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.

an a study of the gas phase decomposition of phosphine at 120 °C PH3(g)1/4 P4(g) + 3/2 H2(g) the concentration of PH3 was followed as a function of time. 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.

PERTINENT CALCULATIONS Remember: rate = k[C25H30CIN3]"[OH_]" where n =0 since excess OH was used. n3= 1. Refer to your graphs and complete table below Linear correlation (r- value) Graph Kinetic Run I Kinetic Run II Average r- value absorbance vs time 0.9972 0.9955 0.9964 In (absorbance) vs time 0.9978 0.9994 0.9986 2/(absorbance) vs time 0.9805 0.9879 0.9952 2. Based on the average linear correlation (r2 -value) the reaction order, m, with respect to crystal violet, CV, is Explain. 3. Write the rate law. 4. The slope, and therefore pseudo" rate constant, kr', is at T1. CC, and ko' is at T2

Pls help ASAP. Pls show all work. If its false then pls make sure to write the correct statement and why it is false.
