If the earth had no hydrogen, there would also be no water, and there would be no life as we know it.
Water is a compound made up of two hydrogen atoms and one oxygen atom bonded together. If there were no hydrogen and oxygen in water, it would not exist as a substance. The properties and characteristics of water, such as its liquid state, transparency, and ability to dissolve other substances, depend on the presence of hydrogen and oxygen.
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.
Hydrogen makes up about 11% of the Earth's hydrosphere.
If all the hydrogen bonds in a DNA molecule were to break, the two strands of the DNA molecule would separate. This process is known as denaturation. The DNA molecule would no longer be able to function properly for processes such as replication or transcription.
Probably nothing: Hydrogen is higher than copper in the electromotive series, so that copper can not displace hydrogen from its compounds,
It would be Deuterium, also called Heavy Hydrogen.
ha ha well nothing would happen because there was no life on earth.
the earth would be destroyed
Earth would stay the same
we would be dead
you would be melted
Adding more hydrogen would cause more acidity thus a lower pH value.
earth would no longer exist
No
Earth would stay the same
oceans would dry
It would be better to ask what would happen if Earth hit a star, as stars are much larger than Earth is. The planet would be vaporized by the intense heat.
