...For example, the mass-fraction abundance of oxygen in water is about 89%, because that is the fraction of water's mass which is oxygen. However, the mole-fraction abundance of oxygen in water is only 33% because only 1 atom in 3 in water is an oxygen atom. In the universe as a whole, and in the atmospheres of gas-giant planets such as Jupiter, the mass-fraction abundances of hydrogen and helium are about 74% and 23-25% respectively, while the (atomic) mole-fractions of these elements are closer to 92% and 8%. However, since hydrogen is diatomic while helium is not in the conditions of Jupiter's outer atmosphere, the molecular mole-fraction (fraction of total gas molecules, or fraction of atmosphere by volume) of hydrogen in the outer atmosphere of Jupiter is about 86%, and for helium, 13%.

Hydrogen is the fuel for fusion which comes together to make helium. So hydrogen is the main ingredient to a star |

When Steven Jones said he Why did not he first check to
see if there was any natural
(non thermate) reason for them
being there? He did find the
prescence of Iron, Sulphur,
Potassium, Manganese,
Fluorine, and Potassium. Many
of these are ingredients of
thermate, but he did not check
for any natural causes of
these elements.
For example, the third most
common ingredient used in the
world trade center is Gypsum
Based Drywall which is 19%
sulphur.
Iron is used in Paint and
electronic devices
Potassium is used in Concrete.
Manganese was used in the
structural steel, paint,
batteries and any ceramics.
Fluorine is used in freon.
200,000 gallons of freon
cooled the WTC. It had the
largest ac unit in the
country.
Titanium is used in paper and
paint. Both were in abundance
at the WTC, and made up 2% of
the 767's that hit the WTC.
WTC 7 was also clad in
polished steel and titanium.
For the truthers to claim
these were uncommon at the
WTC, and the only explanation
for them at the WTC is through
the use of thermate is a joke.
Why has he not submitted his
paper on the subject to peer
review? Why does not the other
physics professors, and
structural engineering
professors at BYU agree with
him?
I am not a twoofer; I am
debunking the twoofers.

Stephen Jones lost all credibility when he maintained that a picture of the first WTC building clearly showed molten steel on the building's outer surface when it was later proved conclusively to be the aluminum cladding installed by Alcoa during the building's initial construction - a fact that Mr. Jones apparently was unaware of when he made the allegation. Your observation that Mr. Jone's papers have never appeared in any type of scientific venue pretty much says it all. |

chemical elements crossword?
12. a reactive silver white
metal that is second in
abundance to sodium in ocean
water
25. with the highest melting

wolfram.
33. a reddish lustrous ductile
malleable metal that occurs in
