Results 10 Calculations 14 Discussion 20 Conclusion 21 Recommendations 21 References 22 Appendices 22 Abstract This experiment was performed in order to determine the molarity of a solution and the percent by mass of acetic acid‚ CH3COOH in vinegar. Acetic acid is monoprotic and belongs to the carboxyl family of organic compounds. The titration method is used to neutralize the acids by using the standardized sodium hydroxide solution. It reacts with bases which is sodium hydroxide‚ NaOH to form

Chemistry Batteries [Chemistry HSC Course-1] What is an Anode? An anode is the negatively charged electrode of an electrical device but in this a primary cell‚ that supplies current. What is a Cathode? A cathode is the positively charged electrode of an electrical device which in this case is a primary cell‚ that supplies current. What is Current? A flow of current which results from the ordered directional movement of electrically charged particles. A current is the rate of flow of charge

scalloped‚ but how about taking the place of a car battery? If a potato can replace a AA battery and light up a light bulb‚ who’s to say multiple potatoes couldn’t serve the same purpose in a car? Potatoes use the acids within them to start a reaction between the copper and zinc wires on either side of it. This reaction causes the flow of electrons passing through the wires and using the positive and negatively charged electrons to power the bulb. Car batteries also run off a positive and negative charge

Thermochemistry (((CLASS INFORMATION)) INTRODUCTION Thermal chemistry was intended to display that chemical reaction and phase changes involve energy. The energy of heat was presented when a change in temperature difference was evaluated. Chemical reactions in a calorimeter were used to determine the amount of heat produced by a reaction. Reactions that absorb heat were noted as endothermic‚ and reactions that release heat were noted as exothermic

The dry cell or Leclanche cell was the first commercial battery and therefore had a big impact on society. It is the most common and the cheapest of the commercially available cell and is most widely used in torches‚ portable radios and battery-operated clocks. It is best used for low drain appliances‚ which need only small currents such as portable items (radio). It consists of a zinc outer casting‚ the anode‚ an aqueous paste of ammonium chloride and a mixture of powdered carbon and manganese

Can you catch more flies with honey than with vinegar ? Positivity or optimism is something observed in the field of psychology that refers to two phenomena: That people tend to observe a neutral situation as mildly positive‚ or that people feel good at any given moment and this is easily observable to other individuals around a person. With 8th graders thats an important factor for school work and social life as the work 8th graders do in school is critical for their grades and it is very important
