Melting Point and Boiling Point of Organic Compounds Bongo‚ Sayre‚ J1 1Student‚ Organic Chemistry 1 Laboratory / B11‚ School of Chemical Engineering‚ Chemistry and Biotechnology‚ Mapúa Institute of Technology ABSTRACT The melting point of a substance is the temperature at which the material changes from a solid to a liquid state while the boiling point is the temperature at which it changes from liquid to solid. In this experiment‚ the main objectives were to determine the effects of the following

Three Main Types of Volcanoes The three main types of volcanoes differ in shape‚ size‚ and make-up; the differences partly result from the different types of eruptions. Volcano Type Volcano Shape Volcano Size Volcano Materials Eruption Type UTAH example Cinder Cone Steep conical hill with straight sides Small less than 300m high cinders Explosive Diamond Cinder Cone‚ Washington County Shield Volcano Very gentle slopes; convex upward (shaped like a warrior’s shield) Large over 10s of kms

Industrial Separation Research a) Identify a mixture that is separated industrially: Olive oil b) Identify which ‘sphere’ it is obtained from: Biosphere c) Identify the industrial separation processes used on this mixture: Crushing/grinding: The olive fruit is crushed and ground by a metal hammer in a mill to make a paste. Beating: The olive fruit paste is added to water is additionally beaten to extract more oil from the olive cells. Salt can be used to assist osmotic breakdown [of the cells]

Tolentino Maria Oyervide EXPERIMENT #4 IONIC AND COVALENT COMPOUNDS Abstract: This experiment was divided in four steps to find the electrical conductivity of covalent and ionic solutions. There were four unknown solutes A‚ B and C. Each had a specific weight and was dissolved in a certain amount of solute to form either the covalent or ionic solution. Covalent compounds are made up of molecules which are electrically neutral. Ionic compounds are composed of ions‚ which are positively or negatively

Nupoor Matieda October 10‚ 2014 PD 9/10 Lab Report Separation of a Mixture of Sand and Salt Goal(s): To separate a mixture of sand and salt and to find the percent of each component by mass of each mixture Background Theory: A mixture is a combination of two or more pure substances in which each pure substance retains its individual chemical properties. Mixtures can be separated by physical processes such as filtration and evaporation. Filtration is a process where solids

The short stories “The Third Wish” written by Joan Aiken and “Those Three Wishes” written by Judith Gorog share the main similarity of having a three wishes motif. These two stories may share a similar motif‚ but they differ in several important aspects. “The Third Wish” and “Those Three Wishes” differ in the way the story is told. Also‚ “The Third Wish” and “Those Three Wishes” are different‚ because they use the three wishes motif in different ways. Last but not least‚ the stories have a different

Medieval society was divided into three groups known as the “Three Estates” (the Church‚ the Nobility‚ and the Peasantry). Follow this analogy by placing contemporary western society into three groups (or three modern “estates”). Name what these modern estates would be and describe what they would look like. Use your imagination‚ but limit yourself to three categories. Dr.Rock HUMN 101 18 March 2012 The Three Estates The classical Three Estates (social classes) during the mideival period

colonies in America had to make was to become a society quite different from that in England. By 1763 although some colonies still maintained established churches‚ other colonies had accomplished a virtual revolution for religious toleration and separation of church and state. During the mid-1600’s England was a Christian dominated nation; the colonies‚ however‚ were mainly Puritans. When Sir Edmond Andros took over a Puritan church in Boston for Anglican worship‚ the Puritans believed this was done
