Hypothesis: I believe that alcoholic compounds with bigger relative formula mass will release more energy in combustion reaction than the less alcoholic hydrocarbons compounds. Equipment: Different types of alcohols in spirit burner (CH4‚ C2H6‚ C3H8‚ C4H10‚ C5H12)‚ Thermometer‚ water‚ beaker‚ scale‚ measuring cylinder‚ tripods‚ clamp‚ gauze‚ heat mat‚ lighter or matches. Hazard: Most of alcohol we using are flammable‚ irritant‚ toxic and harmful. 1 provide spirit burners which have removable

Differential Scanning Calorimetry (DSC) was carried out to investigate the thermodynamic properties of CXB‚ different carriers‚ PMs and SD preparations. Their thermograms are represented in Figures (9-14). The thermogram of CXB in Figure (9) was characterized by single‚ sharp endothermic peak at 165±0.56°C which represents the melting point of CXB. Some researchers reported that CXB melting point ranging from 160.79–164.64°C (127)‚ and Paradkar A. et al. (2002) reported that sharp endotherm corresponding

Vir Heroicus Sublimis (1950-1951) by Barnett Newman Upon reading the assignment I had some difficulty picking out the piece of art I would write about. Searching for a piece I disliked or was indifferent to became a difficult task. It would obviously be followed with the question why. Why did I dislike it or was I indifferent towards it? I realized that for everything I came across there were multiple reasons as to why I believed I disliked the piece or was indifferent to it. Up until I came

Almost every aspect of their art is antonymous and extremely different‚ from their art practice‚ to the meaning they constructed in their works‚ to the audience and world they reflected. Jackson Pollock wasn an Abstract Expressionist who used the Action Painting style‚ as opposed to the Colour Field Painting style. He was active in the 1940s and 1950s‚ joining a wealth of artists moving to the newly established art capital of the world. Pollock ’s art practice

------------------------------------------------- Abstract Business ethics is a form of professional ethics that examines ethical principles and moral or ethical problems that arise in a business environment. It applies to all aspects of business conduct and is relevant to the conduct of individuals and business organizations as a whole. Applied ethics is a field of ethics that deals with ethical questions in many fields such as medical‚ technical‚ legal and business ethics. In this paper we will

Weigh an antacid table in a weighing boat and record the mass (+0.01 g). Transfer the tablet to a clean mortar and crush the tablet into a fine powder using the pestle. 3. Weigh about 0.2 grams (+0.01 g) of the ground up tablet powder and transfer it to a clean 250 mL Erlenmeyer flask. 4. Transfer

In this experiment‚ we used acquired observational data to develop an activity series describing the relative reactivity of the metals being tested. The elements within a periodic table often show different trends in physical and chemical properties depending on the period or group they are apart of. In a periodic table‚ elements are arranged by increasing atomic number in horizontal rows called periods. The atomic numbers represent the number of protons in each element. The periodic table is also

Aim: The aim of this experiment is to convert copper metal through a series of intermediate copper compounds back into copper metal. By weighing the copper at the beginning and at the end of the experiment the percentage yield can be determined. Method: The experiment was carried out as outlined in the practical manual.
