What’s in a name?
Henry Louis Gates Jr. (1989)
The question of color takes up much space in these pages, but the question of color, especially in this country, operates to hide the graver questions of the self.

- Trey Ellis, 1989
I had forgotten the incident completely, until I read Trey Elli’s essay, “Remember My Name,” in a recent issue of the Village Voice (June 13, 1989). But there, in the middle of an extended italicized list of the bynames of “the race” (“the race” or “our people” being the terms my parents used in polite or reverential discourse, “jigaboo” or “nigger” more commonly used in anger, jest, or pure disgust), it was: “George”. Now the events of that very brief exchange return to my mind so vividly that I wonder why I had forgotten it.
My father and I were walking home at dusk from his second job. He “moonlighted” as a janitor in the evenings for the telephone company. Every day, but Saturday, he would come home at 3:30 from his regular job at the paper Mill, wash up, eat supper, then at 4:30 head downtown to his second job. He used to make jokes frequently about a union official who moonlighted. I never got the joke, but he and his friends thought it was hilarious. All I knew was that my family always ate well, that my brother and I had new clothes to wear, and that all of the white people in Piedmont, West Virginia, treated my parents with an odd mixture of resentment and respect that even we understood at the time had something directly to do with a small but certain measure of financial security.
He had left a little early that evening because I was with him and I had to be in bed early. I could not have been more than five or six, and we had stopped off at the Cut-Rate Drug Store (where no black person in town but my father could sit down to eat, and eat off real plates with real silverware) so that I could buy some caramel ice cream, two scoops in a wafer cone, please, which I was busy licking when Mr. Wilson walked by.
Mr. Wilson was a very quiet man, whose stony, brooding, silent manner seemed designed to scare off any overtures of friendship, even from white people. He was Irish as was one-third of our village (another third being Italian), the more affluent among whom sent their children to “Catholic School” across the bridge in Maryland. He had white straight hair, like my Uncle Joe, whom he uncannily resembled, and he carried a black worn metal lunch pail, the kind that Riley carried on the television show. My father always spoke to him, and for reasons that we never did understand, he always spoke to my father.
“Hello, Mr. Wilson,” I heard my father say.
“Hello, George.” I stopped licking my ice cream cone, and asked my Dad in a loud voice why Mr. Wilson had called him “George.”
“Doesn’t he know your name, Daddy? Why don’t you tell him your name? Your name isn’t George.”
For a moment I tried to think of who Mr. Wilson was mixing Pop up with. But we didn’t have any Georges among the colored people in Piedmont; nor were there colored Georges living in the neighboring towns and working at the Mill.
“Tell him your name, Daddy.”
“He knows my name, boy,” my father said after a long pause. “He calls all colored people George.” A long silence ensued. It was “one of those things”, as my Mom would put it. Even then, that early, I knew when I was in the presence of “one of those things”, one of those things that provided a glimpse, through a rent curtain, at another world that we could not affect but that affected us. There would be a painful moment of silence, and you would wait for it to give way to a discussion of a black superstar such as Sugar Ray or Jackie Robinson.
“Nobody hits better in a clutch than Jackie Robinson.”
“That’s right. Nobody.”
I never again looked Mr. Wilson in the eye.

1a Etapa: o composto A (C7H6O) sofre oxidação em solução básica de permanganato de potássio. O produto gerado, após neutralizado, é o ácido benzoico;
2a Etapa: o ácido benzoico reage com etanol em solução ácida, produzindo o composto B e água;
3a Etapa: o composto B sofre forte redução com hidreto de lítio-alumínio em éter, gerando dois produtos que, depois de neutralizados, formam então o composto C e o etanol.
Considerando as etapas supracitadas, são feitas as seguintes afirmações:
I) o composto A e o composto C são isômeros.
II) o composto B é um éster.
III) o composto B é o acetato de benzila.
Com base na análise das afirmações acima, assinale a opção correta.
I. Acetona;
II. Neopentano;
III. Fluoreto de lítio;
IV. Etanamida;
V. Pentano.
Assinale a alternativa que apresenta a sequência correta, conforme a ordem crescente de ponto de ebulição.
As equações que representam as semirreações de cada espécie e os respectivos potenciais- padrão de redução (25 ºC e 1 atm) são apresentadas a seguir.
Zn2+(aq) + 2 e- → Zn (s) Eo = - 0,76 V
Ag+ (aq) + 1 e- → Ag (s) Eo = + 0,80 V
Com base nas informações apresentadas são feitas as afirmativas abaixo.
I – No eletrodo de zinco ocorre o processo químico de oxidação.
II – O cátodo da pilha será o eletrodo de prata.
III – Ocorre o desgaste da placa de zinco devido ao processo químico de redução do zinco.
IV – O sentido espontâneo do processo será Zn+2 + 2 Ago → Zno + 2 Ag+
V – Entre os eletrodos de zinco e prata existe uma diferença de potencial padrão de 1,56 V.
Estão corretas apenas as afirmativas

Com relação a estas substâncias citadas, são feitas as afirmativas abaixo.

O fosgênio é um gás extremamente venenoso, tendo sido usado em combates durante a
Primeira Guerra Mundial como agente químico de guerra. É assim chamado porque foi primeiro
preparado pela ação da luz do sol em uma mistura dos gases monóxido de carbono (CO) e cloro
(Cl2), conforme a equação balanceada da reação descrita a seguir: CO (g) + Cl2 (g) COCl2 (g).
Dados:
