ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but

Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The chemical reaction is shown as 2H2O2 = 2H2O + O2 (Keilin and Hartree 397). The reaction involves primarily the adsorption of hydrogen peroxide at the catalase surface. The decomposition of hydrogen peroxide by catalase is regarded as involving

“to destroy disease-causing microbes”(cdc.gov). That means that antimicrobials fight and destroy organism such as bacteria. We use antimicrobials to clean are house and protect ourselves from bacterias. One example of an antimicrobial that we use in our home is bleach. Bleach contains the ingredient hypochlorous acid. This ingredient “causes bacterial proteins to unfold and stick to one another‚ making them nonfunctional

Mr. Mihordea Motion of Atoms and Molecules lab summary In this lab the standard heat of combustion of magnesium was calculated by using the calorimeter. Also‚ the point of combustion of magnesium was to see how much heat would be released from fireworks such as sparklers. The concept of this lab was to find the difference in temperature from the beginning to end of combustion of magnesium and calculate the standard heat of combustion of magnesium

paraminophenol by using iron powder. Para-aminophenol crystallises out from the mother liquid which is subsequently centrifuged. Para-aminophenyl crystal is then reacted with acetic anhydride to produce pure paracetamol. The reactions are summarised as shown below: Lab scale manufacture Paracetamol can be easily prepared in the laboratory using phenol. Phenol reacts with sodium nitrate and separate para nitro phenol from outho nitro phenol. Then para nitro phenol is converted into para amino
