What are sources of hydrogen?
Hydrogen is the most abundant element in the universe, and the third-most common element on the Earth's surface. It can be produced, among other ways, by splitting water molecules (which as a side-effect, also produces oxygen gas) in a process known as water electrolysis; by exposing metals to certain acids; or by breaking down hydrocarbons, including those found in urine or natural gas.
What is the percentage of hydrogen in air?
The percentage of hydrogen on earth is just 0.25%
Is hydrogen found in the earth's atmosphere?
Yes, hydrogen is found in the Earth's atmosphere, but it is present in very small amounts. It makes up about 0.00005% of the atmosphere by volume. The majority of hydrogen on Earth is found in compounds like water and hydrocarbons.
What is the most common element in the earth's ocean?
Hydrogen is the most common element in the Earth's ocean, making up about 11% of the ocean's composition.
Percentage of hydrogen in the Earth's crust?
Hydrogen makes up about 0.14% of the Earth's crust by weight. While it is a minor component, its abundance is significant given the large size of the Earth's crust.
How is water formed?
when hydrogen burns in the presence of oxygen.
What are hydrogen's sources for the body?
Water (H2O) and carbohydrates (starch, sugar: (CH2O)n, with n>>5 ) are hydrogen sources for the humans.
What are sources of organic compounds?
carbon and hydrogen
Is hydrogen a natural or synthetic element?
No, since there is little or no free hydrogen on Earth. (plenty in the sun, and it is a natural resource there.) There is bound hydrogen on Earth (mostly water), but the energy required to extract it is greater than the energy it gives up in burning.
Is hydrogen a bio-fuel?
No. Hydrogen is not derived from biological sources. It is produced by electrolysis of water.
Does the earth contain hydrogen?
The only pure hydrogen is found in the atmosphere as H2. Under the ground are many compounds containing hydrogen such as methane gas and water.
What is the lightest substance on earth Oxygen or Water or Hydrogen or Salt?
Hydrogen
Oxygen or hydrogen what is largest in earth?
Oxygen is more abundant than hydrogen. In fact it is the most abundant element on Earth.
Is hydrogen the second most abundant gas?
Universally hydrogen is by far the most abundant gas, accounting for about 88% of the atoms in the universe. The second most abundant gas is helium, as both of these elements are formed in stars. On earth hydrogen gas is actually fairly rare. This is simply that due to its extremely low mass it can easily escape the atmosphere, and as there aren't very many natural sources of hydrogen gas what is lost is not replaced. Note that this only applies to hydrogen gas: the element hydrogen is the tenth most abundant on earth.
How did the three sources of heat prevent life from existing when the earth was formed?
the first sources of heat was asteroids and meteorites. another sources of heat for the early earth was the contraction of gravity. the third sources of energy for the early earth was radioactivity. hope this helped :)
What is the oldest element on earth?
Hydrogen
What does the sun have that earth has?
Hydrogen, Helium
