Stoichiometry Lab Report

514 Words3 Pages

In Chemistry, compounds are defined as any substance that is composed of atoms of two or more elements that are combined in fixed ratios. Compounds can often be reduced in order to separate their elements and study their properties. Compounds such as water (H2O) and Carbon Dioxide (CO2) for example, both contain oxygen and can therefore undergo a process of decomposition that will isolate the elements in order to calculate the quantity of each element and molecule present in the compound. Any compound with oxygen can be decomposed through the addition of heat which will eventually release the oxygen, thereby leaving only the other elements. Decomposition reactions are essentially chemical changes in which a single compound is broken down into two or more single products (Wilbraham, 2008). …show more content…

In order to measure the quantity of each molecule present, Stoichiometry was used to test the quantitative relationship between products and reactants in a chemical reaction (Graves, 2014). Stoichiometry is helpful because it uses amount of the starting reactant to estimate the amount of products formed and vice versa. The chemical equation must be balanced, meaning all of the atoms present in the reactants side must also be present in the products side (Burdge, 2014). By using the right quantities in a balanced chemical reaction, the amount of products desired can be determined as well as the quantities of the reactions using mole to mole and mole to mass ratios (Burdge, 2014). For example, using the chemical

    The chemical elements are divided into two broad groups, the metals and the non-metals. In this experiment, you will examine some members of the metal group and identify similarities and differences in their physical and chemical properties. Metals are the elements that are found in the left of the periodic table with high electrical and thermal conductivity. Metals lose electrons to create positive ion charges. Metals have a unique shine, are prone to forming, have a high tendency to form cations, and combine with oxygen to give mostly basic oxides.

    In order to begin this experiment, first one must find the balanced chemical equation for the reaction which occurs between the aluminum and copper (II) chloride. This balanced equation being 2Al(s)+3CuCl2 (aq)3Cu(s)+2AlCl3 (aq). After finding this equation, one must use the process of stoichiometry in order to find how many grams of aluminum are needed in order to produce 0.15 grams of copper. In this experiment, the purpose was to produce between 0.1 and 0.2 grams of copper, so one should attempt to produce 0.15 grams of copper seeing as it is the average of those two numbers. The first step in the stoichiometric process which one has to complete is finding how many grams of copper are in one mole of copper.

    A mixture of elements is what is known as compounds. Chemical reactions occur when particles react with each other and atoms in molecules get rearranged. Reactions happen either rapidly or slowly. The speed of a reaction is known as the rate of the reaction. This speed of chemical reaction depends on many factors such as temperature, particle size of reactants, and the intensity of reactants.

    The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

    The decomposition of NaHCO3 is an example of Prevention within Green Chemistry principles because all solid waste in this experiment is collected and used again. The only gaseous wastes generated by the reaction in the experiment are carbon dioxide and water, which are benign (Lab 3). The decomposition reaction of NaHCO3, generates virtually no waste, therefore less hazardous chemical syntheses. The byproducts of the reaction are gaseous CO2 and H2O which possess little or no toxicity to human health and the environment, because of the amounts released in this experiment. (Lab 3).

    INTRODUCTION A gas chromatograph (GC) can be utilized to analyze the contents of a sample quantitatively or in certain circumstances also qualitatively. In the case of preparative chromatography, a pure compound can be extracted from a mixture. The principle of gas chromatography can be explained as following: A micro syringe is used to inject a known volume of vaporous or liquid analyte into the head or entrance of a column whereby a stream of an inert gas acts a carrier (mobile phase). The column acts as a separator of individual or chemically similar components.

Background: Just like a recipe would call for a specific amount of one ingredient to a specific amount of another, stoichiometry is the same exact method for calculating moles in a chemical reaction. Sometimes, we may not have enough of or too much of one ingredient , which would be defined as limiting and excess reagent, respectively.

    Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has

In order to accurately digest the experiments results, research of definitions of each relating led 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 forms when two or more nonmetal atoms share valence electrons; covalent compounds are also

    This first quarter of Second semester in a new class has been very good because I have kept my notebook very organized and up to date. For example from the left side of my notebook on page 92, I annotated and highlighted important information for this activity. This work shows high quality because of the use of different color and the annotations about specific ideas that we would be learning from this packet. Using color and making annotations has made it easier for me to use conversions with stoichiometry. The Relative Mass and the Mole work taught me about how to find the ratios of two atoms, the molar mass of elements, and Avogadro’s number.
