Dry-Ice Bubbling Acid What are the materials? Ammonia Ammonia (NH3) is a compound composed of one nitrogen (N) and three hydrogen (H) molecules. It is usually found as a gas and is known for its pungent odor. Ammonia is a gas. It is colorless, but has a very distinctive odor.
Limonene, the chief component of orange oil, is widely used as a fragrance and flavoring, as well as a cleaning solvent. Limonene, a naturally occurring hydrocarbon, is a cyclic monoterpene, a class of natural products biosynthesized by the assembly of isoprene units into various structures. Many terpenes are responsible for the odors of plants like eucalyptus, pine, mint, lavender, rose, and others. Organic chemists use terpenes and other natural products as chiral starting materials for complex chemical syntheses or as inspirations for pharmaceuticals. Some natural products are attractive synthetic targets because of interesting or unusual structural features or medicinal applications.
Caffeine Physical state: white to light yellow crystal powder | | Usage Cardiac and respiratory stimulant; diuretic | | General Description Odorless white powder or white glistening needles, usually melted together. Bitter taste. Solutions in water are neutral to litmus. Odorless.
It is quite like ethylene glycol. It has a boiling point of 188.2°C and a melting point of -59°C(7). What are the specific heat capacities of glycerol, water and olive oil? Glycerol: 2.5 J/g/°C (4) Water: 4.18 J/g/°C (2) Olive oil: 2.0 J/g/°C (3) How do the properties of these three liquids compare to the properties of the liquids used in radiators? Glycerol has some useful properties.
CHE 111 Laboratory 3 Hydrates Introduction Hydrates Water molecules combine with the molecules of certain substances, forming loose chemical combinations called hydrates. An example of a hydrate is MgSO4•7H2O. This formula means 7 water molecules are loosely attached to a magnesium sulfate molecule. Other examples of hydrates are Na2SO4•10H2O and Ba(OH)2•8H2O. When the hydrate is heated, it easily loses water molecules attached and becomes an anhydrous salt.
[pic] 10) The IR spectrum of m-xylene contains stretches which are characteristic of most aromatic hydrocarbons. List the peaks (in cm-1) associated with the aromatic C=C stretch and the aromatic C–H stretch. C-H just above 3000 cm-1, C=C ~ 1600 cm-1 11) How many distinct trichlorobenzene isomers are possible? 3 draw them! 12) When cyclohexene is treated with KMnO4, H2O, the syn-1,2-diol is produced.
Which are building blocks of life. Amino acids contain carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. Not only do organisms use twenty different amino acids to build protein which differ in number
Milk was extremely high in proteins, and lipids. It showed a negative result for peptides, and starches. Tomato juice tested moderately for peptides and high in lipids, and had negative results for proteins and starches. Ensure showed highly positive for proteins, moderately positive for starches and lipids, and showed a negative result for peptides. Gatorade showed negative results across the chart.
Chromatographic Analysis Ilagan, Mhariel Anne Denisse, Lacsamana, Marco Sebastian, Lanuza, Reggiana Mae, Latonio, Juan Paulo* Group 6, 2Bio5 Department of Biology, University of Santo Tomas, Manila, Philippines Abstract Chromatography is used to identify different components of certain samples and on plants, their different pigments. In this experiment, samples of common over-the-counter drugs and the sili were used as samples. They had different preparations. The analgesics were subjected to capillary-type of chromatography were the solvent travels up the TLC plate and the sili extract was subjected to column chromatography. The results for the Rf values of SX, Asp, Mef, Para, and Mef are 0.3538, 0.5538, 0.6462, 0.5077, and 0.6615, respectively.
The chemical is a colorless liquid which makes it nearly impossible to detect in water and has the ability to harm the population by inhaling the polluted air (OEHHA, 2000). Human exposure to this chemical has been reported to cause central nervous system (CNS) issues as well as hyperesthesia, and muscle spasms (OEHHA, 2000). 1,2,4-trichlorobenzene is a colorless man-made liquid with an unpleasant odor. 1,2,4-trichlorobenzene is also known as trichlorobenzene or TCB (DHSS, 2010). TCB is relatively similar to Chlorobenzene in regards of being an essential part in the production of dye.
