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

Careful observations are the first step in this process. An observation is a fact obtained with the senses. ------------------------------------------------- You might think that a burning candle is pretty simple. But

Discussion The purpose of the Density Lab was to determine the identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart‚ taking into account error analysis and finally classifying the substances. In order to calculate this density‚ we first found the mass of the container that was to be holding the substances. We then found the volume of the substance‚ and lastly determined the mass of the container and substance. We subtracted

Standardize a solution of potassium manganate(VII) by an iron (II) salt (ammonium iron (II) sulphate) Introduction Oxidation numbers describe the number of electrons the atom will gain or lose during a reaction. Each atom in an equation can be assigned an oxidation number according to certain rules. If the oxidation number of an atom increases as you go from the left side to the right side if an equation‚ oxidation has occurred (electrons have been lost); if the oxidation number decreases

Burning Money Chemistry Demonstration Principle You soak a note in ethanol (alcohol) and it will burn when lighted‚ leaving the note untouched. This is because alcohol is more flammable‚ and burning alcohol causes it to vaporize‚ along with the water present in the solution. This removes heat from the note and prevents it from reaching its combustion point.
