by dissolving a solute in a definite amount of solution which is saturated. Specifically‚ the goal of this experiment is to prepare a saturated solution of Na2C2O4 in water at different temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring how much KMnO4 was needed to help Na2C2O4 reach chemical equilibrium at certain temperatures. In doing this‚ we will have fulfilled

Enzymes are biologic polymers that catalyze the chemical reactions that make life as we know it possible. The presence and maintenance of a complete and balanced set of enzymes is essential for the breakdown of nutrients to supply energy and chemical building blocks; the assembly of those building blocks into proteins‚ DNA‚ membranes‚ cells‚ and tissues; and the harnessing of energy to power cell motility‚ neural function‚ and muscle contraction. With the exception of catalytic RNA molecules‚ or

Instead‚ by increasing the concentration of the cathode‚ the voltage of the galvanic cell will decrease due to the equilibrium shift to the left. The highest concentration (1.5 mol dm-3 ) was the lowest out of the 3 trials at 1.68 volts‚ thus proving that the higher concentration the lower the voltage. When the concentration of the product decreases‚ it will drive the equilibrium to the right to minimize the impact. Although‚ the lowest calculation (0.5 mol dm-3) is not necessarily the highest out

The beginning of the documentary‚ “The Invisibles” talks about the journey to a new world‚ United States‚ the many risks those who try to escape the economic problems take just to get across the border. Many distasteful thing happen to families who try to reach North America‚ people are kidnapped‚ tortured in an inhumane matter‚ and killed in front of the others. This establishes fear among all other kidnapped to and all other who attempt to cross the border in hope of a better life. One thing that

Defense Mechanisms Denial: Refusal to accept reality. Difficulty accepting what is true. Ex) My family could not accept the fact that my niece was diagnosed with a fatal‚ cancerous brain tumor. Displacement: Emotion pointed on something that brings lesser risk. Ex) When I got my first F in school I went and told my mom instead of my dad because she takes things lighter. Intellectualization: Focusing on only intellectual parts of a situation to avoid direct emotional ties

emblem of true freedom‚ then America is the stereotypical answer for a number of people. To which‚ during the reconstruction era‚ a division of people who were both legally free and had the same opportunities‚ but only differed in skin color‚ upheld racial segregation. Hence in the novel Invisible Man‚ the protagonist represents a distorted view of America through a symbolic Battle Royale for equality which is coupled with an erotic dance to leave minorities “stripped” of their dignity.

Torque and Equilibrium Purpose: Apply principle of static equilibrium to determine a coefficient of friction. Research Question: What is the coefficient of friction between a meter stick and wall? Hypothesis: Tying a piece of string on to the end of a meter stick‚ put the other end of the meter stick against the wall so that the meter stick is horizontal and does not slide down the wall. Hang a weight on the meter stick sliding it to a point where the meter stick is about to come off from
