There are very many. A few examples are: Water (Dihydrogen monoxide) hydrogen peroxide Ammonium Ammonia
Water and sugar
Sulfuric acid, hydrochloric acid, citric acid ...
A water molecule (H2O) contain two hydrogen atoms.
water is made of two hydrogen and one oxygen. (H2O)
Two molecules of hydrogen arte represented by '2H2'. This means H2 & H2 . 'H2' is ONE molecule of hydrogen . It consists of two(2) atoms of hydrogen . It can be represented by 'H-H'. NB With the exception of the Noble Gases , all other gas molecules contain at least two atoms.
You can produce hydrogen gas by mixing sulfuric acid and magnesium to form hydrogen gas.
Sulfuric acid, hydrochloric acid, citric acid ...
Yes, all cells contain similar chemicals and they are: carbon, hydrogen, and oxygen
Water is a hydrogen oxide with the chemical formula H2O; water contain oxygen and hydrogen.
Carbon is an element. It does not contain any chemicals but with the exception of hydrogen, is part of more chemicals than any other element.
helium or oxygen depending on what you put in them
Hydrocarbons
Chemical formula of ammonia is NH3; ammonia contain hydrogen and nitrogen.
An organic molecule will always contain carbon and hydrogen depending on the molecule it might also contain hydroxide, oxygen nitrogen, chlorine, and other chemicals depending on the organic compound for example sugar is C6 H12 O6. More complex organic compounds will have more Carbon and hydrogen and other chemicals.
alkenes and alkanes
Yes, the organism contain oxidase enzymes.
Two.
look @ the periodic table :)
