The purpose of this experiment was to determine the effects of temperature on the elasticity of rubber bands. There were three hypotheses: If the 0.157 cm rubber bands are heated to about 100˚C in water for one minute‚ then the rubber bands will stretch to approximately 60 cm; If the 0.157 cm rubber bands are cooled to 0˚C in water for one minute‚ then the rubber bands will stretch to approximately 40 cm; If the 0.157 cm rubber bands are left in room temperature water for one minute

Candide Voltaire‚ a French philosophe and writer‚ wrote this document during the Enlightenment. He illustrates his opinion on many Enlightenment ideas‚ such as Leibnizian optimism‚ deism‚ and religious tolerance. He impacted many people‚ including Benjamin Franklin and Thomas Jefferson with his belief of religious toleration and civil rights. His view on organized religion also influenced the French Revolution. One of the Enlightenment views Voltaire addresses is Leibnizian optimism‚ or the

Alum Synthesis: The Chemical Process of Recycling Aluminum Introduction By recycling aluminum cans‚ the costs and energy savings are dramatically more resourceful and efficient than producing aluminum from what it is naturally found in‚ bauxite ore. The process of recycling aluminum to produce potassium aluminum sulfate‚ a common alum‚ will be done through a serious of chemical reactions. Through this reaction‚ percent yield will be determined. Materials and Methods The mass of a 250 mL

THE PROCESS OF FERMENTATION THROUGH DIFFERENT KINDS OF SUGARS In order to produce ethyl alcohol fermentation‚ we had to determine what sugars used‚ such as glucose (a single sugar) sucrose (table sugar) and lactose (milk sugar) will react with yeast to produce ethyl alcohol fermentation. My hypothesis is that the sugar lactose would produce the highest amount of bubbles and ferment. INTRODUCTION: The significance of fermentation is a lengthy process that has been practiced by humankind

result in criminal charges being filed. If carried out by individuals unskilled at chemistry they could result in serious bodily harm. MDMA ("Ecstasy") is a semi-synthetic compound which can be made relatively easily from available precursors. Synthesis instructions exist which can be followed by an amateur with very little knowledge of chemistry. However‚ people with less than 2 years of college chemistry experience would probably not be capable of sucessfully synthesizing MDMA‚ and would either

Abstract This study entitled “Ethanol Production from Waste Banana Peelings” aims to produce an alternative way in producing energy. Banana chips‚ banana con hielo‚ banana cue and other Filipino delicacies made up of banana are some of our favorite foods. But after the consumption of the flesh‚ we are just throwing out the peelings as garbage. Our country today is facing two major problems‚ energy crisis and proper waste disposal. This study used waste banana peelings

Abstract Introduction The acylation of the α carbon position of a carbonyl group is one of the greatest breakthroughs that has benefited chemists in organic synthesis particularly when in need of building a carbon skeleton of interest in a molecule. For one to be able perform this acylation technique‚ there are two mar approaches which are employable. The first method involves the deprotonation of the α-Carbon atom which has a pKa known to be ̴20 through the use of a strong base for instance

Graph 2. Relationship Between ABV and Time in Secondary Fermentation There is a clear positive trend between the two variables: with the passing of time‚ the ABV is increasing. The trend seems to be linear and also relatively constant‚ with a slope of 0.0405. This may be because only a very limited number of trials were collected. The rate of the graph may possibly change throughout the time intervals‚ like that of the graph in primary fermentation. As the alcohol content in the must increases‚ this
