  • Empirical Formula For Ag5o2

    431 Words  | 2 Pages

    The empirical formula for silver oxide for trial one is Ag5O4 and for trial two is Ag3O2. For trial one there is 0.451 grams of silver were produced from 0.504 grams of silver oxide. For trial two there is 0.456 grams of silver were produced from 0.500 grams of silver oxide. The difference between the mass of silver oxide and mass of silver is the mass of oxygen that vaporized into the air. There are 0.053 grams of oxygen vaporized into the air for trial one and 0.456 grams’ oxygen for trial two

    Empirical Formula Lab Report The purpose of this lab was to determine the empirical formula of copper oxide compound. In the lab, hydrochloric acid and copper oxide compound was mixed until it formed a blue solution. An oxidation-reduction reaction, a reaction in which there is an exchange of electrons between elements, was performed by adding zinc to the solution to displace the copper in copper chloride. Zinc, in this case, was oxidized by losing two electrons (0 → 2+) while copper was reduced

  • Zinc And Chlorine Empirical Formula

    539 Words  | 3 Pages

    The answer to the question of “What is the empirical formula of this substance containing zinc and chlorine?” Simply put, the answer is ZnCl2. This is what the empirical formula is because when the mass of each substance is converted into number of atoms, the ratio of Zinc to Chlorine is about 2:1 for almost every trial conducted. See Figure 1. Equations 1 and 2 demonstrate how the conversions were performed and how moles/ molecular weights of each substance were incorporated in the calculations

  • Empirical Formula of Zinc Iodide

    Experiment 9 Empirical Formula of Zinc Iodide Objectives Upon completion of this experiment, students should have learned: 1. The law of conservation of mass. 2. How to calculate an empirical formula. 3. The concept of limiting reagents. Introduction Synthesis and the determination of empirical formulas are two extremely important parts of chemistry. In this experiment, you will synthesize zinc iodide and determine its empirical formula. The molecular formula gives the actual

  • The Empirical Formula Of Magnesium Oxide

    1359 Words  | 6 Pages

    this lab was to find the empirical formula of magnesium oxide. In order to produce magnesium oxide. In this experiment, magnesium reacted in an oxygen-rich environment while inside of a crucible. The masses before and after the oxidation were both measured. The masses that were resulted were then used to calculate the empirical formula of magnesium oxide. The simplest whole-number in the form of a ratio in which atoms join and form a compound is known as the empirical formula. By finding the percent

  • Explain The Empirical Formula Of Magnesium Oxide

    Report Purpose: In this experiment we combined magnesium metal with oxygen in air by heating. We used the measured mass of magnesium metal and magnesium oxide to determine the empirical formula of the oxide product. We had to find the experimental percent composition (by mass) of MgO, come up with the experimental empirical formula of magnesium oxide, and balance the chemical equation: Mg (s) + O2 (g) → MgxOy (s). Materials and Safety: Bunsen Burner Ring Stand Metal Ring Clay Triangle Crucible and

    we learned before on how to determine the empirical formula of a compound based on the test and also chemical analysis on it. Hence this experiment is mainly goes around with how to determine the empirical formula of Magnesium Oxide following various tight procedures in order to get the knowledge and apply it onto another compounds. We are investigating the empirical formula of Magnesium Oxide in this experiment. RESEARCH QUESTION: How empirical formula of Magnesium Oxide is obtained by heating

  • Summary Of The Empirical Formula Of Magnesium Sulfate Hydrate

    700 Words  | 3 Pages

    The goal of this lab was to find the empirical formula of Magnesium sulfate hydrate. To determine this formula, we measured and recorded the mass of an empty clay crucible. We then poured a small amount of Epsom salt into the crucible, and then recorded the mass of the filled crucible. We then subtracted the weight of the empty crucible from the weight of the crucible with Epsom salt to determine the mass of the Epsom salt. We then lit a bunsen burner, and manipulated the airflow to allow for the
