Classifying Chemical Reactions

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.
Apparatus:
• Bunsen or lab burner -Test tube clamp
• Butane safety lighter - Test tube rack
• Evaporating dish - Wash bottle
• Forceps or crucible tongs - Wood Splints
• Heat resistant pad
• Litmus paper
• Pipets
• Spatula
• Test tubes
Materials:
 Ammonium carbonate, 0.5g
 Calcium carbonate, 0.5g
 Copper chloride solution, 4mL
 Hydrochloric acid, 4mL
 Magnesium ribbon, 2-4 cm strips
 Phenolphthalein indicator, 1 drop
 Sodium hydroxide solution, 1mL
 Sodium phosphate solution, 1mL
 Water
 Zinc, mossy, or zinc shot, 1-2 pieces
Introduction: In this lab we will classify different chemical reactions. Classifying chemical reactions allows us to predict what chemical reactions will occur when different substances are mixed.
Procedures:
Reaction 1)
1. Obtain a 3-4 cm strip of magnesium metal ribbon. Hold the piece of magnesium with forceps or crucible tongs and heat the metal in a lab burner flame.
2. When the magnesium ignites, remove it from the flame and hild it over an evaporating dish or a Pyrex watch glass until the metal has burned completely. Let the product fall into the evaporating dish.
3. Turn off the lab burner and observe the properties of the product in the evaporating dish.
4. Record observations in the data table.
Reaction 2)
5. Using a beral-type pipet, add about 2mL of 1 M hydrochloric acid solution to a small test tube.
6. Obtain a 2-3 cm strip of magnesium metal ribbon and coil it loosely into a small ball. Add the magnesium metal to the acid in the test tube.
7. Carefully feel the sides of the test tube and observe the resulting chemical reaction for about 30 seconds.
8. While the reaction is still occurring, light a wood splint and quickly place the burning splint in the mouth of the

    Introduction What is chemical change? Chemical change is the alteration of a substance into one or more different substances with different properties (also called chemical reaction). The four different types of chemial reations are synthesis, decomposition, single displacement, and double displacement. Synthesis is when atoms and/or molecules combine to form larger molecules. Decomposition is when a large molecules are split into elements or smaller molecules. Single Displacement has an element…

    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…

    This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is…

    The Sequence of Chemical Reactions Drew Selfridge Dave Allen, Lab partner Instructor Yang February 11, 1997 INTRODUCTION This experiment was to recover the most amount of copper after it is subjected to a sequence of reactions. The copper is originally in solid form, but the reactions will turn it into free Cu+2 ions floating in solution. The ions will then be regrouped to form solid copper once again. During this process, however, some of the Cu+2 ions may be lost. The copper will subjected…

    determine whether or not a chemical reaction occurred after the mixing of various chemicals. The evolution of a gas, the formation of precipitation, and the change of temperature or color are all indicative of a chemical reaction. It was assumed that a reaction did not take place if the mixture of chemicals exhibited none of these characteristics. Several precipitation, complex-ion formation, redox, and acid-base reactions were performed. Redox: Decomposition Reactions In a 13 x 100 mm test tube…

    Introduction The reaction rate of a chemical reaction is determined as the change in the concentration of a reactant or product over the change in time. [1] The rate of a reaction is determined by experiment. Many factors influence the rate of a reaction: the nature of the reaction, concentration, pressure, temperature, and surface area, presence of catalyst and intensity of light. [2] For a chemical reaction, the rate law or rate equation is a mathematical expressed equation that links the reaction rate with…
