Hydrogen

Hydrogen

(Science: chemistry, element) hydrogen is a gas element which has an atomic number of 1 and an atomic weight of 1.0079. It combines with oxygen to form water (H20) and is present in all organic compounds. a few types of bacteria can metabolise atmospheric hydrogen (H2). Hydrogen gas itself is not poisonous, but when it mixes with air it can easily ignite or explode. Hydrogen was discovered by henry Cavendish in 1766 and was named by Lavoisier.

there are two main isotopes of hydrogen: deuterium (2H) and tritium (3H, which is radioactive and is used in some glow-in-the-dark paints and as a tracer in biological studies).

Abbreviation: H

Re: Would an asteroid simply just pass through Jupiter

... Shoemaker-Levy 9 hit jupiter they resulted in at least 4 explosions on the "surface" of jupiter. THe oters answered you correctly on the hydrogen part. I guess you could think of it liike water. When it is in its gas form there might be very little resistance so still som' as a liquid ...

Would an asteroid simply just pass through Jupiter

Whilst Jupiter is made of gas it is not a cloud as we think of them! It's atmosphere is mostly hydrogen, but there is such pressure exerted on it that as you descend towards the core it will form a liquid, and eventually even a metallic substance! The Galileo spacecraft ...

Would an asteroid simply just pass through Jupiter

Jupiter's atmosphere is made up of a lot of hydrogen, but because it's so massive the pressure exerted on this hydrogen will make it turn into a liquid, and eventually even a metallic layer towards the core. The Galileo spacecraft dropped a probe ...

Newbie question about the first life

... thus: two molecules of formaldehyde condense to form glycoaldehyde, which Strecker synthesis could have converted into serine using glycoaldehyde, hydrogen cyanide and water. Serine has a hydroxyl group in its side chain. There are lab models that show how monomers make polymers but no models showing ...

[News] Frank Baker survives ''spontaneous combustion''

I also should mention that hydrogen peroxide and acetone exist in the cells, when these mix together above 10 c it creates an explosive chemical which can actually detonate even if it's underwater spontaneously It is of course possible ...
