How much copper is in a penny? Introduction: This labs objective was to determine how much copper is in a penny. Concepts that were used for this lab were calibration curves, and oxidatoin of metal. Methods: Preparation of Solutoins In six different 50mL volumetric flasks there was 0.00 mL, 2.00 mL, 4.00 mL, 6.00 mL, 8.00 mL, and 10.00mL of the 5.00 g/L Cu^(2+)stock solution. 3mL of 15M ammonia was added into each flask, once the ammonia was added each flask was diluted with water to 50 mL then

Copper is a very versatile metal. It is used for very many thing, it’s very ductile so it’s used for wires and electrical work. It is also resistant to corrosion. We also eat it! Copper is a crucial part of our diet to protect us from infection. Copper is an amazing metal and is used for a lot of things, those things include building, electrical, and nutritional value. One amazing thing copper is used for is the fact that it good to build with. People use it to make pipes, and other things. It was

metals. Brass is usually made of copper and zinc, but there could be some other metals creating 300+ known brass alloys. The amount of copper in brass will affect basic characteristics of brass like color, strength, conductivity, etc. To find the amount of copper in brass one can use visible spectroscopy. Spectroscopy is the study of electromagnetic radiation. It originated as a study of visible light, and wavelength through a prism. Spectroscopy can show how much copper is in a brass solution by showing

Percent Copper in Brass I. Introduction Have you ever been to any orchestra show or home improvement store before? If you have, I’m sure you have seen those fancy gold-colored instruments or fancy door knobs or faucets from the home improvement store. Have you ever wondered what they are made up of? They are made up with the binary alloy called brass. Brass is a binary alloy made up of copper and zinc with an additional amount of lead and tin(Brass in Focus, Angela Vessey,2004). Its

This experiment was designed to test which liquids would oxidize iron the fastest. Four iron cylinders were placed in separate glass jars that contained four different liquids: tap water, saltwater, bleach and Sprite. They were then left to sit for about six days. The mass of each cylinder was measured before and after the experiment in order to find the accumulated rust. The results of this experiment show that the iron in the liquid bleach accumulated the most rust over a six day period. This proves

manipulate the state of copper by taking copper through four different forms and to observe and understand the method behind each reaction. The transformations include starting from 0.1588g of Copper(II) Chloride dihydrate to produce Copper(II) hydroxide. Copper(II) Chloride dihydrate was dissolved in water forming a light blue colour and Sodium hydroxide was added in order to form Copper(II) hydroxide a dark blue precipitate. In this reaction Sodium Chloride is soluble and Copper hydroxide is insoluble

In this lab we will be heating up substances and use them to galvanize pennies. When you heat up the zinc, and then coat the penny in it, it then galvanizes the penny. Meaning, it helps protect the penny from oxygen and water. Afterwards, you will need to record data such as the mass of the penny. This helps keep track of what physical traits are being changed during this experiment. On part B of this experiment, you will be heating up the now galvanized pennies in order to see what reaction you

1. Ancestry Discovered in approximately 3000 BC, silver is one of the oldest elements known to man. Why was it so easy for miners in Turkey and Greece to discover, one may ask? Silver is also one of the most abundant elements found on earth and was not difficult to come across when mining mountains and rocks. (Silver, 1) The exploration of silver mines in Laurium, Greece is significantly responsible for the rise of Athens in 600 BC. Additionally, in medieval times, German mines became the main source

The purpose of this lab is to figure out the mass percentage of copper in a penny. Furthermore, by doing this lab we will practice using a spectrophotometer and review the names of equipment such as volumetric glassware, pipets, and volumetric flasks. Background: Pennies before 1983 were made with pure copper, while pennies minted after 1983 have a zinc core and a copper shell. The difference between the two types of pennies is the reason why we have to use a penny minted after 1983 for this experiment

How Otzi the iceman die? Otzi the iceman, a figure whose body has been preserved in the ice of the Alps has unveiled the secrets to copper-aged life and from the evidence found, i have come to the conclusion that Otzi died because he was in combat with two other people who were trying to take him for a sacrifice. Otzi had slits on his wrist, a punctured thumb, a damaged wrist bone, and a ½ inch deep zigzag cut in his right hand.Otzi also had a dagger in the hand with the zigzag cut. From this evidence
