Fluorine and oxygen are known to be the strongest oxidizers because they rip electrons off of other elements. After they take the electrons, they become ions left column which are quite inactive.
Monday February 8th Introduction to Chemical Reactions A single replacement reaction is a type of reaction where the more reactive metal replaces the less reactive metal dissolved in the solution.
You will carry out this reaction in the following lab. Copper and Aluminum Lab 1. Obtain a plastic cup.
Add 50 mL of water. Stir with a straw. Add a small piece of flat aluminum foil. When you get bored, add more Aluminum.
When nothing is happening, keep adding aluminum and stirring. Repeat until the aluminum fails to react. Add 10 mL of Ammonia and observe what happens. Prepare a control solution of 2 g Copper Chloride in 50 mL of water. Add 10 mL of ammonia and observe what happens.
Write a paragraph on your observations in this lab. When we added more foil and stirred, the chemical reaction slowed. When we added the ammonia, it turned the substance yellowish brown and to my knowledge stopped the reaction completely.
What eventually happens when you put the Aluminum in the Copper Chloride? The Aluminum looks like it is rusting at a fast pace, the shiny silver is turning to a copper color. What happens when ammonia is added to the Aluminum and Copper Chloride solution? In my observations, when the ammonia was added, the only thing that happened was the water turned more of a greenish yellow color.
What happens during the control reaction? The copper chloride, a green grain like substance, is mixed with water and it turns it blue and completely disolves. Is the reaction exothermic or endothermic?
This was an exothermic reaction because it caused heat Aluminum reacts with copper II chloride, CuCl2, to form copper metal and aluminum chloride, AlCl3. Identify the reactants and the products for the experiment. The reactants of this experiment were CuCl2 and Al.
The products of this experiment were AlCl3 and Cu. Write a word equation for the reaction based in the above statement. Write the equation using formulas for the reactants and products. We will balance this equation in class.EXPERIMENT 11 (2 Weeks)!!!!!Chemistry Laboratory TYPES OF CHEMICAL REACTIONS PART I INTRODUCTION Looking at the observation (no reaction) for the mixing of sodium chloride + aluminum nitrate reveals that both products, sodium nitrate and aluminum chloride are soluble.
Therefore, the. 1: Bing J. (). Uncoupling pollinator attraction and post-pollination mate selection in Nicotiana attenuata.
Talk presented at . identifying them in an unknown solution. The method is termed qualitative analysis. to add the reagent until you no longer observe precipitation.
You may have to repeat this Anions have specific reactions and you will learn these by doing some chemical reactions with solutions . Chemical or Physical Reaction?1 • Understand and be able to identify the difference between a chemical and physical change • Practice lab safety.
Materials (per group ~2 students): then will add sodium bicarbonate solution to observe a second color change. Chemical or Physical Reaction? 4. Resource Type: Virtual Labs. The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry.
