Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from

Investigation and Preparation of Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other. Esters

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Starting with the largest distance‚ place either one or two ends onto your partners skin (ALTERNATE RANDOMLY so the partner can’t guess!!!) 7. Have lab partner tell you how many ends they can feel. Do this 5 or 6 times. 8. Then try the next smaller distance and repeat steps 6 and 7. 9. Record

Beet Lab By: Sumeet Grewal Purpose: The purpose of this lab was determining the effect of surface area on the beets ability to interact with the environment. Three similar sizes of beets were assigned. Each beat was cut up into different sizes as one large piece‚ two smaller pieces and eight tiny pieces. All three different slices of beets were placed in their own containers and tested. Observation: While the lab was going on‚ it was noticed the tiny pieces of beet were doing the best while the

The Sustainability Lab introduced what defines sustainability and how important it is in any environment through the simulation of a fictional island environment. It showcased what steps and requirements are needed to maintain an environment without it plunging into deterioration‚ plagued with barely a few to none resources to unlimited desires. Subsequently‚ both the data table and the graph display a direct correlation between the number of people in the island environment and the number of water

Lab Report 3: Daphnia‚ Human and Crayfish Cardiac Activity Introduction An electrocardiogram‚ abbreviated as ECG in this report‚ is a visual representation of an organism’s atrial and ventricular depolarization and repolarization. Previous research has shown that although there is variability in the amplitude and shape of the waves of ECG‚ dependent on the subject’s health‚ it follows a universal pattern that can be used effectively for biometrics. The experiments discussed in this lab report were
