Answer the following question given this paragraph:   Appendix: Periodic Table of the Elements In this chapter, we present some data on the chemical elements. The periodic table, introduced in Chapter 3 "Atoms, Molecules, and Ions", lists all the known chemical elements, arranged by atomic number (that is, the number of protons in the nucleus). The periodic table is arguably the best tool in all of science; no other branch of science can summarize its fundamental constituents in such a concise and useful way. Many of the physical and chemical properties of the elements are either known or understood based on their positions on the periodic table. Periodic tables are available with a variety of chemical and physical properties listed in each element’s box. What follows here is a more complex version of the periodic table than what was presented inChapter 3 "Atoms, Molecules, and Ions". The Internet is a great place to find periodic tables that contain additional information. One item on most periodic tables is the atomic mass of each element. For many applications, only one or two decimal places are necessary for the atomic mass. However, some applications (especially nuclear chemistry; see Chapter 15 "Nuclear Chemistry") require more decimal places. The atomic masses in Table 17.1 "The Basics of the Elements of the Periodic Table" represent the number of decimal places recognized by the International Union of Pure and Applied Chemistry, the worldwide body that develops standards for chemistry. The atomic masses of some elements are known very precisely, to a large number of decimal places. The atomic masses of other elements, especially radioactive elements, are not known as precisely. Some elements, such as lithium, can have varying atomic masses depending on how their isotopes are isolated. The web offers many interactive periodic table resources. For example, seehttp://www. ptable.   Q: What organizational tool, arguably the best in all of science, lists all the known chemical elements, arranged by atomic number?   Choices:  - tide table  - logic table  - spreadsheet  - periodic table  A:
periodic table


(Question)
Answer the following question given this paragraph:   Alkenes can react with halogens to form dihalides.   Q: Alkenes react with what to form dihalides?   Choices:  - antioxidants  - amines  - oxides  - halogens  A:
(Answer)
halogens


Ques: Answer the following question given this paragraph:   Transpiration is like evaporation because it changes liquid water to water vapor. In transpiration, plants release water vapor through their leaves. This water vapor rises into the atmosphere.   Q: What is it called when plants release water vapor through their leaves?   Choices:  - propagation  - evaporation  - respiration  - transpiration  A:
Ans: transpiration


(Q).
Answer the following question given this paragraph:      Q: Diet correlates with the length of what organ system in vertebrates?   Choices:  - respiratory  - reproductive  - circulatory  - digestive  A:
(A).
digestive


Ques:Answer the following question given this paragraph:   Cleaning groundwater in an aquifer requires bioremediation or chemical remediation. Bioremediation uses microorganisms to consume a pollutant. Chemical remediation destroys the contaminant.   Q: What do you call a process that uses microorganisms to consume a pollutant?   Choices:  - siltation  - filtration  - biodegradation  - bioremediation  A:

Ans:bioremediation


Question: Answer the following question given this paragraph:   The use of electric current to encode information is called electronics. Electronic signals may be digital or analog signals. Both types of signals encode information by changing the voltage of an electric current, but they do so in different ways.   Q: What do we call use of electric current to encode information?   Choices:  - products  - metals  - ferious  - electronics  A:
Answer:
electronics
