Purpose To utilize two different methods of determining the initial velocity of a fired ball, namely a ballistic pendulum and treating the ball as a projectile, and then compare these two calculated values. The loss of kinetic energy from firing the ball into the pendulum is also an area of . . .

I attended Saint Joseph's University from 2006 to 2010. I started off majoring in Biology, switched to Chemistry after being terrified of the memorization required for Organismic Biology, and finished with a 3.56 GPA.
Introduction Tyrosinase is an enzyme involved with that catalysis of monophenols and catechols. Specifically in mammals, tyrosinase catalyzes two steps in the biosynthesis of melanin pigments from tyrosine. The pigment produced from this reaction is used in eyes, hair, and skin. In this laboratory . . .
Purpose To determine the relationship between force, displacement, potential energy, kinetic energy, and work by using a force sensor to pull a spring and also to push a cart. Hypothesis The work done on the spring will be greatest at its furthest displacement and that the greater the work done on the . . .
Unlike the well know and oft studied chemistry of double bonds between carbons, the chemistry of boron-boron double bonds is for the most part unexplored. It is believed that boron should behave similarly to carbon due to its relativity to the element on the periodic table. Anions containing boron double . . .
Purpose To determine the relationship between force, mass, and acceleration using a cart attached to a pulley with varying weights. Hypothesis If the mass of the weights attached to the pulley is increased, the force exerted on the cart and the acceleration of the cart will also increase. Labeled . . .
Introduction The proposed particle in a box experiment uses theories from quantum mechanisms in order to determine and prove the behavior of a molecule. In the experiment performed, various dye molecules were observed using a Spectronic 21 spectrophotometer to determine their wavelengths of maximum . . .
It has oft been debated whether or not there is justification behind the taking of a human being’s life via the assistance of a physician. This procedure has been reserved for unique situations, but even still, the allowance of this practice has opened a Pandora’s Box; there are innumerable legal and moral . . .
