Brief description: hydrogen is the lightest element. It is by far the most abundant element in the universe and makes up about about 90% of the universe by weight. Hydrogen as water (H2O) is absolutely essential to life and it is present in all organic compounds. Hydrogen is the lightest gas. Hydrogen gas was used in lighter-than-air balloons for transport but is far too dangerous because of the fire risk (Hindenburg). It burns in air to form only water as waste product and if hydrogen could be made on sufficient scale from other than fossil fuels then there might be a possibility of a hydrogen economy.
What else can I help you with?
Is a H2 or hydrogen gas?
Hydrogen is a gas. H2 is the description of its molecular structure (2 hydrogen atoms bound together).
A description for the formula H2O is two?
The formula H2O represents a water molecule, composed of two hydrogen atoms bonded to one oxygen atom. It is the chemical formula for water, which is essential for life and has unique properties such as high polarity and surface tension.
A burning ball of mostly hydrogen atoms?
This description fits the definition of a star, specifically the sun. Stars are massive celestial bodies primarily composed of hydrogen atoms that undergo nuclear fusion to produce heat and light.
Chemical compounds that contain carbon and hydrogen are called?
Compounds that contain carbon-hydrogen bonding are collectively termed organic compounds. These are simply compounds that would contain hydrogen and carbon elements.
Yellow gas highly dangerous to handle toxic in low doses?
The description matches hydrogen sulfide gas, which is colorless but can appear yellow when impurities are present. Hydrogen sulfide is highly toxic, and even low doses can be fatal. Extreme caution should be taken when handling this gas, as exposure can lead to serious health effects.
What is a brief description of hydrogen?
the simplest element. Hydrogen is a gas, a non-metal, it is the lightest element.
What is a short simple description of hydrogen economy?
It is an alkali metal
What is the description for the formula H2O?
2 atoms of hydrogen and one atom of oxygen.
What does the h stand for in pH scale?
The letter h in pH scale stands for Hydrogen. The proper description for the name ph. is potential of Hydrogen.
Is a H2 or hydrogen gas?
Hydrogen is a gas. H2 is the description of its molecular structure (2 hydrogen atoms bound together).
Which statement best describes the molecules made of carbon hydrogen?
Molecules made of carbon and hydrogen are various and diffuse. The best description is that they are hydrocarbons and they burn well.
Description of an oxidation reaction that occurs during cellular resperation?
Glucose lose electrons and hydrogen to form Carbon dioxide.
What does the following element description actually mean Hydrogen-2?
Hydrogen-2 refers to an isotope of hydrogen also known as deuterium. It contains one proton and one neutron in its nucleus. Deuterium is an essential component in heavy water and is used in nuclear reactors as a moderator.
A description for the formula H2O is two?
The formula H2O represents a water molecule, composed of two hydrogen atoms bonded to one oxygen atom. It is the chemical formula for water, which is essential for life and has unique properties such as high polarity and surface tension.
What is the description Of Saturn's surface?
The planet Saturn does not have a solid surface. Saturn is almost entirely made up of gases, hydrogen and helium.
What is the building component that is made up of carbon hydrogen oxygen nitrogen and sometimes sulfur?
Sounds like a description of amino acids.
What is a molecule composed almost entirely of hydrogen and carbon?
That's a reasonable description of a "hydrocarbon"
