Determination of % Composition of Pennies Using Redox and Double Displacement (Precipitation) Reactions Introduction: Oxidation involves the gain of electrons of hydrogen or the loss of oxygen or decrease in oxidation state. If zinc completely reacts with HCL‚ then the theoretical yield of copper should be equivalent to the actual yield. Purpose: In this lab‚ we will determine the percent composition of a modern (post-1982) penny by using a strong acid to react and dissolve the zinc

Whale Rider: Inner Strength and Determination The film Whale Rider opens with a man‚ Porourangi‚ standing next to his wife as she gives birth to twins. Unfortunately‚ the mother and the son do not survive leaving only the girl who is named Paikea. This greatly upsets Koro‚ Porourangi’s father. As the reigning chief of the Maori people‚ he would have taught Porourangi’s first born son in the ways of their ancestors to become the next chief (Wald 2006). After experiencing such a devastating loss

Specific Heat: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat. The relationship does not apply if a phase change is encountered‚ because the heat added or removed during a phase change does not change the temperature. Q=mcTDelta Abstract: In this experiment we are trying to determine the

PREPARATION OF ASPIRIN AND DETERMINATION OF THE MELTING POINT Ferrer‚ Lara Melissa V. Faculty of Engineering University of Santo Tomas Manila‚ Philippines ABSTRACT This experiment involved three steps: synthesis of aspirin‚ isolation and purification‚ and the estimation of purity of the final product. The synthesis involved the reaction of salicylic acid and acetic anhydride in the presence of a catalyst‚ phosphoric acid‚ H3PO4. When the aspirin was prepared‚ it was isolated and filtered. The percentage
