materials we use today are actually mixtures of pure substances. The separation of these materials into their pure substances can be quite challenging. When we are discussing separations of a mixture that contains pure substances‚ it all depends on whether you can separate the substances by physical means. That means‚ utilizing each substances physical properties such as boiling point‚ melting point‚ and magnetism. Separation of a Mixture of Solids Lab Report Assistant

the quantification of albumin and casein were performed and analyzed after extraction of the said proteins from their respective sources. Isolation of proteins was initiated by the breakage of the cell wall / membranes in three different ways. Homogenization of invertase‚ albumin and casein were achieved via grinding process‚ addition of 1M acetic acid and acidification by 0.1M hydrochloric acid correspondingly. Extraction of invertase and casein involved precipitation through the utilization of 95%

DNA EXTRACTION In extracting chromatin from the cells of wheat germ there are seven steps to follow. The optimal cell to use would be the polyploidal eukaryotic. Eukaryotes have nucleus membrane-bound organelles‚ while prokaryotic does not. The polyploidal eukaryotic cell has DNA that is held in the nucleus while the prokaryote has DNA that floats freely around the cell. The DNA of eukaryotes is more complex and extensive than the other. Prokaryote is a bacterial cell that

Name: Leung Chun Wai Student no.: G20554292 Topic: (NT3048) Smoke extraction design for large space such as atrium 1. INTRODUCTION Atrium inside a building is an old architectural concept for about two thousand years. This concept has been developed and extended to modern buildings. Current trend of atrium design provides an ‘ideal’ external environment to the occupants with a large undivided space. The major problem for fires in atrium is hot and toxic gases accumulating and go down in the atrium

substance to their pure state. By changing the state of matter from solid to liquid and vies versus during the experiment the student will be able to see the physically means of each substance. During the experiment the student will use varies techniques and materials to separate the substances. The students will use a scale to measure the mass in grams of the substance and subtract the original total to the new total each time to obtain the net mass of the substance. The students will separate

EXTRACTION OF METALS SUMMARY Most metals exist in compounds in rocks in the Earth’s crust. Many of these ores contain oxides or sulphides of the metals. The compounds need to be reduced to produce the metals as elements. Metals are very useful to us because of their special properties. Reduction means removal of oxygen or gain of electrons. Carbon is a good chemical reducing agent because it readily combines with oxygen‚ but it is only useful for the metals below it in the Reactivity
