Inhalants are one of the most deadly categories of psychoactive substances available . Psychoactive substances cause mood and mind altering when used. Inhalant abuse is the intentional inhalation of solvents‚ aerosols‚ gasses and nitrites to achieve a quick‚ temporary euphoric/intoxicated state of mind known as a "high". The high is quick and temporary. The high only lasts a few minutes and is usually accompanied by distorted senses‚ dizziness‚ slurred speech‚ disorientation‚ loss of physical

components in a mixture‚ specifically sodium chloride and silica‚ and find the correlating percent composition of each. Abstract: This experiment consisted of the separation of sodium chloride and silica. The mixture was separated by extracting the sodium chloride with water and drying both substances. Adding water to the mixture‚ stirring‚ then decanting the resulting liquid twice extracts the dissolved sodium chloride from the silica. Heating both sodium chloride and silica separately provides the mass

Free Radical Bulk Polymerization of Styrene This protocol describes the bulk polymerization of styrene at 60 oC using 2‚2´azobisisobutyronitril (AIBN) as an initiator. The monomer styrene first has to be purified before it can be used. The purification is performed in order to remove inhibitors and impurities‚ which can

PHYSICAL PROPERTIES OF THE PERIOD 3 OXIDES These pages explain the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn’t form an oxide. A quick summary of the trends The oxides The oxides we’ll be looking at are: |Na2O |MgO |Al2O3 |SiO2 |P4O10 |SO3 |Cl2O7 | | | | | |P4O6 |SO2 |Cl2O

Lab 1: Flame Test 11 Chemistry‚ university Preparation Conducted: September 20th‚ 2010 Purpose: To observe‚ and create a chart of the colours produced when solutions of known metal compounds are heated to high temperature. Question: What colours are produced when different metallic compounds are placed in a flame‚ and why this happens? Hypothesis/Prediction: Different salts will produce different colours when placed in a flame‚ due to the fact that each element has a different

orange‚ coming in with the second lowest energy. Iron chloride had a “sparky” appearance that lasted for approximately six seconds and it was concluded that it had a high energy. Lithium chloride burned a pinkish color. Potassium chloride had a high energy and produced a purple flame. Strontium chloride had the lowest energy which was determined by red color of its flame. Unknown 1 was strontium chloride and unknown 2 was calcium chloride. The unknowns were found by comparing their flame colors

In this experiment an alloy of silver will be analyzed to determine its silver content. The silver-copper alloy will be dissolved in nitric acid‚ the silver will be precipitated as silver chloride‚ and the silver chloride will be filtered‚ washed‚ dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample‚ you will be able to calculate the percent of silver in the alloy. Because the results are based on the mass of a product‚ this procedure is classified

stabilizers were described by Bacaloglu [33]. The compositions of most lead-replacement stabilizers are proprietary because of unresolved patent and technical issues. They are reported to contain combinations of primary and secondary metals‚ metallic chloride deactivators‚ inorganic acid acceptors‚ metal coordinators‚ and antioxidants. Some of these use hydrotalcites similar to the well-known antacid Maalox®‚ which has aluminum‚ magnesium‚ hydroxyl‚ and carbonate functionalities. β-diketones‚ such as
