Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

Joe Schmoe Period 3 March 8‚ 2013 Lab Report: Empirical Formula of Zinc Chloride (ZnCl) * Purpose The purpose of this experiment was to learn how to determine the empirical formula. Empirical means “based on experimental evidence.” * Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1.00g and 1.25g. As the reaction

Lab Report 1: Natural Selection Introduction: In today’s lab we learned how natural selection and survival of the fitness took place in Darwin theory by testing it out with four different utensils which were Spoon‚ Fork‚ chopstick‚ and clothespin which represent the four different types of bird beaks. Our goal was to see which one utensil ( bird beak) would outcome the other four utensil ( bird beak) by being able to survive with the limit amount of food‚ the environmental chances‚ and see who

EXPERIMENT No. 2 The Simple Pendulum Abstract A simple pendulum is one which can be considered to be a point mass suspended from a string or rod of negligible mass and allowing it to sway back and forth in a place. The objective of this experiment is to observe the motion of a simple pendulum‚ study simple harmonic motion‚ determine some factors that affect the period of a pendulum‚ and measure the value of acceleration due to gravity by use of a simple pendulum. The materials used were inelastic

Light of Darkness In the story‚ "The Pit and the Pendulum"‚ written by the infamous Edgar Allen Poe‚ written in 1843‚ places a man during the time of the Inquisition who is incarnated. Beginning the story‚ this man‚ who remains unnamed‚ receives a death sentence and immediately faints. Upon waking he finds himself in a completely dark room. Scared that he is inside a tomb‚ he moves around to reinsure himself. Upon exploring this darkened room he accidentally trips and falls finding that his

Z. K. L3 A THE SIMPLE PENDULUM • General Background: A mass m hanging from a string whose length is L and a pivot point on which this mass is fixed are what a simple pendulum (which was discovered during the 10th century by Ibn Yusuf) consists of. During the 17th century‚ it is developed by some physicist‚ especially by Galileo. When the mass hanging from the string is released with an initial angle‚ it starts to move with a periodic motion. The motion can be approximated as a simple

The purpose of this experiment was to acquaint the students with basic laboratory procedures‚ methods‚ and techniques; to introduce the use of basic laboratory measuring devices; to demonstrate different methods of manipulation of numerical quantities. DENSITY AND SPECIFIC GRAVITY Materials and Methods Part 1: Density of an Unknown Solid 1. We first were asked from our laboratory instructor to attain an unknown solid and were asked to note down the number of the solid. 2. Determine

means‚ the relationship between periodic time and length for a simple pendulum. Apparatus: Pendulum bob‚ light string‚ clamp stand‚ meter ruler‚ stopwatch‚ graph paper. Theory: The relationship between two physical quantities can be determined by graphical means. For a simple pendulum‚ the relationship between periodic time and length is given by the equation Where‚ T is the periodic time‚ 1 is the length of the pendulum string and g is acceleration due to gravity A graph of periodic time
