Experiment 12 Influences of Molecular Shape and Intermolecular Forces on Physical Properties By Hannah Kloss Chemistry 112L- 01 --- Eric Boakye November 10‚ 2014 Physical properties are properties that can be measured and seen in an object. An example of a physical property of an object would be the color‚ mass‚ solubility‚ volume‚ or the polarity of an object. A physical property can change the appearance of an object‚ but that does not mean that the chemical composition has to change

Chemical Periodicity ------------------------------------------------- ABSTRACT The experiment chemical periodicity shows the properties and reactions belonging to group IA‚ IIA‚ and IVA. Proper procedures and observations were done to determine the solubility‚ physical state‚ color‚ and appearance of the compounds namely Li2CO3‚ Na2CO3‚ K2CO3‚ CaCO3‚ and BaCO3. The results shows that Li2CO3‚ Na2CO3‚ K2CO3 were soluble in water‚ while MgCO3‚ CaCO3‚and BaCO3 were not soluble. All of these compounds

Chemical Bonding Lab Chemical compounds are combinations of atoms held together by chemical bonds. These chemical bonds are of two basic types—ionic and covalent. Ionic bonds result when one or more electrons from one atom or group of atoms is transferred to another atom. Positive and negative ions are created through the transfer. In covalent compounds no electrons are transferred; instead electrons are shared by the bonded atoms. The physical properties of a substance‚ such as melting point

Determination of the Rate Constant for a Chemical Reaction Department of Chemistry Abstract This experiment was performed to determine the rate constant k‚ for hydrolysis of tertiary butyl chloride to tertiary butanol. The solvent system for this reaction is 45% isopropyl alcohol and 55% water. The rate of hydrolysis of t-butyl chloride is measured by the decrease in the concentration of this reagent with time. The rate of decomposition of t-butyl chloride must be equal to the rate of formation

DETERMINATION OF FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low‚ because of low sugar content and high fruit acid content‚ this makes the fruit taste sour. During the ripening process the fruit acids are degraded‚ the sugar content increases and

Free will Vs Determination Do you make your own choices or your destiny has been decided for you by circumstances behind your control? For thousands of years‚ this question has puzzled philosophers‚ scientist and anyone who thinks about how they choose to act and live. Part of the complexity of the matter is related to the metaphysical nature of the subject which has a close affinity with the concept of GOD. Some people think that "Everything" that happens in nature and life
