Exercise 1 Polymers – An introduction to Organic Chemistry Group 3 Jude Marchoni C. Tampus Meryl Marie Susan Chua Pearl Pontillas Paolo Pepito Gaia Casas I. Abstract: (Paolo) In this experiment we will be testing what would happen to the polymer when we add borax to it. A polymer is a compound made up of large molecules often in a solid state. Polymers are chemically formed by 100 to 10‚000 small molecules called "monomers". Monomers occur in molecular units or patterns

October 13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden

Jashandeep Gill Gammellos Chemistry Density is one of the fundamental principles of physics. Density is the reason why a plank of wood floats on water while a piece of metal several times smaller will sink. Density of an object is measured in g/cm³ or g/cc. The equation is D=M/V‚ D being the density of the object‚ M being the mass of the object‚ and V being the volume of the object. Mass is the space an object takes up. It is the amount of matter present in an object. Mass is measured using
