Chemical Reactions Lab Synthesis Reactions: Synthesis reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general

BALANCE LAB Introduction The purpose of this lab is to become familiar with how to use the ChemLab program for determining mass using both the centigram balance and the electronic balance. Using the centigram balance‚ the mass‚ in grams‚ of a copper slug will be determined by both direct weighing and weighing by difference techniques. Using an electronic balance‚ the wight of a copper slug will be determined by also utilizing direct weighing and weighing by difference. Average mass of a

The purpose of this lab was in order to find which combination of two electrodes would produce the greatest voltage‚ under the condition that lemon juice was the electrolyte within a chemical cell. To conduct the lab‚ two slits were created in a lemon‚ which worked as a chemical cell‚ and an assortment of different electrodes were inserted into the lemon. Afterward‚ two wires were attached to each of the electrodes‚ where a voltmeter then gave a reading that was recorded into data. As the experiment

Chemistry 1411- 106 Pre Lab Experiment #8 Objective: This Lab will help us to understand oxidation reduction and double displacement through finding the percent composition of pennies. We will also once again be working with titration in this lab. We will titrate the solution until we are only left with a solid form which will tell us about the composition of pennies. Introduction: The weight of a post 1982 penny is 2.5 grams‚ and the percent of zinc is 97.5% leaving only 2.5% copper. The amount of Zinc

Timothy Johns Christian Howard Wan Huang 10/18/12 Flame Test Lab Introduction Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by atoms and molecules. These studies are very helpful in determining an unknown element‚ given the fact that all elements burn a different color. The flame colors vary because of the different amounts of energy the elements give off. This lab is made for the learner to determine the identity of two unknown elements. Hypothesis If

electrolysis is carried out then write balanced half reactions and compare to observations. Part A/B- Aquire a U-tube with flexible tubing at bottom‚ and close tightly with a clamp to add different cells before mixing. Prepare metal strips of lead‚ copper‚ zinc‚ and iron as electrodes by cleaning them with steel wool. Fill each side of you tube with proper cell and electrode for each test and record cell potential with a voltmeter. Part C – Use an all glass U tube and various cell solutions to be

comparing the density of Zn(zinc) and Cu(copper)‚ you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v. Materials: * 2 metals (options: zn‚ al‚ or cu) * 3 samples of each metal (small‚ medium‚ and large) * Scale/Balance * Calculator * Water * Graduated Cylinder Safety: * Be prepared for your work in the laboratory. * Read all procedures thoroughly before entering the lab and/or starting experiment. * Be alert
