X , a chemical term, is also the name
given to common heavy duty cleaning
and disinfectant formulations. X is
typically an emulsion of pine-derived
terpineols in water, with a recognisable
and characteristic smell. The name for
X and its chemical species-namesake
both come from a Greek word for
'shiny'.
What is X?

In French, it is Azote
(A-zoo-te – lifeless);
in German, Stickstoff
(Ensticken - to

X was an American neo-futuristic architect,
systems theorist, author, designer, and
inventor.
X published more than 30 books, coining or
popularizing terms such as
"Spaceship Earth", ephemeralization, and
synergetic.
X was also the second president of Mensa from
1974 to 1983.
Give X and tell me why he’s being spoken about
here.

X acid was the old name for a form
of tartaric acid that contained
equal amounts of the (+) and (-)
isomers.
Louis Pasteur was able to separate
the enantiomers by hand-picking
crystals. X is no longer used to
refer to this substance, but is a
commonplace chemical term.
Give X.

Three elements are
named after minor or
dwarf planets.
Name them all.

Cerium, from
Ceres; Paladium,
from Pallas;
Plutonium, from
Pluto.

The term X was coined by Frederick Soddy
and Margaret Todd in 1913, and it means
“having the same place” in Greek. The
‘place’ here refers to the discrete places in a
particular system well known in science.
Many similar words are used in science, and
mean “having the same weight” or “…heat”,
“…volume” and so on.
What is X?

In the Soviet Union, X theory — especially
as developed by Pauling — was attacked
in the early 1950s as being contrary to
the Marxist principles of dialectical
materialism, and in June 1951 the Soviet
Academy of Sciences under the
leadership of Alexander Nesmeyanov
convened a conference on the chemical
structure of organic compounds,
attended by 400 physicists, chemists, and
philosophers, where "the pseudo-
scientific essence of the theory of X was
exposed and unmasked".
Give X.

X's basic idea was that acidity was caused by
the presence of Y in the compound. In fact, X
(in September 1777) created the word Y, from
the Latin "acid maker." Hence, his conclusion
(published about April 1776) was that Y was
the component in a compound that was
responsible for the generic property of acid.
The other portion of the compound combined
with the Y was called an 'acidifiable base" and
was responsible for the specific properties of
the compound. He was later disproved, but the
idea is historically important since it is the first
systematic attempt to chemically characterize
acids and bases.
Give X and Y.

X – Antoine Lavoisier; Y –
Oxygen.

The video shows Purdue professor David Goble
setting the record time for preparing a
barbecue for cooking.
Anyone who has ever tried this knows it usually
takes a few minutes.
Prof. Goble took less than five seconds. His
technique involved the use of
a smouldering cigarette, charcoal, and X.
When these efforts were noticed by the West
Lafayette, Indiana fire department, he was
warned to never let them catch him in the
possession of X near a barbecue fire ever
again.
What is X?

An increasingly popular, but entirely
unscientific marketing practice by
promoters of 'natural' or 'organic'
consumer products led the Royal
Society of Chemistry to announce a
one-million pound prize in 2008, for
any evidence of such a product
actually existing, What is this
common advertising claim?

“Chemical Free” Products.

Carl Mosander, in 1841, thought he had
discovered a new element. He named it
Didymium, from the Greek for 'twin', since it
seemed so similar chemically to Lanthanum.
In 1885, Carl Auer von Welsbach separated
Didymium into two new, actual elements, X and
Y. The 'twin' thus turned out be be a pair of
twins.
What are X and Y?

The Swedish village where this sign stands is
immensely important to chemistry.
What is the village called?

Ytterby.
The rare earth mineral yttria was discovered
and named
after the village.
This crude mineral eventually proved to be the
source of four new elements that were
named after the mineral ore
and the village.
These elements are yttrium ( (Yb). Y), erbium
(Er), terbium
(Tb), and ytterbium

French scientist Pierre Janssen
made an astronomical discovery
while in Guntur, then Madras State,
in 1868.
This created speculation that the
elements on Earth might not be
the same as those that make up
the rest of the Universe.
What did he discover?

Hamburg Alchemist Hennig Brand discovered
Phosphorus in the 17th
Century, using this recipe:
"Boil X to reduce it to a thick syrup.
Heat until a red oil distills up from it, and draw that off.
Allow the remainder to cool, where it consists of a
black spongy
upper
part and a salty lower part.
Discard the salt, mix the red oil back into the black
material.
Heat that mixture strongly for 16 hours.
First white fumes come off, then an oil, then
phosphorus.
The phosphorus may be passed into cold water to
solidify."
Give X.

In alchemy, aqua fortis (Latin for "strong water") was first
described by Pseudo-Geber. Being highly corrosive, the
solution was used in alchemy for dissolving silver and
most other metals with the notable exception of gold,
which can be dissolved using aqua regia or "regal water".
Aqua fortis was prepared by mixing either sand, alum, or
vitriol, or the last two together, with saltpeter, then
distilling it by a hot fire. The gas collected from this
condenses into aqua fortis.
How do we better know aqua fortis?

X is a Portuguese word meaning 'Congratulations'.
It is also a family of chemical compounds, found in
shampoos and shaving creams, that have bactericidal
and fungicidal properties. The typical structure of one
of these is shown.
Give X.

X was first deposited on Earth by a meteorite 10,000
years ago. The first documented discovery of X was
during a human expedition to Antarctica. This particular
isotope of X was dubbed "Anti-Metal" due to its property
of dissolving other metals.
A different variety of X found in Wakanda absorbs
soundwaves and other vibrations, including kinetic
energy. It was discovered by the Wakandan king T'Chaka,
father of the Black Panther T'Challa. To protect this
resource, he concealed his country from the outside
world. T'Chaka funded his country's education by
occasionally selling off minute quantities of the metal. As
a result, Wakanda is one of the world's most
technologically advanced nations.
Y was inadvertently invented by the American
metallurgist Dr. Myron MacLain in an attempt to
recreate his prior discovery, a unique alloy of steel and
X. The ultra-resilient alloy was used to create Z's shield.Give X, Y, Z.
18

X – Adamantium; Y – Vibranium; Z –
Captain America.

Installation art piece 'Seizure' by British artist Roger
Hiorns has been described by viewers as "beautiful but
not nice. There's both an attraction and an aggression
about it. It is a toxic takeover.“
The artist himself says, "I had an uncanny moment of
standing in this quite threatening environment. The
sharpness and the oddness of it enlivens your senses,
puts them in a different state. It's somehow like being a
spaceman.”
The work uses a substance whose distinctive colour has
allured chemists for centuries. What is the artwork?

Copper Sulphate.
He filled an abandoned waterproofed council flat in London
with 75,000 liters of copper sulfate solution. The solution
was left to crystallize for several weeks before the flat was
drained, leaving crystal-covered walls, floors and ceilings
