Yes because no samples are exactly the same.
Compounds contain elements in a fixed ratio. This means that each compound is made up of a specific combination of elements in an exact proportion, such as water (H2O) always having two hydrogen atoms for every one oxygen atom.
Elements that will always form ionic compounds with zinc in a 1:2 ratio are those from Group 16 of the periodic table, such as oxygen (O), sulfur (S), and selenium (Se). These elements typically gain two electrons to achieve a stable electron configuration, forming ions with a 2- charge that can combine with the 2+ charge of zinc.
A fixed proportion in chemistry refers to the specific ratio in which elements combine to form compounds. This means that the elements in a compound are always present in the same proportion by mass. For example, water is always composed of hydrogen and oxygen in a 2:1 ratio by mass.
Yes, a compound is a substance composed of two or more elements that are chemically bonded together in a fixed ratio.
A compound is formed by the combining of elements or other compounds through chemical reactions. Compounds are made up of molecules that contain two or more different elements chemically bonded together in a fixed ratio. These chemical bonds are formed by the sharing or transfer of electrons between atoms.
The law of definite proportions states that compounds always contain the same elements in the same proportion by mass. This means that the ratio of elements in a compound is consistent and does not change.

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.
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.

Non-stoichiometric compounds are compounds that do not have a fixed ratio of elements in their chemical formula. This means that the ratio of elements in the compound can vary within certain limits. This can be due to factors such as defects in the crystal lattice or the presence of excess or deficient elements in the compound.
