Chapter 1, Problem 12Q

As part of a science project, you study traffic patterns in your city at an intersection in the middle of downtown. You set up a device that counts the cars passing through this intersection for a 24-hour period during a weekday. The graph of hourly traffic looks like this.

Chapter 1, Problem 12Q, As part of a science project, you study traffic patterns in your city at an intersection in the

a. At what time(s) does the highest number of cars pass through the intersection?

b. At what time(s) does the lowest number of cars pass through the intersection?

c. Briefly describe the trend in numbers of cars over the course of the day.

d. Provide a hypothesis explaining the trend in numbers of cars over the course of the day.

e. Provide a possible experiment that could test your hypothesis.

1. Marie Curie was a Polish scientist that specialized in chemistry and physics. She wanted to understand how X-rays worked and noticed in her studies that the element, Uranium, gave off rays that could be measured but did not know what the rays were. She assumed that the rays came from the uranium itself instead of through different molecules interacting with each other. To study the rays, she used an instrument, called an electrometer, that studied the electricity that the rays passed through the air. Through this she was able to discover that the more uranium atoms there were in a compound, the stronger the rays that came off of it. She used this discovery to test other minerals that emitted more rays than Uranium, and discovered the elements Thorium, Polonium and Radium. Through her discoveries of these elements, scientists were able to find the structure of the atom and even how the rays can be used to fight cancer. What was Marie Curie’s observation? 2.

We experimented on various elements: Mossy Zinc, Aluminum Turnings, Copper Turnings, Activated Carbon, and Iron Fillings. We identified the physical properties based on Color, Luster, Form, and Conductivity and the chemical properties based on reaction to HCl and CuCl2. We were tasked to identify if the given elements were metals or nonmetals. The result of our observation is shown in the image. Based on this, what elements are metals and nonmetals?  Iron is known to be a metal however, the iron fillings did not conduct electricity and do not have a metallic luster. Does that mean they are not metal? Is it right to say "corroded" in the CuCl2, when the sample formed rust-like material on its surface?
Magnesium reacts explosively with oxygen to form magnesium oxide. Which is NOT true of this reaction?A. The mass of magnesium oxide produced equals the mass of magnesium consumed plus the mass of oxygen consumed.B. The reaction describes the formation of a new substance.C. The product of the reaction, magnesium oxide, is a chemical compound.D. Magnesium oxide has physical and chemical properties similar to both oxygen and magnesium.
