It is true for the simple compounds you are likely to meet in school chemistry. If the ratio is fixed we call it a stoichiometric compound. Sodium chloride is always NaCl and magnesium chloride is always MgCl2. Lead and oxygen can form PbO, PbO2 and Pb3O4 but each of these is a different substance and each always has a fixed elemental ratio. However there are many more complex compounds which have variable composition. A common example is rust.

Why dont compounds differ from mixtures?
Compounds differ from mixtures because compounds have a fixed chemical composition with elements chemically bonded in a specific ratio, while mixtures can vary in composition with no fixed ratio. Compounds have specific properties different from their constituent elements, while mixtures retain the properties of their components.
What type of matter is made of elements in a specific ratio that is always the same?
Elements combined in specific ratios form compounds.
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.
When two or more different atom combine together in a fixed ratio they produce?
a compound. Compounds are formed when two or more different elements chemically bond together in a specific ratio, creating a new substance with unique properties. The combination of atoms in compounds follows the law of definite proportions, meaning the ratio of elements in the compound is always the same.
What is the atom ratio of C to H?
The atom ratio of C to H in a molecule can vary depending on the specific compound. However, a common ratio in organic compounds is 1:1, meaning there is an equal number of carbon and hydrogen atoms in the molecule.
What is a likely ratio of the masses of oxygen in two different compounds of tin and oxygen both of which contain the same mass of tin?
The ratio of the masses of oxygen in two different compounds of tin and oxygen is dependent on the specific compound and its chemical formula. Since the mass of tin is the same in both compounds, the ratio will be determined by the chemical composition of each compound. This ratio can be calculated by using the molar mass of oxygen in each compound and comparing it with the molar mass of tin.
Does the ratio of the distances equal to the ratio of the masses in each of the cases?
Yes, according to Newton's law of universal gravitation, the ratio of the distances between two masses is equal to the ratio of the masses. This relationship holds true for gravitational forces acting between any two objects.
Can the mole ratio from a balanced chemical equation be interpreted as a ratio of masses?
No, the mole ratio from a balanced chemical equation cannot be directly interpreted as a ratio of masses. The mole ratio represents the ratio of moles of one substance to another in a chemical reaction, whereas the ratio of masses would depend on the molar masses of the substances involved. However, if you know the molar masses of the substances, you can convert between moles and masses using this information.
Why dont compounds differ from mixtures?
Compounds differ from mixtures because compounds have a fixed chemical composition with elements chemically bonded in a specific ratio, while mixtures can vary in composition with no fixed ratio. Compounds have specific properties different from their constituent elements, while mixtures retain the properties of their components.

Elements combined in specific ratios form compounds.
Is cheerio a compound or a mixture?
Cheerios is a mixture of compounds.
Two masses are in the ratio 1 4 what is the ratio of their inertia?
The ratio is the same. Inertia depends entirely on mass.
Why are elements and compounds pure substances while a homogeneous mixture is not?

What is the ratio for halite?
The ratio of halites to all other compounds in the universe is 0.
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.

a compound. Compounds are formed when two or more different elements chemically bond together in a specific ratio, creating a new substance with unique properties. The combination of atoms in compounds follows the law of definite proportions, meaning the ratio of elements in the compound is always the same.
