Chapter 2: Q2.2-2ITD (page 33)

Recall that 14C has a half life of 5,730 years. To calibrate the x-axis for 14C decay, write the time before present in years below each half-life.

Short Answer

Expert verified

14C has a half-life of 5,730 years.

Time in years at one half-life would be 5,730.

Step by step solution

01

Step 1:Time in years at one half-life

14C has a half-life of 5,730 years.

Time in years at one half-life would be 5,730.

02

Time in years at two half-lives

Years in number of half-lives = Half-life X Number of half-lives

Years at two half-lives=5,730脳2= 11,460

03

Time in years at three half-lives

Years at three half-lives =5,730脳3= 17,190

04

Time in years at four half-lives

Years at four half-lives=5,730脳4=22,920

05

Time in years at five half-lives

Years at five half-lives=5,730脳5=28,650

06

Time in years at six half-lives

Years at six half-lives=5,730脳6=34,380

07

Time in years at seven half-lives

Years at seven half-loves=5,730脳7=40,110

08

Time in years at eight half-lives

Years at eight half-lives=5,730脳8=45,840

09

Time in years at nine half-lives

Years at nine half-lives=5,730脳9=51,570

10

Time in years at ten half-lives

Years at ten half-lives=5,730脳10=57,300

The reactivity of an atom arises from

(A) the average distance of the outermost electron shell from the nucleus.

(B) the existence of unpaired electrons in the valence shell.

(C) the sum of the potential energies of all the electron shells.

(D) the potential energy of the valence shell.

We can represent atoms by listing the number of protons, neutrons, and electrons-;for example, 2p+, 2n0, 2e-for helium. Which of the following represents the 18O isotope of oxygen?

(A) 7p+,2n0, 9e-

(B) 8p+,10n0, 8e-

The percentage of naturally occurring elements making up the human body (see table2.1) is similar to the percentage of these elements found in other organisms. How could you account for this similarity among organisms?

Female luna moths (Actias luna) attract males by emitting chemical signals that spread through the air. Male hundreds of meters away can detect these molecules and fly towards their source. The sensory organs visible in the photograph are shown here. Each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. Based on what you learned in this chapter, propose a hypothesis to account for the ability of a male moth to detect a specific molecule in the presence of many other molecules in the air. What predictions does your hypothesis make? Design an experiment to test one of these predictions.

Which coefficients must be placed in the following blanks so that all atoms are accounted for in the products?

\({C_6}{H_{12}}{O_6} \to \_\_\_{C_2}{H_6}{O_{}} + \_\_\_C{O_2}\)

(A)2,1

(B) 3,1

(C) 1,3

(D) 2,2
