A possible reaction of ethane with chlorine is:

CH3CH3 + Cl2 ---> CH3CH2Cl + HCl

This reaction could conceivably occur by the following chain mechanism involving steps [1], [2], [3] and [4]. The chain initiating step(s) is (are):

[1] Cl2 --> 2Cl*
[2] Cl* + CH3CH3 --> HCl + CH3C*H2
[3] CH3C*H2 + Cl2 ---> CH3CH2Cl + Cl*
[4] Cl* + Cl* ---> Cl2

The name of the ion, s2-, is: sulfurous ion sulfide ion sulfur ion sulfate ion

Identify the missing numbers below to show the result of multiplying the numbers (1.6 × 10-19)(5.0 × 106) = c × 10d

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
