Based on a grade 11 chemistry student, answer the following question based on the provided tables: Part G:  Final Identification of the Poison By this time, Tylenol has been pulled off the shelves at all of the stores in the area and a nationwide recall has been announced.  Several suspicious capsules have been found and tested.   The contents of the capsules contain a compound with a nitrogen content of greater than 15% and a carbon content of less than 50%.   What is the poison in the capsule?  Provide calculations to support your answer.

2 Please introduce your thoughts and discuss Chemistry and Food. How does Chemistry affect the Food supply, production, storage, transportation, availability, quality, quantity, etc. Are there any issues with Chemistry involved in all stages of food production? Do you think Chemistry is doing more harm than good or it is the other way around? If so, what are the alternatives? Do you think educating general public in the field of Chemistry helps people understand more about Chemistry's impact on food? Provide at least two references in your original 300 words post.

Would someone please help me answering questions #1, #3 and #5? Thank you

C-D I4 EI Imagine you are a farm owner who lives close to a small town. Just over 30% of the town's population is over the age of 65, thus you are concerned about the potential effects of pesticide drift from your farm. What is 1 strategy that you (the concerned farmer) could use to prevent pesticide drift from occurring? * lili 日

1. What are the parts of the chemical hood and biosafety cabinet including the functions. Include also the strategic places in the lab where both should be located and why?

Like anatomy and physiology, chemistry may be a somewhat scary subject for you. Think of it this way: Chemistry is simply the study of matter, its composition, structure, properties, and the changes matter may undergo. Your goal in training as a cosmetologist is not to become a scientist, but to develop a comfort level with the basics and an ability to discuss chemistry in relation to your profession. This will increase your credibility significantly with your clients, especially during the consultation process. In the space provided, write how chemistry affects your everyday life.

- Why is high pressure an attractive approach to sterilization and food preservation? a. It is much cheaper than thermal approaches. b. It preserves nutritional and sensory properties of foods much better than heat. c. It allows many other kinds of containers that cannot otherwise be used with heat. d. High-pressure equipment offers higher profit margins for manufacturers. So biophysical chemists can have jobs e.
