The purpose of the laboratory experiment was to observe the qualitative aspects of a copper reactions series. The lab report was required to include a purpose, procedure, data/observations, all reactions and side reactions written out with qualitative data beneath each product and reactant except H2O, and a summary. The procedure involved measuring about a leg […]

The constant equilibrium constant K, which is a function of the partial pressures in atmospheres, remains constant regardless of the initial composition, container volume, or total pressure of a gaseous chemical system. An equilibrium constant expression must be written for every gaseous chemical system and specifies the conditions required to attain equilibrium, where partial pressures […]

The question asks us to determine DE, given information about q and w. Plan We first determine the signs of q and w (Table 5. 1) and then use Equation 5. , DE = q + w, to calculate DE. Chemistry, The Central Science, 12th Edition Theodore L. Brown; H. Eugene Lemma,Jar. ; Bruce E. […]

Phenolphthalein is another acid-base indicator. What color do you observe? (General College Chemistry, 2014, up. 17-18). G. HCI and phenolphthalein. What color do you observe? When reacting phenolphthalein with an acid what color change do you expect? What color change do you expect with a base? (General College Chemistry, 2014, up. 17-18). H. Noah and […]

The Chemistry of Fireworks BY craggy A firework is an incendiary device or material that can be used forestalling reinstatement. There are chemicals located in the nose of the rocket that explode, producing the colors seen. The art of fireworks, first originated in ancient China, with thefts explosive being made from a mixture of black […]

In order to create the sodium hydroxide solution, its pellet-form was dissolved in deionized water. The concentration of ethanol varied in each trial, with 25 mol% and 35 mol% concentrations used in the reactor. In order to determine the rate constant, 10 ml samples were taken every 10 minutes for an hour during the reaction […]

Properties of Gases Purpose: The purpose of this lab is to investigate some physical and chemical properties of gases and to use these properties to identify these gases when they are encountered. Hypothesis: This experiment was for observational purposes to learn about the physical and chemical properties of gases, no hypothesis was required In order […]

During the carbon dioxide experiment, the bubbled gas rapidly changed colors, resulting in a slight green color. When adding Alka Seltzer to the test tube, there was lots of pressure, causing a color change in limewater from clear to nearly milky and rapid small bubbles. In the 3reath experiment, large bubbles occurred along with a […]

Abstract The Wittig Reaction is a nucleophilic addition in which an alkene is formed as a product. Both the E and Z isomers of the alkene result. Substituents on the aromatic aldehyde affect the E/Z ratio of products that form. In this experiment, a nitro group was used as the substituent in the ortho, meta […]

It is believed that the positively charged chlorine (Cl+) originated from the heterolytic bond cleavage of chlorine during the first step of the hypochlorite oxidation reaction mechanism, which converted endo-borneol to camphor. The initial step involved the replacement of a hydroxyl proton with positively charged chlorine, followed by an E2 elimination of HCI from alkyl […]

It has the following equation: 2H202 (l) 2H20 (l) + 02 (8) This reaction does occur spontaneously at room temperature with the presence of ltraviolet light; however only very slowly. It occurs far faster when a catalyst is used. Catalysts are substances that speed the rate of a reaction without getting involved in the reaction […]

To Investigate the effect of hydrogen peroxide concentration on enzyme catalase Indroductlon: Enzymes are proteins. They function as biological catalysts. They lower the energy barrier of a reaction so that the reaction can take place at body temperature. Also, they can speed up Metabolic reactions without being changed or used up. During a reaction, an […]

There are many different ingredients in a kitchen that causes a chemical reaction Mth baking soda. This experiment was designed to test 4 kitchen ingredients(Omega oil, water, lemon Juice, and vinegar) mixed with baking soda, to see which one will cause a balloon to expand. It was hypothesized that baking soda mixed with lemon Vice […]

The product of alkenes in this test is an akyl hydrogensulphate. Alkenes are capable of various reactions because of its unsaturation. II. Introduction In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon, Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls. Aromatic hydrocarbons (arenes), […]

Global environmental concern persists over acid rain, despite increased awareness of the planet’s unhealthy condition. Acid rain is defined as rainfall with pH values below 5.6. To fully understand acid rain, it is crucial to comprehend sulfuric acid production. This project aims to explore the process of producing sulfuric acid, its uses, and the environmental […]

Photography is a very complex form of art, which uses standard chemicals and scientific equations. It is a chemical reaction, which occurs when light hits a film or paper emulsion. An emulsion is part of the film or paper, which is very sensitive to light. This is also the part where the chemical reaction takes […]

Procedure: Obtain 8.5 mL of isoamyl alcohol and 15. 0 mL of acetic acid in a 100-mL round-bottomed flask. Add dropwise 5 mL of concentrated sulfuric acid with boiling chips and reflux for one hour. At the end of the reflux cool the round-bottomed flask in a cold water bath. Pour the contents of the […]

Introduction Chemiluminescence is a method used to measure analyte concentration by detecting the optical emission from excited chemical species. This technique differs from atomic emission spectroscopy (AES) as it involves the emission of energized molecules rather than excited atoms. The emitted light bands in chemiluminescence are wider and more intricate compared to those observed in […]

AIMS /OBJECTIVES To understand the reactions of manganese To prepare Mn(acac)3 and calculate percentage yield To calculate the percentage of Mn and acetyl acetone and the empirical formula THEORY Manganese is a first row transition metal that has a tremendous variety of oxidation states that appear in its compounds. The oxidation numbers range from Mn […]

This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction, in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a […]

This study aims to analyze the impact of a specific factor on enzyme activity and explore the function and mechanism of enzymes. Enzymes are proteins that act as biological catalysts, increasing the rate of chemical reactions without being altered themselves. They interact with specific substrate molecules due to their unique shapes, which are determined by […]
