In the Penny Cleaning Lab‚ my hypothesis‚ which stated that the lemon juice would be the best at cleaning the penny since it is an acid and acids are particularly good at cleaning metallic substances‚ was indeed valid. First‚ we started out with 1mL solutions of all the substances in the test tray. We dipped the pH paper in each solution for about a second and recorded the pH level for each substance. Before starting‚ we noticed that all the pennies were in some shade of brown‚ which I predicted

Dylan McFarland 9/15/14 Honors Chemistry Richardson Lab: Measuring the Density of Pennies Pre-Lab Questions: 1. The equation that relates density‚ mass‚ and volume is: density = mass / volume. 2. All substances have unique densities‚ so if you are able to find the density of a substance‚ you can properly identify it. 3. We measure irregular-shaped objects with the use of water displacement because it would be nearly impossible to get the exact measurements

Percent Composition of a Penny Background Information: Post-1983 pennies have a copper jacket and a zinc core. We hope to determine the percent composition of these two metals. This will be done by reacting the zinc with hydrochloric acid to form zinc ions in a single replacement reaction. The acid reacts with the zinc but not copper. The reaction of zinc metal with the hydrochloric acid (HCl) produces zinc chloride and hydrogen gas. Safety: Wear your safety goggles and apron If you spill Hydrochloric

Most people‚ without paying attention‚ drops their pennies on the floor and become rusty over time. The reason for this is the air and other things that come into contact with this penny. A cleaning solution can be described in chemical formula of Acetic acid‚ a colorless organic compound‚ which has a pH

the U.S should stop making pennies. Pennies just cost to much to make‚ and they waste our time counting them over counters and at food service windows. Also‚ other countries have banned the penny and so should we. The penny costs more than its worth. Even though‚ pennies aren’t worth that much‚ the money wasted to produce them can add up to millions of dollars over time. It costs 2.4 cents to produce a single one cent coin.(Story) Taxpayers lose money every time a penny is made. It may not seem like
