TITLE : IDENTIFICATION OF BIOCHEMICALS IN PURE FORM AND IN COMMON FOODSTUFFS AIM: THE OBJECTIVE OF THIS EXPIREMENT IS TO PERFORM TESTS ON A VARIETY OF COMMON FOODS TO IDENTIFY THE CHEMICALS THEY CONTAIN AND TO TEST PURE SAMPLES OF BIOCHEMICALS TO GAIN FAMILIARITY WITH THE COLOUR CHANGES. RESULTS: TABLE 1 : BIOCHEMICAL TESTS ON PURIFIED BIOLOGICAL SUBSTANCES SAMPLE | TEST | OBSERVATION | Glucose | Reducing Sugar | The initial blue colouration of the mixture turns green

THICKNESS OF ZINC ON A PIECE OF GALVANIZED METAL Department of Biology‚ College of Science‚ University of the Philippines Baguio ABSTRACT The experiment was performed to be able to determine the thickness of zinc on a piece of galvanized metal. It also aimed for the students to be introduced to the reactivates of metals with acids as well as for them to develop some feeling for the size of an atom. In determining the thickness of the zinc coating on the metal‚ students‚ knowing the density of zinc

Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies. The composition of a standard penny is 97.5% Zn and 2.5% Cu. In the lab we will be using Beer’s Law (A=elc+b where A is solution absorbance‚ e is a constant called molar absorbency‚ l is the length in cm‚ and c is the concentration). Using Beer’s Law in this lab a colorimeter is used to find the

That being said‚ I seriously do not understand why fans of death metal enjoy the music – specifically the band “Cannibal Corpse.” I listened to their most popular songs “Make Them Suffer” and “Hammer Smashed Face” hoping to find something likeable about it and I could not. I had preconceived notions regarding the song

In the film Full Metal Jacket there are many leaders. The two I will focus on are Sergeant Drill Instructor (SDI) Hartman and ‘Joker’. They are two leaders with very different leadership skills. SDI Hartman is a strict and demanding leader who belittles his recruits to get their attention. Joker is a likeable character with a sense of humor and leads with honor and dignity. Both characters portray leadership skills to Private Pyle but the differences are night and day. The beginning of the
