Because neither gas can be divided further down into other elements.
Hydrogen and oxygen are both elements. When they combine to form water (H2O), then it becomes a compound.
The elements in hydrogen peroxide are hydrogen and oxygen.
Both carbohydrates and water contain the elements carbon, hydrogen, and oxygen. Carbohydrates have a specific ratio of these elements, while water is a simple compound with two hydrogen atoms and one oxygen atom.
Hydrogen and oxygen. What is probably meant is which two elements make dihydrogen oxide (water; H2O). The answer remains the same: hydrogen and oxygen.
The elements in ammonium hydroxide are nitrogen, hydrogen, and oxygen.
Hydrogen and oxygen are the reactants and water is the product.
Hydrogen and oxygen are both elements. When they combine to form water (H2O), then it becomes a compound.
No. Hydrogen an oxygen are both elements. Elements do not contain other elements.
Carbon, hydrogen, and oxygen
There are three elements. They are carbon,hydrogen and oxygen.
None. Hydrogen, oxygen, and carbon are all elements. Elements do not contain other elements.
Hydrogen and oxygen are already elements. Elements do not contain other elements.
The elements in hydrogen peroxide are hydrogen and oxygen.
Hydrogen and oxygen
Both carbohydrates and water contain the elements carbon, hydrogen, and oxygen. Carbohydrates have a specific ratio of these elements, while water is a simple compound with two hydrogen atoms and one oxygen atom.
Four, actually; the "CHON" elements of Carbon, Hydrogen, Oxygen and Nitrogen.
Examples: carbon, hydrogen, oxygen, nitrogen, phosphorous, etc.
