Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was

AP Chemistry Unit 2 Notes Stoichiometry You should understand all that is presented in chapter 3 of your text (Zumdahl: Chemistry‚ 8th edition). Some of the highlights are presented below. Atomic Masses (Section 3.1) Nearly every element is made up of atoms of more than one isotope for that element. A few‚ like Be‚ only have one isotope. Others can have a large number of isotopes. Tin (Sn) has ten isotopes. (No pun intended.) Isotopic abundance is determined by the use of

Purpose=The purpose of this lab was to combine reactants‚ which we would pick ourself‚ to make 2 grams of Copper Phosphate and another product. Background: Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. Chemistry has to do with many things we use today. For example‚ fireworks are made by the chemical combining magnesium‚ titanium‚ copper‚ aluminum‚ strontium‚ or other periodical elements. Things also like making plastic‚ jewelry‚ coins

Stoichiometry lab By: James Stewart Purpose: To calculate mole ratios Introduction: There are two types of chemical analysis; qualitative analysis which is the identification of a substance present in a material‚ and qualitative analysis which measures the amount of the substance. In this lab‚ you will perform a quantitative analysis of a two-step reaction. Copper(II) oxide will be synthesized from a known mass of copper(II) sulfate pentahydrate. Using the relationship of the balanced equation

silicate‚ artisans also helped with the discovery of a bright yellow made from lead and antimony oxides‚ the vinegar fumes used to corrode lead and copper into lead white 2PbCO3•Pb(OH)2‚ and green also known as verdigris copper(II) acetate. The red color known as vermillion demonstrated an important cross between are and chemistry in color. Vermilion is made up of mercury sulfide‚ which has been used as a pigment since roman times. Chemists discovered that by making the compound by purposefully combining

experimental research‚ the percent oxygen of potassium chlorate can be determined using tactics such as stoichiometry‚ a technique used to determine the amount of substances that are in a reaction. Stoichiometry is an efficient way to determine how much of a certain substance is within a certain compound‚ which is used in many practical ways‚ such as pharmaceutical companies using stoichiometry to determine how much of a particular chemical is needed to use within a drug. However‚ within certain gas

out 1.0 g of CaCl2·2H2O and put it into the 100-mL beaker. Add 25 mL of distilled water and stir to form the calcium chloride solution. Use only distilled water since tap water may have impurities that interfere with the experiment. 3. Use stoichiometry to determine how much Na2CO3 you will need for a full reaction. 4. Weigh the calculated amount of Na2CO3 and put it in a small paper cup. Add 25 mL of distilled water and stir to make a sodium carbonate solution. 5. Pour the sodium carbonate
