SAUDI ARABIA PRODUCES METHANOL IT WILL BE CHEAPER TO USE IT TO PRODUCE FORMALIN METHODS OF PRODUCTION Formaldehyde is known to be one of the most reactive organic compounds. It can be produced by various reactions. It can produced by methods such as: Methanol undergoes an oxidation reaction in the presence of catalysts, ethyl-alcohol, coal gas, ethylene, methane, glycol, glycerin, and carbon…

intermediate is formed in the rate determining step of a reaction and then goes to give products in low barrier. Also, the hydrocarbon reaction of terminal alkenes gives mixtures of primary and secondary boranes that formed in an exothermic biomolecular step. Carpenter, et al study outlined of reactive intermediate. They mentioned that the assumptions about the behavior reactive intermediate. The first one…

The purpose of this experiment was to determine the thermodynamic properties of the entropy, enthalpy and free energy, as well as the solubility product of borax as a function of temperature from the dissolution of borax in an aqueous solution. Thermodynamics is the study of heat and its transformations. The properties of thermodynamics are entropy, enthalpy and free energy. The properties of thermodynamics can be viewed in terms of spontaneity. Spontaneity is a spontaneous change of a system…

Introduction The reaction of Hydro Chloric Acid with Aluminum is exothermic and very dynamic. The Hydrogen produced at such temperatures can easily explode by combining with the oxygen of the atmosphere. This reaction is known as a single displacement reaction because aluminum switches with the hydrogen. When aluminum is placed in a beaker of hydrochloric acid, the reaction produces hydrogen gas and aqueous aluminum chloride. The balanced chemical equation for the reaction is 2Al + 6HCl =…

Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment…

pressure increases the concentration of gas molecules, which in turn speeds up the reaction (Brown, 2000). When the temperature is decreased the position of equilibrium is moved to the right, which also results in more ammonia with a higher yield, as heat is released in this equation this is a exothermic reaction (AUS-e-TUTE, 2014) this change of heat in a system is known as enthalpy. The reaction is exothermic as the reaction favors the low temperature. More ammonia gas is produced because the…

Discussion Enzymes are biological catalysts that help speed chemical reactions. In part A (table 2), it was seen that a normal reaction of catalase and hydrogen peroxide resulted in the release of bubbles (oxygen gas) and the release of energy in the form of heat which shows that the reaction was a exothermic reaction. The reaction was given a reaction rate of four and acted as the control with which we could compare the other results to. When testing whether or not catalase is reusable in part…

explore how different factors affect the reaction rate of enzymes reacting with their corresponding substrates in order to learn more about how enzymes function in different environments. The independent variables investigated in this experiment were the concentration of different substrates, the temperature of the environment, and the effect of a catalyst on the reaction rate. The dependent variable for all of the investigations was the time it took for the reaction to occur. To investigate…

This demonstration is called Elephant’s Toothpaste because the chemical reaction produces a large foamy mess that looks like toothpaste squirting out of a tube. We want to do this project because we want to show how this science experiment works and tell the reactions of it. How It Works: This large demonstration uses hydrogen peroxide, sodium iodide and soap. First, we pour in the hydrogen peroxide, then the soap and finally the sodium iodide. The yeast contains an enzyme called Catalase…

The simple reaction between two substances (Mg and HCL) was performed to determine how different factors such as, temperature, and concentration effects the rate of reaction. There were noticeable differences while determining the effects of concentration of HCL on the rate of reaction. Increasing in the concentration of the HCL, bottom of the test tube became hotter; it’s an exothermic reaction because energy is being released during the reaction in the form of heat. Another, increasing in…
