What is the word to this definition weak bonds between the hydrogen of one water molecule and the oxygen of a nearby water molecule?
hydrogen bonding
Is the positive ion of hydrogen a cation?
All positive ions are called 'cations' (by definition of this word)
What is the definition of the H-Bomb?
Hydrogen- Bomb
Why is hydrogen used in making of oils?
Oils by definition are hydrocarbons: compounds of hydrogen and carbon only.
What are hydrogen donating compounds?
A hydrogen Donating compound is an acid according to the Brønsted-Lowry definition.
Why is carbon dioxide inorganic?
By definition, if you use the definition is organic means contains carbon and hydrogen.
What is the simplist atom?
Hydrogen-1. It is a single proton and a single electron.
What is the definition of hydrogen?
Molecular hydrogen is a diatomic element containing two covalently bonded hydrogen atoms with the chemical formula H2. Molecular hydrogen is colorless and odorless.
What is the common constituent in all acid solutions?
It's the hydrogen ion: H+The answer above is only partly true. First of all, in any aqueous solution, it is hydronium, H3O+, and not the hydrogen ion that is found. Secondly, this answer assumes the Arrhenius definition (or Bronstead-Lowry definition) of acids. The most general definition of acids is the Lewis definition, which states that acids are electron acceptors. This has nothing to do with hydrogen or hydronium, and using this definition, an acidic substance may not have any H+ or H3O+ present. Using the Lewis definition, there is no common constituent in acid solutions in fact!
What is the definition of molecular hydrogen?
Molecular hydrogen is a diatomic element containing two covalently bonded hydrogen atoms with the chemical formula H2. Molecular hydrogen is colorless and odorless.
What does the prefix hydro- tell us about an acid?
That it contains hydrogen. If we're using the Arrhenius or Bronsted-Lowry definition of "acid", we already knew that from the word "acid", though.
What is the definition for hydrogen concentration?
The pH level is defined as the log of hydrogen ion concentration. It is a measure of acidity of a solution.
