O experimento conhecido como Teste da Chama
consiste em aquecer, no bico de Bunsen, com o
apoio de uma vareta de vidro, um chumaço de
algodão embebido de soluções de sais de um
metais que podem ser bário, potássio, etc. Após

Química
As duas proposições abaixo estão relacionadas com a preparação e separação de compostos opticamente ativos:
( ) os organismos vegetais e animais produzem seus compostos opticamente ativos já na forma (dextrógira ou levógira) adequada a seu metabolismo. No laboratório, porém, as reações comuns produzem misturas racêmicas.
( ) a separação de uma mistura racêmica não é fácil em virtude de dois enantiomorfos terem propriedades físicas iguais.

O programa Fantástico (04.10.2009) da Rede Globo noticiou com grande estardalhaço: “Matéria para fabricar bomba atômica é vendida no Amapá”. A notícia se referia à Torianita, um mineral composto por óxido de tório, contendo hélio e os óxidos de urânio, lantânio, cério , praseodímio e neodímio. Da leitura das informações acima e também a partir de seus conhecimentos, assinale a única alternativa verdadeira:

Química
Construções de ciclovias nas grandes cidades
representam uma possibilidade saudável de
combate ao trânsito e ao excessivo uso de
veículos (automóveis, motos e ônibus) e poupam
queima de combustível e, conseqüentemente,
diminuem a poluição do ar. As ciclovias
proporcionaram mudança de hábito com o
surgimento de novos ciclistas, alguns
abandonando seus veículos, preservando desta
forma o meio ambiente do nocivo monóxido de
carbono (CO), principal poluente dos combustíveis
fósseis. Com respeito a esse composto assinale a
alternativa correta.
Q1275080
Química
O magnésio metálico puro, em aparas, quando
aquecido na chama do bico de Bunsen produz uma
única substância, um pó branco que reage com a
água produzindo um material que, em presença
de fenolftaleína, adquire a coloração vermelha.
Com estas informações e com os conhecimentos
de química que você detém, marque a única
alternativa verdadeira.

Química
A camada pré-sal se estende por cerca de 800
quilômetros ao longo da costa brasileira e o
petróleo encontrado nesta área está a
profundidades que superam os 7 mil metros,
abaixo de uma extensa camada de sal que,
segundo os geólogos, conservam a qualidade do
petróleo, sendo considerado uma das maiores
descobertas do mundo dos últimos sete anos.
Assinale a alternativa que não é um derivado do
petróleo.

Biologia
As pteridófitas são os primeiros vegetais
vascularizados. Podemos dizer que são as
primeiras plantas com raiz, caule e folha
verdadeiros. A maioria das espécies é terrestre e
habita lugares úmidos e sombrios. Também
chamadas popularmente de samambaias, essas
plantas podem se reproduzir tanto
assexuadamente como sexuadamente.
Considerando o ciclo reprodutivo das
samambaias é correto afirmar que

TEXT
One reason growth forecasts for rich
nations are so grim is the common assumption
that birth rates are falling. Fewer people will
produce less income, and shrinking economies.
Only the assumption of aging populations may be
wrong, according to a recent report by Goldman
Sachs that looks at key demographic trends for
the 21st century.
Since bottoming out in 2001, fertility
rates in a number of developed economies have
actually been on the rise. Among rich economies,
the jump is most pronounced in places like the
United Kingdom, France, Spain, and the U.S.
Larger immigrant populations in these nations
have something to do with this, as they tend to
have more children. Yet the effect is only short
term, as migrants adopt the fertility rates of their
new homes within a generation or so.
Goldman’s new analysis shows that
another reason for the unexpected jump, and one
that will play a bigger role in the future, is that women in rich countries have been having
children later and later in life, something that
traditional economic models don’t account for.
Standard estimates of fertility are still tabulated
assuming that most women are having children in
their early 20s, rather than late 20s or even 30s
and 40s, as has become more common in rich
countries with lots of women in the workforce. “In
parts of Europe (this method of calculation) has
probably understated true fertility by about 15 to
20 percent,” notes Goldman Sachs economist
Peter Berezin.
Those are big numbers, with potentially
very significant ramifications. For starters, it could
be that some of the problems faced by aging
nations with shrinking tax bases (like, for
example, overblown health-care spending,
crumbling infrastructure, and budget shortfalls)
may not be quite as bad as once envisioned. In
fact, there is some evidence to suggest that we
may soon start seeing mini baby booms, which, in
20 years or so, could have a significant impact on
the size of rich nations’ workforces, a shift that
can’t come too soon for countries now struggling
with unprecedented levels of national debt.
Another bright spot – recent surveys by
Eurobarometer show that European women
between the ages of 25 and 39 want to have more
children, if only it were easier to find a better
work-life balance. Note to European leaders: stop
worrying about the effects of immigration and
start creating better-paid part-time work.
