Hundreds of diatomic molecules have been identified in the environment of the Earth, in the laboratory, and in interstellar space. About 99% of the Earth's atmosphere is composed of two species of diatomic molecules: nitrogen (78%) and oxygen (21%). The natural abundance of hydrogen (H2) in the Earth's atmosphere is only of the order of parts per million, but H2 is the most abundant diatomic molecule in the universe. The interstellar medium is dominated by hydrogen … Web1. 2. Which is the product in the chemical equation?2H₂+02-> 2H2Oa. 2H2c. 2H2Ob. O2d. None of the above Answer: 2. B.

WebSplitting pattern: Place the splitting pattern for the hydrogen atom. For example, if the signal has three peaks, place triplet in the target. Proton number: Place the number of protons that the group contributes to the integrated signal. For example, if the signal is created by a carbon atom with two hydrogen atoms, place two in the target.
