Chemical reaction

Enzymes are known as catalysts that cause reactions to occur more rapidly by lowering the reaction’s activation energy. A reaction’s activation energy is known as the minimum amount of energy required to get a chemical reaction started1. In order for cells to efficiently manage thousands of different chemical reactions, they make use of biological catalysts. Without these catalysts, biological reactions would not be able to proceed at a proper rate necessary to maintain life. Most, but not all,…

It is known that the reaction was a single replacement reaction, so the products are magnesium chloride and hydrogen. Therefore, the balanced equation would is: Mg + 2HCl → MgCl2 + H2. This equation is used to discover the amount moles of hydrogen gas produced by looking at the mole ratios. The…

hypochlorite are able to produce second degree burns on a person within 10 seconds. In order for a second degree burn to be possible we must reach a temperature of at least 56°C (133°F) in order to create burns up to third degree for the time the chemical stayed on the worker. Now the dumpster contained 6% mass sodium hypochlorite and 20.0% mass of sodium thiosulfate. Which when we calculate the molarity of each substance we get .81M in each substance. In our experiment we decided to use .5 M…

are aware of how we define challenges. A ‘challenge’ can be on an emotionally reactive level, anything from a small negative reaction to a full on meltdown and all the emotions that can include. Or a ‘challenge’ can be what appears to come from external events such as loosing a job, illness and other life events. A ‘challenge’ is anything at all that creates a reaction within you that is not a balanced one! I want to keep this information as simple as possible, because it does not need to be…

Chemistry Lab Report NAME: Serina Alashi DATE: TITLE: Decomposition reaction: hydrogen peroxide (H2O2) decomposed into hydrogen and oxygen ( H2 and O2) RESEARCH QUESTION: How will changing the concentration of hydrogen peroxide affect the rate of reaction, that is represented by the increase in pressure over time? Introduction: Hydrogen peroxide is a chemical compound of hydrogen and oxygen. It is a very strong oxidant but weak in water solution. Hydrogen peroxide decomposes into water…

combustion reaction tends to be less complete. The bigger the molecule of alkenes, the more likely to get a yellow, sooty flame. B. Action of sulphuric acid (to be performed under fume hood) 1. When concentrated sulphuric acid was added into cyclohexane, is there any sign of reaction? Ans: No. 2. Do the substances mix or are there two separate layers in the test tube when concentrated sulphuric acid was added into cyclohexene. Explain the reason behind the reaction. Ans:…

speed up chemical reactions by lowering the activation energy required. This means that a catalyst helps reactions occur at a greater speed and lower temperature. For this lab report we focused on the enzyme Tyrosinase, Tyrosinase is an enzyme that produces melanin from the amino acid tyrosine. Three different reactions were catalyzed by Tyrosinase; for the first reaction tyrosine is oxidized into DOPA by tyrosinase. Second, tyrosinase oxidizes DOPA to DOPAaquinone and the third reaction…

sulphate decahydrate thermally decomposes to anhydrous sodium sulphate at 50⁰ C and cools to form anhydrous sodium sulphate. Using Hess's Law the enthalpy and entropy changes of this process can be determined in order to deduce the spontaneity of the reaction. The transition temperature was determined by melting the hydrated crystals at 50⁰ C and allowing them to cool until a constant temperature was reached. The molar enthalpy and molar entropy changes were determined using calorimetric…

Some flame and a huge amount of smoke will be liberated from the rapidly burning sugar. The chemical formula of the reaction is described as below: 48KNO3 + 5C12H22O11 → 24K2CO3 + 24N2 + 36CO2 + 55H2O There are two ways the smoke bombs can be made at home. The first way is as mentioned above in the experiment. The second way involves using celluloid material…

Interpretation 1. Theoretical Lab Discussion This lab occurs due to enzyme kinetics, and the kinetics molecular theory. Enzyme kinetics is the study of chemical reactions that are catalysed by enzymes, and during the experiments, the reaction rate was measured by the effects of the varying conditions the substrate was in. Influence of Catalase Concentration The higher the concentration of the enzyme catalase, the function of the enzyme occurs better. As the number of disks increased, the…
