Abstract The basic principles of Osmosis and Diffusion were tested and examined in this lab. We examined the percent increase of mass and molarity of different concentrations of sucrose in the dialysis bag emerged in distilled water and the potato cores emerged in concentrations of sucrose. The data reinforces the principles of Osmosis and Diffusion‚ and in a biological context‚ we can simulate how water and particles move in and out of our own cells. Introduction Objective: 1. Investigate the

Determination of the Enthalpy for Decomposition of Hydrogen Peroxide Objective: To construct a coffee cup calorimeter‚ measure its calorimeter constant‚ and determine the enthalpy of decomposition and formation of hydrogen peroxide. Background: This experiment is a classic thermodynamics lab. In it‚ we attempt to measure the enthalpy (H) of a chemical reaction. The main obstacle is that this is a quantity that cannot be measured directly. It instead is observed as heat from one substance is transferred

Lung cancer kills more people in one year than all criminal and accidental deaths combined. These statistics are shocking‚ but the good news is that people are now well-informed about the risks connected to lung cancer. They know that their risk of contracting this terrible disease decreases if they either stop smoking or do not smoke at all. Unfortunately‚ the same cannot be said about other types of cancer. Many people are not aware that their everyday behavior can lead to the development of these

I used to believe the best way to avoid failure was to quit. Giving up before falling short meant never having to worry about losing or appearing incompetent. By insisting it was not worth my time to try‚ I could dissociate from my failures and blame them on my lack of interest or the activity’s low level of importance. This mindset went unchallenged throughout elementary and middle school when many of my chosen pastimes required minimal skill. It was not until high school that I began to feel

I am the most amazing person on earth. Do you know why I am so great? I am almost godly because of my great skill of tetherball. I hit the ball so hard that the post will fall over. Sometimes my arms power is so great that the string snaps. After snapping the ball would travel 300 feet before landing so the crowd members have a special spot called a splash zone. It was made just for me! The only thing that can compare to my power is the gods themselves! Maybe even my power is beyond this world

Marz Jhon V. Patricio QUANTITATIVE DETERMINATION OF THE ACIDITY OF SOFT DRINKS I. Introduction A. Principle Titration is a laboratory method that is the slow addition of one solution to another until the reaction reaches neutralization‚ which is often indicated by color change. Acid-base titration is the most frequently used procedure to determine the concentration of an acid or basic solution. This titration is also called as neutralization reaction. By adding an indicator to the solution‚ we will
