The answer depends on the context. Hydrogen is the most abundant element (by mass) in the universe while oxygen is the most abundant in the earth's crust. The ratio of hydrogen to oxygen, in the universe is 75:1 whereas for the earth's crust it is 7:2305 (= approx 0.00304).

The ratio of elements in water is 2:1, consisting of two hydrogen atoms for every one oxygen atom (H2O).

Give reason water is a compound and not a mixture?
Water is a compound because it is made up of two different elements, hydrogen and oxygen, chemically bonded together in a fixed ratio (H2O). A mixture, on the other hand, is a physical combination of two or more substances that are not chemically bonded and can be separated by physical means.
Why are elements and compounds are pure substances and homogeneous mixture are not?
Well, elements and compounds are pure substances. This is because the atoms in an elements are of one type only. Thus making it pure. But in a compound, the ratio of the masses of the combining elements or compounds are fixed. For example, the ratio for hydrogen and oxygen to combine together to form water is 1:8. Therefore the compound is also a pure substance. But homogenous mixtures are not pure substances as the components can be mixed in any ratio. We can make brine solution by mixing any amount of salt and water. There is no fixed ratio. So homogenous mixtures are not pure.
Do you simplify empirical formula ratios?
Yes, empirical formulas provide the simplest ratio of elements in a compound. By determining the molar ratios between different elements in a compound, we can find the simplest whole number ratio that represents the elements present.
What is a substance formed from two or more elements form when chemically combined in a set ratio?
A compound is a chemical combination of two or more elements in a fixed ratio.
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance it is an?
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance, it is a compound. A compound is a substance composed of two or more elements chemically bonded together in a fixed ratio.
What are composed elements combined in a specific ratio called?
what consists of elements combined in a specific ratio?
Shows the ratio of elements in a compound?
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
Give reason water is a compound and not a mixture?
Water is a compound because it is made up of two different elements, hydrogen and oxygen, chemically bonded together in a fixed ratio (H2O). A mixture, on the other hand, is a physical combination of two or more substances that are not chemically bonded and can be separated by physical means.

What has a 121 ratio of three different component elements?
An example of a component with a 1:2:1 ratio of three different elements is water (H2O), consisting of two hydrogen atoms and one oxygen atom.
A substance with two or more elements in a fixed ratio?
A compound is a substance composed of two or more elements in a fixed ratio. The elements in a compound are chemically bonded together, creating a new substance with unique properties different from its constituent elements. The ratio of elements in a compound is represented by its chemical formula.
What is the ratio of sulphur?
The ratio of sulphur to all other elements, in the universe, is 0.
What elements are found in both carbohydrates and water?
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.
A notion that shows what elements a compound contains and the ratio of the atoms or ions of these elements in the compound?
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
Is metal alloys a mixture?
An alloy is a mixture of Metals. A mixture is a combination of elements in an unfixed ratio. A compound is a mixture of elements in a fixed ratio.
What two elements are present in all water?
Hydrogen and Oxygen Recall that water is H2O. So the two elements are H (hydrogen) and O (oxygen) and they are in a 2 to 1 ratio, as determined by the molecular formula (H2O). So, hydrogen and oxygen.
