n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

latent heat of fusion for water Specific latent heat is the amount of heat energy that is needed to change the state of one kilogram of a specific substance‚ whether it’s boiling or melting‚ without increasing or decreasing the temperature of the substance. Specific latent heat of fusion is the amount of heat energy that is needed to change a specific substance from solid to liquid. The specific latent heat of fusion for water is 334 KJ/ KG. Each substance has its own specific latent heat of fusion

they do provide some sense of the issues to be faced. Second‚ diet problems that are missing the constraints that force variety into the diet can be terribly embarrassing. It has been said that a hospital in New Orleans ended up with an LP solution to feed each patient only castor oil for dinner because analysts neglected to add constraints forcing a well-rounded diet.

The Summer Heat By Ishan Rodman Sophomore Humanities Project May 20th‚ 2016 Mr. Eason Mrs. Ihrke The sky was ablaze but this was a different kind of fire. A warm fire‚ one that enveloped me and gave hope that we would no longer be afraid and no longer be scared. We stepped out of the shade of the barn and climbed over the ridge. We could all see one thing‚ men in dull gray uniforms running out of the city. Towards the south a sea of blue and green push forward flooding the city washing it

MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total
