- A discharge pipe releases small amounts of various alcohols from an industrial fermentation process into a lake. Local scientists would like to estimate the rate at which the alcohols are degrading in the lake. One of them, butanol (C4H9OH), is released to the lake at a rate of 20 kg/day. Butanol is measured in the lake water on several occasions at a concentration of 10-4 kg/m3; no butanol is detected in the inflowing stream. Average streamflow at the outlet of the lake is measured to be 3 x 104 m3/day. What is the magnitude of internal sinks of butanol? Assume there is not butanol exchange with the atmosphere.Is it acceptable to recycle the containers of hazardous chemicals? Why or why not? Explain your answer within the context of chemical safety.Which state of matter of waste is most difficult to remediate: solid, liquid or gas? Give a brief explanation.
- what types of content that we can discuss on this topic? "non-stick cooking utensils- are they safe for us"The World Health Organization (WHO) recommends us to limit "free sugar" intake to no more than 5 % of the total daily Calories consumed. Sugars like sucrose are considered "free sugars" and provide about 4 Calories per gram. If an individual consumes 2000 Calories in a day, what is the maximum amount of sugar they are advised to take in? How does this amount compare to the added sugars found in popular soft drinks?A styrofoam cup was analyzed in a lab and found to contain 92% by mass carbon. How much carbon can be found in a stack of polystyrene cups with a total mass of 569 grams?
- Discuss about this topic non-stick cooking utensils- are they safe for usBefore slow cooking a meat (for example, in a crockpot/slow-cooker) you will often find instructions to sear the meat on high heat in an oiled skillet for a few minutes before transferring it to the crockpot. The searing is brief – not long enough to cook the meat thoroughly. Despite myth/legend, the searing will not “seal in the juices”. What is the searing for?In four or more sentences, explain the advantages of using biodegradable plastic.
