This report shows a comparison between hydrogen fuel cell plug-in hybrid vehicles (FCHEV) and battery (BEV) and hydrogen fuel cell (FCEV) electric vehicles. Comparing infrastructure and technology requirements along with the lifecycle cost of the drivetrain (the main components that generate power and deliver it to the road surface) over 100k miles taking fuel costs and capital costs into consideration. This can then be compared to a conventional petrol-fuelled internal combustion engine (ICE) drivetrain
The purpose of this lab was to study some characteristics of enzyme action by investigating how the enzyme catalase decomposes hydrogen peroxide. It connects to our unit about enzymes because it illustrates how enzymes decompose their substrates and their rate of decomposition. In the graph of the more accurate experiment, it shows that the amount of product (in mL) gradually increased over time until at about 120 seconds. After that, it would just gradually begin to plateau meaning enzyme activity
Catalase and Hydrogen Peroxide Experiment How do living cells interface with the earth around them? Every living thing have impetuses, or substances inside of them that accelerate concoction responses and procedures. Proteins are atoms that empower the substance responses that happen in every single living thing on earth. In this catalase and hydrogen peroxide test, we will find how compounds go about as impetuses by bringing on synthetic responses to happen all the more rapidly inside of living
Kinetics of the Decomposition of Hydrogen Peroxide Lab Introduction: In this week’s lab experiment, the rate of decomposition of hydrogen peroxide forming oxygen gas will be observed and studied. Since the rate of a chemical reaction is dependent on two things; the concentrations of the reactants and the temperature at which the process is performed, the rate can be measured at which a reactant disappears or at which a product appears. When measuring the rate, the rate law will be applied. The
Introduction H2O2 is commonly known as hydrogen peroxide and it is a strong oxidizer and a naturally produced compound in humans as a by-product of oxidative metabolism. Because of this, humans also produce the enzyme catalase peroxidases in order to convert small amounts of H2O2 into oxygen and water. It uses the following chemical formula: 2H_2 O_2→O_2+〖2H〗_2 O This process is called decomposition as two hydrogen peroxide molecules are broken down into oxygen and two water molecules. Catalase is
PreLab Questions: The reaction that will be taking place is Catalase breaking down hydrogen peroxide. The enzyme in the reaction is Catalase. If another enzyme like lactase is used, no reaction would take place because the substrate, hydrogen peroxide, wouldn’t fit into the active site. The substrate is the hydrogen peroxide The product is H2O and O2. The rate of reaction will be measured by timing how long it takes for the spheres of yeast to sink and float up to the top again. Three factors that
Carbon information as possible from our Ibuprofen solution, we also used the two-dimensional NMR technique DEPT. DEPT creates three different C13-NMR spectra. Each DEPT provides specific details when it comes to determining how many specific Carbon-Hydrogen environments (CH3’s, CH2’s, and CH’s) exist in Ibuprofen. The DEPT-135 spectrum represents CH3 and CH Carbons as
materials used for rockets- shaping society and the environment of the modern world. The sheer range of applications where chemistry is involved inspires me to contribute, while learning, unlocking why everything behaves the way it does. With the hydrogen fusion project in construction and the recent use of hydraulic fracturing which has caused environmental and social dispute, I chose to undertake the extended project qualification related to this, energy, as chemistry leads these
Background The decomposition of Hydrogen Peroxide can be expressed in this chemical equation: 2H2O2 (l) -- 2H2O (l) + O2 (g). This process is commonly found in organism as it is a byproduct of metabolism. An accumulation of hydrogen peroxide is dangerous so as a result the body system developed a way to speed up this decomposition. Commonly called a catalyst, which speeds up the reaction. Catalysts may range from enzyme to inorganic catalysts. In this experiment this employ a heterogeneous catalysis
decline. Hydrogen is on its way to remove gasoline as the world’s fuel. Hydrogen powered cars are rising in popularity for many reasons such as low emissions and efficiency, but there are major obstacles in the way. Hydrogen as a fuel is the change needed to save the world from global warming. One of the leading contributors to the destruction of
