Domoic acid

Problem: To discover what types of carbohydrates are in certain products Monosaccharides, disaccharides, or polysaccharide. Materials: The materials used are: Test tubes, Test tube holders, Glass marking pencil, benedict’s solution, Apple, Table sugar solution, I-KI solution, medicine dropper, hot plate, water, maple syrup solution, dextrose solution, envelope glue, monosaccharide solution, disaccharide solution, polysaccharide solution, and oats (cereal). Procedure: The procedure is: A. Known

composts are about to be in neutral pH within range from 6-8. However the initial pH of the manure compost will be more alkaline, with a pH as high as 8.5. Microorganism in compost will grow and multiply within the pH range from 5.5 to 8. The organic acids are formed in the initial stages of the aerobic decomposition process and these acidic conditions favor the growth of fungi

Sugar's effect on your health The average American consumes an astounding 2-3 pounds of sugar each week, which is not surprising considering that highly refined sugars in the forms of sucrose (table sugar), dextrose (corn sugar), and high-fructose corn syrup are being processed into so many foods such as bread, breakfast cereal, mayonnaise, peanut butter, ketchup, spaghetti sauce, and a plethora ofmicrowave meals. In the last 20 years, we have increased sugar consumption in the U.S. 26 pounds to

Will a bath bomb containing lime juice rather than citric acid dissolve faster? I think there is a chemical reaction within the bath bomb that makes it fizz, but I am not sure what things are reacting. I also think that if I substitute lime juice for citric acid in one half of the bath bomb, the half with citric acid will dissolve quicker. This is because it is pure citric acid, unlike lime juice which has other things as well as citric acid in it. Research Bath bombs are composed of several ingredients

whether cream of tartar, laundry detergent, and vinegar are neutral, bases, or acids. Introduction This experiment will discuss whether cream of tartar, laundry detergent, and vinegar are neutral, bases or acids contingent on changes in color. Neutral substances are chemicals that have no properties of either acids or bases, have equal parts hydrogen and hydronium ions and don't change the color of litmus paper or other acid-base indicators. A base is a chemical species that donates electrons or hydroxide

What is a ratio? A ratio is a way to compare and separate the values by dividing one value by the total. What is a chemical formula? A chemical formula is a way to show chemical symbols and numbers to represent a substance. Compare and contrast the properties of water with the properties of hydrogen and oxygen. Water, Hydrogen, and Oxygen have many similarities and differences. The similarities of the 3 are that they can be turned into a gas (gas state) by this water can turn into liquid by the

Another candidate is N2H4BH3 (hydrazine borane, HB) solid with 15.4 wt% hydrogen capacity, which can release 5.8 wt% H2 at 140 C in 12 min [4] and can yield 11 wt% H2 at 150 °C in less than an hour after mixing with LiH, has attracted more attention and has been experimentally studied as one novel B-N-based material for hydrogen storage through different routes, such as thermal decomposition, hydrolysis, etc… [5-9]. This material can be easily prepared from a reaction of dihydrazine sulfate with

What is Calcium? The chemical element Calcium (Ca) is a malleable, ductile, soft metal. It's located in period four and group two of the periodic table. Calcium atoms have 20 electrons and 20 protons, there are two valence electrons in the outer shells. Its mass number is approximately 40.08. Calcium has four stable isotopes including 40Ca, 42Ca, 43Ca, and 44Ca; 97% of naturally occurring calcium is in the isotope 40Ca. Isotopes are atoms that have the same number of protons and electrons, but

The raw atenolol and metoprolol powder were the kind gift from Swiss Pharmaceutical Co., Ltd, Taiwan. Chemically, atenolol (free base) and metoprolol have a molecular weight of 266 and 267 (Lennernasi, et al., 1994; Gros, et al., 2006b), the melting point between 152℃ and 156.5℃ (USP, 2005). It is a relatively polar hydrophilic compound with a water solubility of 13.3 mg/mL at 25℃(Gros, et al., 2006b). The extent of ATN molecule was estimated to be 7x18.2 Å (Lennernasi, et al., 1994, Sybyl®; Fagerholm

For the Benedict’s test I used tube clamps, a grease pencil,6 test tubes, a tube rack,6 unknown substances, and Benedict’s reagent. There was a hot plate and beaker of water already set up. I started by numbering the test tubes 1-5 with the grease pencil and left one for water as the control. I turned on the hotplate and prepared the beaker of water for the bath I would need later in the experiment and let it heat up. While that was boiling I added 5mL of unknown substance 1 to test tube 1 and continued
