Penny Press Until the early 1800’s‚ newspapers in England and America were expensive and therefore exclusive to the wealthy and literate minority. On average‚ newspapers would cost around six cents per issue and were usually sold through subscription only. Readers would have to pay for a years’ worth of newspapers when first signing up for a subscription‚ and that cost could be a middle-class worker’s week’s wage. Most people could not afford newspapers and therefore could not receive daily news

Copper is an element that occurs in minor amounts in the earth’s crust. Estimates of average crustal prevalence are on the order of 0.0058 percent by weight. Deposits considered to be economically recoverable at current market prices may contain as little as 0.5 percent of copper or less‚ depending on the mining method‚ total reserves‚ and the geologic setting of the deposit. Here is the flow sheet on how to process copper from Zenith. Copper Process Flow Sheet: Copper ore is first quarried from

Based on the class data‚ the density of the penny changed dramatically between 1980 and 1985. From 1975 to 1980‚ the penny became 1.40g/mL less dense and from 1980 to 1985‚ the density dropped by 0.626. With this data and the percent composition equation we were able to determine that the second metal in the penny is Zinc with a density of 7.14g/mL. Using scholarly online sources‚ I was able to confirm this data concerning the second metal to be correct. The United States Mint’s website states that

Chemical analysis of over than 600 water samples taken from streams and springs in the mining region and surrounding area of pit showed extensive changes in water quality and composition due to the passage of water through waste dumps and mining region. In this research the quality and composition of water in these two regions were analysed and

Abstract The purpose of this lab was to study the composition of hydrates. Hydrates are ionic compounds that are chemical compositions made of water and salt. A main objective was to remove water from the hydrate by heating‚ and determine the amount of water that was in the hydrate. After doing this‚ one had to predict the empirical formula for hydrated copper sulfate. In doing this lab‚ one was able to see the gradual change in the composition of a hydrate into an anhydrous salt. The lab was

experimental % of copper (Cu) in a post 1982 cent? In this lab‚ we will determine the % composition of a modern (post-1982) penny by using a strong acid called nitric acid (HNO3)‚ to react and dissolve the zinc core‚ leaving only the copper coating. Once only copper remains‚ we will then compare its’ absorbency to the other five post-1982 penny Cu concentrations made in this lab. INTRODUCTION: Before 1982 the US penny was made of pure copper. Because of the high cost of copper‚ the US government

Should Pennies be a Valid Currency? How many people keep their pennies compared to how many people just toss them in the leave one/take one trays at the gas stations or tell a cashier to keep the change? Is the cost of making a penny worth it? According to the US Mint‚ it costs 2.41 cents to make a penny. It costs two and a half times more to make the penny than the coin is worth. In most cases‚ businesses can round up or down to the nearest five cent with it not affecting their tills drastically

Imagine a world without the penny. No more happy children who think good luck will come their way when they find a penny heads up on the ground. No pennies around to make that old tin cup clink and brighten the day of some desperate homeless man. Charities‚ instead of thriving‚ would suffer due to penniless penny drives. Jobs would be lost due to the lower demand for zinc that could be mined and produced into American money. Most importantly‚ a significant part of history would be thrown away and
