Read and interpret the following information using the following abstract from a scientific journal article. In 2-3 sentences, summarize what you understand from this research

Dr. X claims that she has found a new remedy (carrot extract) to cure acne. She scores an interview with the science writer for a local newspaper, and gets a brief article written about her and her claims in that newspaper. The article does not contain any experimental evidence, but mentions that Dr. X accidentally splashed some carrot extract on her face and found that the acne was reduced a few days later. Student Y finds the article and cites it as a source for a paper he is writing for class, as evidence that acne has been cured. (a) Is this finding a fact, a theory, a hypothesis, or an observation? Explain why you think so. (b) Was it OK for Student Y to use the newspaper article as evidence for his paper? Explain why or why not.

It was found that a graph of In[PH3] versus time in seconds gave a straight line with a slope of -2.81×10-2 s1 and a y-intercept of -4.31. Based on this plot, the reaction is | order in PH3 and the rate constant for the reaction is s1.

Experiment 4: Preparation and Properties of Hydrogen and Oxygen Gases Toriana Mieer -Jones Name: Section: Lab Instructor: L/26 Date: Pre-Lab Exercise 4 1. In this experiment, simple chemical reactions are used to generate small quantities of hydrogen and oxygen gases. These methods would be too expensive and too complicated if large quantities of these gases were needed, however. Use your textbook, a chemical encyclopedia, or an online source to look up the major industrial methods of preparing very large quantities of these gases. Summarize your findings here. ono od te led bateono to n
