Hydrogen sulfide

runs into the problem with maintaining soil moisture. Within the Hab there is not enough water to sustain both Watney and his plants. Watney devises a plan to use rocket fuel and the martian atmosphere to produce hydrogen and oxygen gas. He then plans to controllably ignite the hydrogen and oxygen gas to form water (Weir 26).…

The color a flame turns when burning a chemical compound depends on the metal ions the compound’s elements contain. What causes color to be shown is the excitement of electrons in an atom when heated, which makes them jump to a higher energy level. As the electrons begin to return to their original energy level, energy is released as light, coloring the flame (“Flame Tests”, 2005). And as energy increases, frequency increases, but wavelength decreases. The color each chemical turns the flame…

on each side must be balanced, meaning that nothing is destroyed or created in the reaction. On pg 72 of the interactive notebook, there is a diagram of a chemical reaction showing a reaction between carbon, hydrogen, and oxygen. On the reactant side of the reaction there is 1 carbon, 4 hydrogen, and 4 oxygen. On the product side, although it looks much different, there is still the exact same amount of each, meaning that it created something new (a chemical reaction), but stayed balanced. Also…

placed on the right near the noble gas neon. B is for… Bonds Fluorine can bond with almost every element! It can create an ionic bond by bonding with another element such as sodium to create NaF. It can also use covalent bonds when bonding. Hydrogen…

Introduction The goal of this experiment was to determine atomic weight of Kandimonium and the relative number of M&M’s in Kandimonium. Kandimonim is composed of three isotopes: Skittles, M&M’s, and Sweet Tarts, and the ratio of Sweet Tarts to Skittles is 27:18. The relative number of M&M’s and the atomic mass were determined by weighing each of the different Isotopes and calculating their average masses for further calculations. Calculations The following calculations were used to…

Hydrazine (N2H4) is a colorless, oily liquid that has an odor similar to ammonia. Other names for Hydrazine include Diamine, Nitrogen hydride, Diazine, and Levoxine. Its molecular weight is 32.05 g/mol and it is miscible in water. Its boiling point is 113.5 degrees Celsius at 760 mm Hg and its melting point is 2.0 degrees Celsius. Most people can smell hydrazine when present at concentrations of 2.0–8.0 parts per million (Choudhary G). “It is known for its corrosive and strong reducing…

To prevent rust or oxidation, most macromolecules essential for human existence are shielded from molecular oxygen or oxygen equivalents with hydrogen molecules (reduction). Oxygen equivalents are those compounds that remove these protective hydrogen molecules from other compounds. They are also called oxidizing agents. Compounds that restore these hydrogen molecules are called reducing…

Luminol is used to reveal traces of blood in crime scenes, using a light producing chemical reaction, between many chemicals, and hemoglobin. It is a powdery compound made up of carbon, hydrogen, nitrogen, and oxygen. Mixing C8H7N3O2 (luminol) with H2O2 (hydrogen peroxide), causes it to become a liquid. Hydrogen peroxide and luminol are the two main parts of this chemical reaction. To produce a strong glow, a catalyst needs to be present. A catalyst is a substance that increases the rate of a…

Stoichiometry is known as the quantitative relationship between various products and reactants in a chemical reaction. There are many ways one can stoichiometry in his/her advantage. If you start off with a known amount of reactant, stoichiometry can definitely be used to make a prediction to the amounts of the future product that will be formed. And in the other side, if you has a desired amount of product want, you can use stoichiometry to predict of on how much reactant you will need to…

In this experiment, the competing enantioselective conversion (CEC) method was used to react an unknown secondary alcohol, which is either the R- or the S- enantiomer, with S-HBTM and R-HBTM separately. Thin-layer chromatography (TLC) was used to determine which reaction was faster. If the S-HBTM was faster, then the unknown secondary alcohol had the R configuration. If the R-HBTM was faster, then the unknown secondary alcohol had the S configuration. 1H NMR was used to determine the molecular…
