7. You can see an MSDS below. Please answer the following questions related to the MSDS. a) What is the name of this chemical? b) What should you do if someone drinks the chemical? c) Would this chemical catch on fire if it was exposed to flames? d) If this chemical gets in your eye what should you do? e) What color is this chemical? f) What should you do if someone spills a small amount of the chemical?

Why are ducks waterproof? It’s because they produce copious amounts of oils from their uropygial glands and spread it across their feathers. In this exercise, we’ll be investigating the molecular structure of one of these preen oils to determine how it keeps ducks dry. Q.5 - Preen oil is actually a complicated mixture of many different organic compounds, such as the structure seen previously.. Ornithologists have determined that birds often use preen oil compounds for scent recognition. Below, several different chemicals isolated from preen oil are shown, along with their vapor pressures at room temperature. p-cymene has the highest vapor pressure, meaning it is the most easily evaporated compound of the three listed. Explain why p-cymene has a higher vapor pressure at room temperature compared to the other compounds. Make sure to explain what holds the p-cymene in the sample. (Image attached)

Arrange these substance according to how many drops we could add to a penny before the "bubble" popped, FEW DROPS (left-most) to MANY DROPS (right-most). The description labels on the images are small, so use the following legend to identify the materials: A: vegetable oil B: motor oil C: dish soap D: syrup E: honey A CITE EVIDENCE from your Learning Experience and provide REASONING for why you arranged these substances in this order.

Determine the structures of the missing organic molecules in the following reaction: Y II OH X + H₂O H+ H* OH Note: Molecules that share the same letter have the exact same structure. In the drawing area below, draw the skeletal ("line") structures of the missing organic molecules X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Click and drag to start drawing a structure. C X :0 Ś m c+

Based on a grade 11 chemistry student, answer the following question based on the provided table:Part B:  Other Cases EmergeRead Case File 3.  Based on these new cases, it now seems clear that people are being poisoned by something in the Tylenol. Fast-Acting PoisonsWhatever the poison is, it is very fast acting as victims collapsed within minutes of taking the pills. After some research, and based on your love of Agatha Christie novels, you find five common poisons that work quickly and can cause death within a few hours – aconite, coniine, cyanide, nicotine, strychnine. Use the information contained in table 6 to determine the empirical formula, molecular formula, and fatal volume for the two poisons not completed in the table.
