Copper and Zinc Composition Percentages in Pennies Introduction. The United States Mint sends copper and zinc to a fabricator‚ which creates coin-sized discs called planchets. The planchets undergo the coining press at the Mint where they are stamped as genuine United States legal tender coins. The purpose of this experiment is to determine the accuracy of the copper and zinc composition percentages in a random sampling of pennies. The penny was dissolved to make aqueous copper ions and four copper

Research how a basic roller coaster works. What determines how high your loops or hills can be? What determines how many features you can have in one roller coaster? Something that determines how high you’re loops and hills go is how much kinetic energy the coaster has before going into those loops and hills. If a coaster does not have enough kinetic energy to go up and around a loop or up a hill‚ then it will get stuck. Also‚ if the coaster carts don’t have enough space between them‚ they could

will become positively charged. Electric charges can be characterized by repulsion between two positive charges or two negative charges‚ and can also be attraction between a positive charge and a negative charge. In this experiment‚ we were able to determine the presence of electrostatic charges with the use of an electroscope. It is performed by using three different kinds of rod (plastic‚ glass‚ and PVC)‚ each rubbed with silk cloth‚ flannel cloth‚ and fur cloth. The observations we have done brought

What determines the perceived brightness of objects? Luminance is a physical and objective measure of the intensity of light. The sensation elicited by different luminances is called brightness. However brightness is a subjective measure as it is the perceived amount of light emanating from an object. It may seem logical to expect that luminance and brightness are directly proportional and that two objects that reflect the same amount of physical light into the eye will look the same brightness

The reaction order‚ based on the rate law‚ was first order with respect to crystal violet and second order with respect to OH-. The rate law was as follows: Rate law = k [CV]1[OH-]1 where k equaled 2.61. In order to determine the reaction order with respect to crystal violet‚ the graph that described the relationship between ln[CV] and time (seconds) was Figure 2. Not only did Figure 2 generate a more linear relationship‚ but it had the highest R2 value of 0.992 than ([CV] versus time) and ([1/CV]

This indicates the presence of systematic error in the experiment. The experimental value for the molar mass of butane was 66 ±2 g/mol‚ with the literature value of 58.122 g/mol not lying within this uncertainty and a percentage error of about 13%. This indicates the presence of systematic error in this experiment too. A potential follow-up experiment could be to use an alternative gas to do the experiment‚ such as propane‚ or to alter the temperature of the gas to see
