The purpose of this week’s lab is to learn to demonstrate a double-replacement reaction of ionic compounds. To accomplish this, two ionic compounds will be mixed together and the product will precipitate out of solution. In this procedure, the product must be precipitated out of the solution and then weighed.…
2. When first learning to balance equations, we learned that the number of atoms of each element in the products and reactants must be equivalent. What are some additional factors that must be…
8. Write balanced net ionic equations for each of the halogen reactions that occurred during this experiment.…
A. Write a one-paragraph analysis of the results for the procedure. Provide reasons for the difference in the rate of diffusion at the different temperatures.…

The purpose of this experiment was to study the different types of chemical reactions using physical and chemical properties and balanced chemical equations. There are four different types of chemical reactions decomposition reactions, single displacement reactions, synthesis reactions, and double displacement reactions.…
Background: Before completing this experiment, one must know about chemical formulas, ionic bonding, solutions and moles to understand the results of this experiment. A chemical formula is the symbol for compounds and elements. It tells chemists how many atoms are in a chemical compound, formula unit or molecular compound. In a chemical formula a subscript indicates how many atoms there are of an element before it. The coefficient in a chemical formula indicates how many molecules of the formula unit, or chemical compound. The chemical formulas we use in this experiment are NaCl (sodium chloride/salt), KCl (potassium chloride), and CsCl (cesium chloride) and CaCl2 (calcium chloride). To form…
Observe and record the results. For Diffusing part, place a small beaker of water in a place where it will not be disturbed. Then drop one small crystal of potassium permanganate into the beaker and record the appearance. For Recrystallization part, place approximately 5-7 grams of sodium thiosulfate in a test tube and heat the mixture the solid appears to melt. Then allow the solution to cool to room temperature. If no crystals appear when the test tube is cooled, the solution is supersaturated. Next drop one crystal of sodium thiosulfate into the supersaturated solution and describe what happens on the data sheet. The Dialysis section is divided into two parts: test for copper(II) ion and test for starch. For Test for Copper(II) ion part, take 1 mL of the water from the dialysis beaker and place it in a test tube, and then add a few drops of concentrated ammonium hydroxide and record the observations. Lastly, for Test for Starch section, take 1 mL of the water from the dialysis beaker and place it in a test tube. Add a few drops of iodine solution and record…

-This method can be used to solve systems of linear equations involving two or more variables. However, the system must be changed to an augmented matrix. -This method can also be used to find the inverse of a 2x2 matrix or larger matrices, 3x3, 4x4 etc. Note: The matrix must be a square matrix in order to find its inverse. An Augmented Matrix is used to solve a system of linear equations. a1 x + b1 y + c1 z = d1 a 2 x + b2 y + c 2 z = d 2 a3 x + b3 y + c3 z = d 3…
