the market everyone experiences the same thought: “Organic or regular?” If one does decide to go organic‚ a few things come to mind: Is organic worth the price? How do I know if it really is organic? Why should I buy the organic five-dollar raspberries‚ while the normal raspberries are only two dollars? These are thoughts that strike every one’s minds while shopping at their local super market. The majority of people would turn away from organic products due to the price. Not only is the price a

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

Question 1 Critique Dr. Honeydew’s report. Specifically‚ discuss what is missing and how the missing information should have been presented. First the PH measurements‚ Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water‚ etc.). In regards to the absorption spectroscopy‚ the method by which the concentration was obtained is questionable. Was the concentration known before the experiment
