Purpose The purpose of this experiment is to determine the rate constants‚ k1‚ for the methyl acetate hydrolysis reaction at 25 °C and 35 °C‚ as well as the overall activation energy of the reaction. Methods Methyl acetate was placed in an HCl solution‚ in which it reacts with water to form acetic acid over time. At each time interval‚ an aliquot of the mixture was removed for titration against NaOH to determine the concentration of the acetic acid produced. From the amount of acetic acid produced

molecular level – Tutoring for biology Saturated fat vs. unsaturated fat Saturated fat has a lot of single carbon bonds. This makes them much straighter in shape and therefore easier to stack together. It’s called “saturated” fat because the molecule has the maximum amount of hydrogen atoms attached to it as possible. Unsaturated fat has double carbon bonds. Each double carbon bond means two less hydrogen atoms on the molecule. Unsaturated fat also is kinked at each double bond‚ disrupting the

Truth has been debated since the begging of time and may be debated forever‚ but one thing is certain‚ that there is truth. There is a universal truth and reality of how things are‚ but it is hard for people to agree and come to a consensus of it because of backgrounds and beliefs. What we can do to help find truth is interact with others in such a way that we learn from them and show each other different perspectives of truth‚ one day we all might what find it. I think that this is very unlikely

solely descriptions‚ staying removed from the situation. While this can keep biases from clouding perception‚ being so far removed can also inhibit the ability to perform analysis due to not being fully submerged in the environment. I start the report with assumptions on the behavior of the young boy whom I nicknamed “Tube-Boy” as well as making assumptions about the players in the soccer field nearby. Starting with assumptions can lead to faulty analysis as I am more likely to notice or focus on events

Girls Can We Educate We Dads? Diction. “Girls can we educate we dads” is a poem written by James Berry‚ a Jamaican poet in the 1900’s which speaks about a girl who criticizes her dad’s stereotypical views about girls’ behavior and thoughts.

Introduction The health-care industry has taken a more business type approach when it comes to caring for patients. In order for this method to succeed‚ patient safety and satisfaction must be their number one priority. A way for them to achieve this is to implant a radio-frequency identification device (RFID) on each patient. RFIDs are “smart labels” or “intelligent barcodes” that are used to transfer data from a tag attached to an object or a person (Sewell and Thede‚ 2010‚ p. 370). The purpose

FM 2 FLOW ALONG A VENTURI TUBE Summary The objectives of the experiment is to study the validity of the Bernoulli equation and to determine the coefficient of discharge‚ Cd‚ by calibrating the venturi tube as a flow meter. To investigate the validity of the Bernoulli equation‚ the static pressure is taken at each tapping and the total head is determined for the maximum difference setting. The velocity head is calculated using the Bernoulli equation. To calculate Cd‚ the volumetric flow rate
