My career was taking off as I was the youngest person to be hired by The Remedium Institute. For the first years of my career, I worked with a team of scientists on cancer research. We worked crazy hours. After countless nights of no-sleep, my team discovered a medicine that cured the cancer in rodents. We were days away from a cure in humans.…
Purpose: Explore the spread of a communicable disease using a simulation. Question: What is the effect of immunity on the rate at which a disease spreads? Hypothesis: If a higher percentage of people are immune to a disease, then the disease will spread more slowly, because fewer people will be able to contract it or pass it on.…
Determination of the Concentration of Acid in Gastric Juice Introduction Titration is a method where a solution of known concentration is used to find the concentration of an unknown solution. A standard solution is a solution of precisely known concentration. The aim of this experiment was to go over the use of pipettes, burettes, titrations and also to reinforce the concept of molarity.…

The Thermodynamics of Potassium Nitrate Dissolving in Water Introduction: This experiment focuses on thermodynamics or the study of heat and molecular randomness. It helps illustrate how and why potassium nitrate (KNO3) dissolves in water. When it dissolves, it dissociates into potassium (K+) and nitrate (NO3-) ions. These ions can also recombine into solid potassium nitrate. This reaction can reach a state where concentrations of ions remain constant or Ksp; which stands for the equilibrium concentration for the solubility product.…
