Lab 7: Catalysts Introduction Pre-Lab Questions 1. What is a catalyst? An enzyme is a biological catalyst that speeds up chemical reactions in the body. 2. If you continue to add more catalyst will the speed of a reaction always continue to increase? Explain your answer. It will continue to speed up the reaction until there is more catalyst than the limiting reactant. 3. In this lab you will produce oxygen and water from hydrogen peroxide (H2O2). Write a balanced reaction equation for this reaction

Simple and Fractional Distillation Experiment II Stancy Saji‚ 18 September 2014 Purpose Experiment II involved two kinds of distillation techniques: simple and fractional. Simple distillation was done to separate ethyl acetate—which has a usual boiling point of 77º—from a less volatile component‚ while fractional distillation was done to distinguish an ethyl acetate/n-butyl acetate mixture‚ which has boiling points of 77º and 125 º‚ respectively. Results and Discussion As previously stated the

oxygen increases so does the number of fish observed. However‚ when the dissolved oxygen reaches 14 ppm the number of fish decreases to 10. So‚ 6ppm and 14ppm‚ 8ppm and 16ppm‚ and finally 10ppm and 18ppm‚ have a similar number of fish observed. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. If the amount of dissolved oxygen is increased‚ then the number of fish observed will increase. 3

Fortran Exercise #2: Coefficient Of Restitution 1. DEFINITION In this lab‚ we shall be studying the coefficient of restitution of a superball. The coefficient of restitution‚ COR‚ is the ratio of the bounce-back velocity to the original velocity of an object undergoing impact (such as a ball impacting the ground after being dropped from an initial height). Using the principle of the conservation of energy‚ the COR can be used to relate the bounce-back height to the original height of a ball dropped

Diversity and Ubiquity of Microbes Pre-Laboratory Questions 1. What environmental settings would you expect to provide rich sources of microbes‚ in terms of overall numbers and different microbial types? Since the most of the microbes are ubiquitous‚ they are readily found in public bathrooms‚ phones‚ countertops‚ door handles‚ kitchen sinks‚ and human body parts such as the face and hands (Sherwood‚ 2017). In addition‚ public places exemplified by hospitals‚ grocery stores‚ and schools present an
