study a set of metals and their reactions reactions using different metals in an ordered activity series‚ the goal is to find the relative reactivity of them.Discovering why metals react with certain cations and solutions is the main point of this lab. This has many real life applications. When creating buildings‚ or bridges it is important to understand and counter-act the rusting of iron. You can do that by using the activity series. For any industry using metals‚ this is important. Manufacturing

Mass of Copper in a Penny Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies. The composition of a standard penny is 97.5% Zn and 2.5% Cu. In the lab we will be using Beer’s Law (A=elc+b where A is solution absorbance‚ e is a constant called molar absorbency‚ l is the length in cm‚ and c is the concentration). Using Beer’s Law in this lab a colorimeter

One of his painting‚ Fritillaries in a Copper Vase‚ especially stood out to me choreographically. The way in the flowers laid downward reminded me of hands potentially

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

In this lab‚ there was a comparison between accuracy and precision of densities measured by volume. Mass measurements are often used units in the metric system. Volume can be examined a borrowed unit. The volume measurements were made in mL. Every measurement had a level of hesitancy affiliated with it. The experiment could feel uncertain from the object used for measurement and from the accuracy of the person doing the measuring of the volume. Because of this uncertainty‚ the experiment must be

in food and different amounts of energy released when consumed. Throughout this experiment our procedure was to take different food samples and use a device known as a calorimeter made from a can of aluminum‚ one large paper clips and a string of copper wire to measure the amount of thermal energy released during a reaction. By measuring the temperature difference before and after a reaction‚ the calorimeter indicates how much energy is released. From personal experiences I had previously learned
