, g, aq). Balance this equation. Most of these kinds of equations are double displacement reactions: AX + BY 6 AY + BX 2. For the total ionic equations, write strong electrolytes in solution in the form of aqueous ions. (a) Strong acids. The common strong acids and their aqueous ions are: HI Hydroiodic acid H+-(aq) + I (aq) HBr Hydrobromic acid H+-(aq) + Br (aq) HCl Hydrochloric acid H+-(aq) + Cl (aq) +- HNO33Nitric acid H (aq) + NO (aq) +- HClO44Perchloric acid H (aq) + ClO (aq) +-2 H24SO Sulfuric acid 2 H (aq) + SO4(aq) (b) Strong bases. Strong bases are the hydroxides of the alkali (Group IA) and alkaline earth (Group IIA) metals ions which are sufficiently soluble. The common strong bases and their aqueous ions are: LiOH Lithium hydroxide Li+-(aq) + OH (aq) NaOH Sodium hydroxide Na+-(aq) + OH (aq) KOH Potassium hydroxide K+-(aq) + OH (aq) +2 - Sr(OH)2Strontium hydroxide Sr (aq) + 2 OH (aq) +2 - Ba(OH)2 Barium hydroxide Ba (aq) + 2 OH (aq) (c) Soluble salts.

  • Aldehydes Can React with Alcohols to Form Hemiacetals
    340 14 . Nucleophilic substitution at C=O with loss of carbonyl oxygen You have, in fact, already met some reactions in which the carbonyl oxygen atom can be lost, but you probably didn’t notice at the time. The equilibrium between an aldehyde or ketone and its hydrate (p. 000) is one such reaction. O HO OH H2O + R1 R2 R1 R2 When the hydrate reverts to starting materials, either of its two oxygen atoms must leave: one OPh came from the water and one from the carbonyl group, so 50% of the time the oxygen atom that belonged to the carbonyl group will be lost. Usually, this is of no consequence, but it can be useful. O For example, in 1968 some chemists studying the reactions that take place inside mass spectrometers needed to label the carbonyl oxygen atom of this ketone with the isotope 18 O. 16 18 By stirring the ‘normal’ O compound with a large excess of isotopically labelled water, H 2 O, for a few hours in the presence of a drop of acid they were able to make the required labelled com- í In Chapter 13 we saw this way of pound.

The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced.

  • Chapter 3. the Concept of Protecting Functional Groups
    Chapter 3. The Concept of Protecting Functional Groups When a chemical reaction is to be carried out selectively at one reactive site in a multifunctional compound, other reactive sites must be temporarily blocked. A protecting group must fulfill a number of requirements: • The protecting group reagent must react selectively (kinetic chemoselectivity) in good yield to give a protected substrate that is stable to the projected reactions. • The protecting group must be selectively removed in good yield by readily available reagents. • The protecting group should not have additional functionality that might provide additional sites of reaction. 3.1 Protecting of NH groups Primary and secondary amines are prone to oxidation, and N-H bonds undergo metallation on exposure to organolithium and Grignard reagents. Moreover, the amino group possesses a lone pair electrons, which can be protonated or reacted with electrophiles. To render the lone pair electrons less reactive, the amine can be converted into an amide via acylation. N-Benzylamine Useful for exposure to organometallic reagents or metal hydrides Hydrogenolysis Benzylamines are not cleaved by Lewis acid Pearlman’s catalyst Amides Basicity of nitrogen is reduced, making them less susceptible to attack by electrophilic reagent The group is stable to pH 1-14, nucleophiles, organometallics (except organolithium reagents), catalytic hydrogenation, and oxidation. Cleaved by strong acid (6N HCl, HBr) or diisobutylaluminum hydride Carbamates Behave like a amides, hence no longer act as nucleophile Stable to oxidizing agents and aqueous bases but may react with reducing agents. Iodotrimethylsilane is often the reagent for removal of this protecting group Stable to both aqueous acid and base Benzoyloxycarbonyl group for peptide synthesis t-butoxycarbonyl group(Boc) is inert to hydrogenolysis and resistant to bases and nucleophilic reagent.

  • Lab #9: Respiration
    BIOL 442 – Plant Physiology Lab #9: Respiration Report due: 30 Nov 2019 Germinating seeds are not yet able to acquire the energy they need through photosynthesis, and so they depend largely upon respiration for their early development. Germination and establishment are very important parts of a plant's life cycle through which numerous individuals do not survive. Therefore, measuring respiration rate of this stage under different environmental conditions will supply us with a greater understanding of these critical developmental stages. In the first experiment of this exercise, we will measure the respiration rate of germinating seeds at four different temperatures comparing them to controls which do not contain seeds. In the second experiment, you will stain seeds that have been germinated at three different temperatures with a compound that will become colored in actively respiring cells. These results will be used to assess the effects of temperature on respiration for developing seedlings. Objectives: Measure the respiration rate of seeds at different temperatures of seeds (seeds were germinated at room temperature). Observe respiration activity (by color changes in a dye indicating respiratory enzyme activity) for seeds germinated at three different temperatures. Materials: 0.1 M Ba(OH)2 solution -- Be careful. As a strong base, it is TOXIC. 1 M HCl 1 % phenolphthalein cheesecloth string 1 % Tetrazolium Because of time constraints, each group of students will split into two sub-groups: one sub-group will perform Experiment 1, and one sub-group will perform Experiment 2, the tetrazolium experiment. If either sub-group of your group finishes before the others, they are expected to help with the other parts of these experiments.
