Stoichiometry Lab Report

418 Words2 Pages

Lab 27. Stoichiometry and Chemical Reactions Report In our lab we were asked Which Balanced Chemical Equation Best Represents the Thermal Decomposition of Sodium Bicarbonate. Sodium Bicarbonate is a chemical compound with the formula NaHCO3, also known as baking soda. In the process to answer our guiding question we have to determine how atoms are rearranged during a chemical reaction. That is where stoichiometry comes along, which is the quantitative relationships or ratios between two or more substances undergoing a physical or chemical change in a balanced equation. It identifies the mole ratio between reactants and products. To understand stoichiometry you have to understand the products and reactants, which involves how to solve balanced reactions. This allows chemists to determine how many moles of a product will be produced from a specific number of moles of a recant or how many moles of reactant are needed to produce a specific amount of a product. …show more content…

First, you place the bunsen burner on the ring stand and tightly place the metal ring and place the clay triangle on it. Before placing the crucible on the ring you must put baking soda in the crucible, and place it on the ring stand. Then with safety precautions light the bunsen burner with the matches provided. In our first experiment we first started with 1.04 grams of NaHCO3 and ended with .60 g Na2CO3. In the second experiment we started with 3.2 g NaHCO3 and had a result of 2.0 grams

In the lab, the theoretical yield of CO2 was calculated by using the mass of the Alka-Seltzer (in Part A) and the mass of the anti-acid (Part B) were multiplied by the mole ratios that were involved in the reaction equation for each reaction and they were also divided by the molar mass of each substance. From the balanced chemical equations that were included in the calculation portion, the limiting reactant in part A was determined to be citric acid. The limiting reactant in part B was determined to be HCl because in the reaction, the HCl would ran out before the calcium carbonate. The stoichiometry would not have been different when converting between the different states of matter because the state is a measure of kinetic energy, and not

Students first prepped for the lab by cleaning out the crucible. Three boiling chips were added in the crucible once it was wiped out with a paper towel. The crucible was then placed on a clay triangle two finger widths above the Fischer burner. After 10 minutes of the crucible being directly under the flame, the it was clean and students allowed time for it to cool down. Next, the students from then on used tongs to transport the crucible from weighing it and back to the clay triangle.

Stoichiometry is a method used in chemistry that involves using relationships between reactants and products in a chemical reaction, to determine a desired quantitative data. The purpose of the lab was to devise a method to determine the percent composition of NaHCO3 in an unknown mixture of compounds NaHCO3 and Na2CO. Heating the mixture of these two compounds will cause a decomposition reaction. Solid NaHCO3 chemically decomposes into gaseous carbon dioxide and water, via the following reaction: 2NaHCO3(s) Na2CO3(s) + H2O(g) + CO2(g). The decomposition reaction was performed in a crucible and heated with a Bunsen burner.

The wax melted first, followed by the salt, and lastly the sugar. The salt not only burned before the sugar, but developed a brown color throughout most of the substance at a faster pace. In the water solubility test, the salt dissolved in the water, as soon as it was properly mixed and the sugar dissolved in the water as well, but was stirred for a longer period of time until it was completely dissolved. The wax did not dissolve in the water, however bits of the substance broke off from the main piece. With this information, the final results included: wax as a nonpolar covalent compound, since the substance melted first and was not soluble in water; salt as a polar covalent compound, since the substance was soluble in water and the second to melt; and sugar as an ionic compound because the substance melted last and was soluble in

Lab Report For The Concentration Of Unknown Acid

1271 Words | 6 Pages

Introduction How do you find the concentration of an unknown acid? The law of conservation of mass will be observed in this lab because in a balanced or neutralized equation the number of moles of the acid is equal to the number of moles of the base. An equation that will be observed is that when an acid and a base are combined in a reaction they will produce salt and water. In order to properly conduct this lab procedure many different properties of acids and bases need to be understood. Acids have a pH lower than seven, turn litmus paper red, and when mixed with phenolphthalein remain colorless.

Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, definitions of each relating factor were researched, leading to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound is formed when two or more nonmetal atoms share valence electrons; covalent compounds are also categorized into two sections: polar covalent and nonpolar covalent. Furthermore, polar covalent compounds dissolve in water, while nonpolar covalent compounds do not.
