    Abstract The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver‚ ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm‚ and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation‚ this means that the more diluted the solution of 95% ethanol was‚ the less oxygen gas collected

    a good estimation of the hydrocarbons in place in a reservoir. That is‚ he must be able to determine the Oil Initially In Place (OIIP) and the Gas Initially In Place (GIIP). Many factors have to be carefully considered and the one discussed in this lab is the Bulk Rock Volume and how it is acquired. Bulk rock volume is really the gross rock volume of rock above any hydrocarbon-water contact. It can be determined by mapping and correlating contour maps of the given area. The net-to-gross ratio

    AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =
