Introduction The purpose of the experiment was to determine the melting points of compounds using a Mel-Temp device. The melting point of naphthalene‚ urea‚ and sulfanilamide are found. This is then followed by the measuring of an unknown compound‚ and an impure sample (a small amount of naphthalene mixed with the unknown). Experiment In the lab‚ the height of the chemical in the capillary was set to 2-3 mm thickness. The voltage at the Mel-Temp started at a low setting of 1.5-2. The heat was

The virus can also contaminate seed coats‚ and the plants germinating from these seeds can become infected. Once TMV enters the cell‚ the virus particles disassemble in an organized manner to expose the TMV RNA. The virus RNA is positive-sense‚ or "+ sense"‚ and serves directly as a messenger RNA (mRNA) that is translated

Melting Point Determination Lab Materials: Graduated pipette Capillary tube Tin wipe Sample Melting temperature apparatus Thermometer Procedure: Take open end of capillary tube and tap it gently into sample. Take tin wipe and place over the opening. Gently tab it so the sample will funnel to the bottom of the tube. You may also use a graduated pipette to accomplish this. Now‚ place the capillary tube in the designated spot in the melting apparatus‚ and once placed‚ turn the apparatus

REPORTIntroductionWater is a liquid that freezes and also melts at 32*F (0*C). Melting and freezing points are temperatures when a solid substance turns to a liquid. Liquid is a substance that flows to fit its container.Water Water is a liquid that is odorless‚ colorless‚ and tasteless. Water freezes and melts at 32*F (0*C). As water freezes it expands by one-eleventh. The amount of pressure on the water when it is freezing changes the melting point. Water that reaches 40*F it is at its maximum density. The
