Reduced. The initial color was purple, indicating the presence of the +7 manganese in the MnO4- ion . It was reduced to green, indicative of the +6 manganese in MnO42-. Eventually, a further reduction can occur, indicated by the presence +4 manganese in brown MnO2 (3) Explain, in terms of the transmission and absorption of light by solutions, the variety of colors associated with the different oxidation states of manganese. Natural sunlight is composed of a spectrum of colors which combine to form white light. The color of a liquid is determined by the light transmitted by that liquid. For example, a green liquid transmits green while absorbing all other colors. (4) Determine the oxidation numbers of the atoms in the following: NH3, NO3-, K2Cr2O7, MnO4(, H2O2 In NH3 the oxidation numbers are: N, -3; H +1. In NO3- the oxidation numbers are : N, +5, O, -2. In K2Cr2O7 the oxidation numbers are: K, +1; Cr, +6; O, -2. In MnO4- the oxidation numbers are: Mn, +7; O, -2. In H2O2 the oxidation numbers are: H,+1; O, -1. (5) Use the discs from part 3, and some that you construct yourself, to form some combinations of elements of your choice (making certain the charges sum to zero). Consult chemical reference books to see if the combinations you made are real compounds. Student answers will differ. Make certain the charges on their creations sum to zero and that they check appropriate references such as the Merck Index, CRC Handbook of Chemistry and Physics, or the Internet-based NIST Chemistry Web Book (6) The bonding electron pair is closer to chlorine in HCl than to bromine in HBr, yet the oxidation number of hydrogen in both compounds is +1, while the oxidation number of the halogens is -1. Explain. Oxidation numbers indicate that a bond is polar, but do not indicate the magnitude of the polarity. 67vБ$}█▄▐# $ & ) З И Й / $ j k o p q t u w x y z  А Б Д Е Ж Й О П ┐ └ ┴ Є є ї Ў ў ° ∙ 2 3 4 e f g j Т У Х "-/TlДS╖║¤√ЇЇьфЇьф█Їь╥╨╬╬╠╬╬╬╬╟╬╬ЇьЇьфЇьЇьЇь╜ЇьфЇьЇьЇ╕Ї░Ї░Ї░╨6Б<БB*ph  B*ph <БB*CJH*ph  j-ЁH*H*H*<Б<БB*CJph <БB*CJph <БB*H*ph <БB*H*ph  <БB*ph 6Б5БD67┐└щъ12^_┴┬├$%|}Й К Л . / $ ¤√√√эчэчэчэ√√√√с√√√с√√√√█Д╨^Д╨Д╨^Д╨Дh^Дh & F ╞h╨Д╨^Д╨║■$ % И Й ║ ю , a У Ф Ф Х ДЕRS╖╕╣║¤¤¤єєєєє¤¤¤ээ¤¤ч¤¤¤Д╨^Д╨Д╨^Д╨ ДаД0¤^Да`Д0¤░╨/ ░р=!░"░#Ра$Ра%░еD@ё D NormalCJOJPJQJmH sH tH DA@Є бD Default Paragraph FontZi@є │Z  Table Normal :V Ў4╓ l4╓aЎ _H(k@Ї ┴(No List 2B@Є2 Body TextB*0>@0 Title$a$5Б║        аzЩ║ 67┐└щъ12^_┴┬├$%|}ЙКЛ./$%ИЙ║ю,aУФФХДЕR S ╖ ╕ ╣ ╝ Ш0ААА╩АШ0ААА╩Ш0ААА╩Ш0ААА╩Ш 0ААА╩Ш0ААА╩Ш 0ААА╩Ш0ААА╩Ш 0ААА╩Ш0ААА╩Ш 0ААА╩Ш0ААА╩Ш0ААА╩Ш0ААА╩Ш0ААА╩Ш0ААА╩@ ┐АШ0ААА╩Ш0ААА╩Ш0ААА╩@ ┐АШ0ААА╩Ш0ААА╩Ш0ААА╩Ш0ААА╩@ ┐АШ0ААА╩Ш0ААА╩Ш0ААА╩@ ┐Б@ ┐Б@ ┐Б@ ┐АШ0ААА╩Ш0ААА╩Ш0ААА╩Ш0ААА╩@ ┐АШ0ААА╩Ш0ААА╩Ш0ААА╩@ ┐АШ0ААА╩Ш0ААА╩║$ ║ ║ ╝┐╙╓╝ ├Л.%ИФЦЬ;╝ ::   ДhДШ■╞h^Дh`ДШ■OJQJo(╖Ё        ╝  @АQ Q └°щ ДДQ Q [└ иш║ @ @  Unknown            GРTimes New Roman5РАSymbol3Р Arial3РTimes"qИЁ╨hЎ:ЧЖЎ:ЧЖh$Ёе└┤┤А>4d┘ ЙЁ▀▀Ё                        5GENERATING TESTS AND ANSWER SHEETS FROM SAME DOCUMENT Norman Herr Norman Herr ■  рЕЯЄ∙OhлС+'│┘0МИР╨▄Ё№  , H T `lt|Д'6GENERATING TESTS AND ANSWER SHEETS FROM SAME DOCUMENTч└ Norman Herrч└Normal Norman Herr2└Microsoft Word 11.1@@╘a<%Г┼@╘a<%Г┼h■  ╒═╒Ь.УЧ+,∙о0  hpАИРШ аи░╕ └ 'CSUN┘  6GENERATING TESTS AND ANSWER SHEETS FROM SAME DOCUMENT Title ■   ■   ■    !"#$■   ¤   '■   ■   ■                                                                                                                                                                                                                                                                                                                                                           Root Entry         └FОпъВ┼)А1Table             WordDocument        SummaryInformation(    DocumentSummaryInformation8            CompObj    XObjectPool            ОпъВ┼ОпъВ┼            ■                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           ■      └FMicrosoft Word Document■   NB6WWord.Document.8
