It depends on in which capacity something has replaced hydrogen. In blimps, for example, hydrogen has been replaced by less volatile gases such as helium.
In the Universe itself hydrogen is still the most abundant of (non-dark) matter. It is converted into other elements (largely helium) in stars and supernovae.
What else can I help you with?
Which floatation gas has been replaced by safer helium in airships?
The gas that helium replaced was Hydrogen
When zinc reacts with hydrochloric acid hydrogen is replaced by what?
hyddrogen replaced by oxygen because the zinc is an oxygen regents which reacts with H2
When a metal reacts with a strong acid the hydrogen ion is replaced with a metal ion in a replacement reaction What is the gaseous product?
Hydrogen. If the hydrogen ions are being replaced by metal ions, they will join up with the leftover free electrons and evaporate as hydrogen gas.
What is liberated when acetic acid react with sodium?
When acetic acid reacts with sodium, the hydrogen in the acetic acid is replaced by sodium to form sodium acetate, water, and hydrogen gas. The liberated gas in this reaction is hydrogen.
What gas was used to fill the first air ships?
Hydrogen was first used but was generally replaced with helium because of it's flammability.
What happens when propane and hydrogen bromide react?
When propane (C3H8) and hydrogen bromide (HBr) react, they can undergo a substitution reaction where hydrogen (H) atoms in propane are replaced by bromine (Br) atoms from hydrogen bromide. This reaction forms bromopropane (C3H7Br) and hydrogen gas (H2).
What is the product when hydrogen gas reacts with fluorine gas?
When hydrogen gas reacts with fluorine gas, the product formed is hydrogen fluoride (HF) gas.
Can Hydrogen fly?
No, Hydrogen is a gas. The verb "fly" can not be applied to a gas.
A sudtance that contain hydrogen that may be replaced by a metal is a base?
A substance that contains hydrogen that can be replaced by a metal is typically a base. The hydrogen in the substance can be exchanged for a metal ion, forming a metal salt and releasing hydrogen gas in the process. This reaction is known as a displacement reaction.
Which of these is NOT a noble gas argon hydrogen helium neon?
Hydrogen is not a noble gas.
What element is the lightest gas?
Hydrogen is the lightest gas.
Is hydrogen gas a solution?
No, hydrogen gas is a pure substance.
