Stoichiometry

spectrum of the product in liquid suspension was measured (see attached spectrum), as well as the product’s melting point range and the percent yield of the reaction (The limiting reagent and theoretical yield were determined using the reaction stoichiometry). Melting Point Range Trial 1: 30.3C…

The problem of the experiment was to determine the volume of one mole of H_(2(g)) at STP. In a way, the problem is essential in understanding how one mole of an ideal gas at STP is always equivalent to 22.4 L. By determining if the volume of a mole of H_(2(g)) is 22.4 L, it supports Avogadro’s law that one mole of an ideal gas occupies 22.4 L at STP. At the same time, it indicates that a direct relationship exists between volume and the number of moles of gas as temperature and pressure stays…

1.1 Overview of aerospace industry Globally, 3.57 billion passengers travelled on aeroplanes during 2015 and the demand for air travel is predicted to keep rising.1 As the frequency of air travel is increasing, it places a pressure on the aerospace industry to improve material performance and the efficiency of their transportation.2 Classically aircraft were constructed from metallic materials such as aluminium and titanium. Therefore, new materials must have specific properties and…

1. Introduction and background The experiment that will be conducted is the preparation of benzoic acid. Benzoic acid is a carboxylic acid and this has been established in the 16th century. The molecular structure of benzoic acid can be seen in the following figure. Figure 1 – Molecular Structure Benzoic acid is used to prepare esters with the very high boiling points and is used as plasticisers. Plasticisers are compounds that are added to plastics to…

Introduction As humans are unable to produce Vitamin C (ascorbic acid) but still require it for proper body function, humans obtain Vitamin C from external sources.1 Historically, citrus fruits, which have a comparatively higher amount of Vitamin C, were eaten to achieve proper amounts of Vitamin C or prevent scurvy. During the age of long sea voyages, where fresh food was scarce, scurvy was prevalent and extremely detrimental .2 However, fruit was not always available or economically feasible.…

Abstract: The purpose of this experiment was to prepare and standardize a sodium hydroxide solution as well as determine the molar concentration in as strong acid and the percent by mass of acetic acid in vinegar. We used volumetric analysis, also known as titration, in both experiments. The average molar concentration for NaOH was 0.2749 mol/L while the average molar concentration of the acid solution was .2493 mol/L.The average percent by mass of acetic acid in vinegar was found to be 12.3 %…

qualitative tests for these substances. For the second week of the lab, the there were three objectives that related to the procedure: to determine the calcium concentration of milk using the technique of titration, to us the concepts of molarity and stoichiometry to perform a quantitative analysis of metal ions found in samples, and to understand and work with other concentration units like ppm. INTRODUCTION Within the lab experiment, qualitative tests were conducted to determine the presence…

Rocket Lab Experiment #4 Lilly Creswick (w/ Michelle Kubrin) Colorado School of Mines Chemistry 121 section 2AB Tace Rand Dr. Caster, Dr. Falconer, Dr. Sower September 20, 2016 Abstract: The Rocket Lab aimed to create a successful rocket made out of a pipet bulb filled with Acetylene and Oxygen gas. Different ratios of Oxygen and Acetylene gas were used to determine what would create the largest propulsion and launch the rocket bulb the furthest. A pipet bulb was used as the…

Multiple mechanisms are taken place in different types of plants to maintain the efficacy of photosynthesis. Plants fall within three categories: C3 plants, C4 plants, or CAM plants. C3 plants are the most common type of plant, C4 plants consist of mainly tropical plants, and CAM plants are succulents, such as cacti, which are found in arid and hot environments, such as the deserts. Each one of these plants have a specific enzyme in which it binds atmospheric carbon dioxide, with high affinity,…

Experimental Design Aim 1: Determine the amino acid sensing specificity of folliculin. Since folliculin’s novel amino acid sensing function discovery, I plan to further understand whether FLCN specifically senses a certain amino acid and if this level of detection is enough to elicit an mTORC1 response. 1.1. Determine if folliculin’s novel molecular function in amino acid sensing is triggered by glutamine. mTORC1 activation by amino acids requires FLCN where its lysosomal residence during…
