Answer:
Demand for recycled paper has increased as consumers have become more aware of the environmental issues surrounding waste disposal. Paper is a natural raw material made from renewable wood and plants. Recycled paper is made from waste paper and paperboard. Both new paper and recycled paper contain traces of heavy metals. However, some types of recycled paper contain more heavy metals than new paper due, in part, to the inks used for printing or adding color to the original paper. Metals can migrate from the paper packaging and containers used for food to the food itself. This metal migration is controlled and monitored to reduce the exposure of humans to heavy metals. Food agencies in each country determine the limit of cadmium, zinc, nickel, and copper in packaging materials. Most countries impose a limit of heavy metals in recycled paper not to exceed 100.0 ppm or 100.0 . The limit for lead in eggfruit, or vegetable-packaging is lower-not to exceed-20.0 mg/kg. The table in Figure a lists the results of the analysis of samples of recycled paper produced by a manufacturer during a three-month period. The goal of the manufacturer is to reduce the amount of heavy metals-especially lead-in the recycled paper it produces and sells. From March to May, the manufacturer varied the
methods of production each month to determine which method would produce paper with the lowest metal content. Each month, lab technicians cut small samples of recycled paper with an area of 1.000 and a thickness of 0.0500 The technicians then prepared the samples for analysis. The average density of the samples is Use the information provided in the figure to answer the
following questions:
a. Did the company reduce the amount of lead in its product between March and May?
b. Which metal was not reduced?
c. Each month's sample represents a different manufacturing process. Which process would you recommend the manufacturer choose to continue to use over the next year while additional processes are tested? Why?
d. What is the total amount of the five metals for the April sample (in mg/kg)?
e. What is the total mass (in mg) of the five metals for the April sample found in the 1.000 sample?
f. Lead has four stable isotopes: 204
Explanation:
so this problem gives us a lot of information and asked us to answer several questions. So, Letter A says, did the company make reduce the amount of lead in its product between March and May? And the answer is yes. The PB levels went from 3.5 to 2.8 22.4, so it was reduced. Be asks which medal was not reduced. And that would be sync because England from 2.723 point 2.723 2 to 3.7 so zinc increased. It was not reduced. See says each month sample represents a different manufacturing process.
The themes of the book include morality and womanhood. Cassy commits infanticide not because she wanted to do it but because she had no choice. She was a slave and that meant she did not have the capacity to raise the baby. Despite this, she still made her decision to kill the baby and that shows her 'moral weakness.'
Answer:
The correct answer is "Don Quixote is an idealist and Sancho Panza is a realist".
Explanation:
In the famous novel "The Ingenious Gentleman Don Quixote of La Mancha" by Miguel de Cervantes, Don Quixote is portrayed as a man that avoids reality and prefers to see it as part of a knights novel, where he is the protagonist of glorious deeds. Don Quixote is a clear example of an idealist. On the other hand, Don Quixote's squire Sancho Panza, is a sarcastic man that function as a realist and helps his master to see the world as it is. For instance, Sancho Panza warned Don Quixote when he tried to fight "ferocious giants" that were in fact windmills.

Explanation:
Bilbo does confront Smaug the dragon and, like his encounter with Gollum, he matches wits with him in conversation. During the conversation, however, he looks for the vulnerable spot on Smaug's body. Bilbo knows Smaug must be killed and, rather than avoiding it, Bilbo develops a strategy for accomplishing it.
