Abstract: This experiment was all about observing a chemical reaction. During the experiment‚ we made observations and possible explanations on why Copper(II)Chloride Dehydrate and Aluminum foil created a chemical reaction. The observations were made by using Copper Chloride‚ Aluminum foil‚ and Distilled water. Before the Aluminum was added into the Copper Chloride was turquoise. As we added the Aluminum the color changed to green and the water boiled. So we met the purpose of this lab. Purpose:

determine the limiting reactant of a chemical reaction that involves iron filings and a copper sulfate solution. Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method used to perform this lab will be to combine a metal with

the biotic environment that it comes in contact with as well as the non-living matter in the area. In the following experiment‚ the student will use a variation of nitric acid solutions with different molarities to see the effects that they have on copper. For the control‚ the same tests will be done with rainwater with a known pH. After the experiment the concentration of the solutions can be converted to pH using the equation pH = -log[H+]. After converting this the student will show a display of

STATEMENT OF THE PROBLEM Main Problem: How can the ionization chamber detect if the environment is surrounded or has Radon? Sub- Problems: What are the primary sources of radon gas? What elements are found when radon decays? How can this gas cause different kinds of diseases? OBJECTIVE: Build a simple ionization chamber that is capable of detecting fairly low levels of radiation BACKGROUND OF THE STUDY Radon is a cancer-causing gas. It comes from the natural breakdown of uranium in soil

Measurement of Mass and Volume Part A: The Formula of Hydrated Copper (II) Sulfate Aim: The objective of this experiment is to find out the accurate mass of a solid and to calculate the moles of an unknown. Materials: The materials used in this experiment are Hydrated Copper (II) Sulfate‚ weighing bottle‚ analytical balance‚ laboratory balance‚ casserole‚ spatula‚ and hotplate. Methods: First‚ approximate 1.0g of hydrated copper (II) sulfate was transferred into a weighing bottle and the

Reactions of Copper Objective The objective of this lab is to convert copper (Cu0) “in a series of reactions to various compound containing copper as the Cu2+ species” (CHM111 Laboratory Manual) in order to prove the Law of the Conservation of Mass. Introduction In this experiment‚ we took a look at how copper (Cu0) reacts with different substances to get an end result where it is transformed back to its original state. There were five different reactions that involved copper. We first experimented

Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double displacement of compounds or elements

experiment you will investigate the reaction of copper metal with oxygen in the air. Using stoichiometry‚ you can predict the amount of copper oxide (CuO) that could be produced if all the copper would react. However‚ when you perform the reaction yourself‚ you will discover that only some of the copper reacts to form black copper oxide. A stoichiometric calculation will allow you to determine the amount of copper oxide produced and the amount of unreacted copper remaining. In the second part of the experiment

The human body has a complex homeostatic mechanism that lets us supply copper‚ while eliminating excess copper whenever this occurs. The dietary standards for copper have been set by various health agencies around the world. Standards adopted by some nations recommend different copper intake levels for adults‚ pregnant

solution Copper (II) chloride is blue in color‚ and when the aluminum sulfide was placed in‚ the solution began to burn and the CuCl2 began to work at the aluminum‚ turning it into a dark brown color of porous material. The reaction was exothermic‚ which is when a reaction releases heat. The way to determine this if the test tube felt hot after the heat was released‚ since it elevates the temperature of the mixture. The reactants were Copper (II) chloride and Aluminum‚ which produced Copper metal and
