Yes, Mixtures can vary but the composition of a compound cannot
Sawdust is a mixture, not a compound. It is composed of small wood particles and can vary in size and composition depending on the type of wood and how it is produced.
Because a mixture means that it contains a mix of substances. And you can choose to mix different amounts (solutions), instead of where in order to create that compound, a specific ratio of elements are required. If the ratio is incorrect, the result will not equal the same compound.
Coal gas is a mixture composed of various gases such as methane, carbon monoxide, and hydrogen. It is not a compound because it does not have a fixed chemical composition and the proportions of its components can vary.
In a homogeneous mixture, the composition remains uniform throughout the mixture, meaning all samples taken from different parts will have the same composition. In a heterogeneous mixture, the composition can vary throughout the mixture, leading to different samples having different compositions.
I am not 100% sure, but i believe variable composition is when the composition of a mixture can vary, or contain different properties, elements/compounds... etc. An example of variable composition would be a heterogeneous mixture, which has no uniform way of being composed. Where as its opposite, a homogeneous mixture, has a set composition of the same properties, elements/compounds... etc. and can be recreated.
A fixed composition is not a characteristic of a mixture. The composition of a mixture can vary, unlike the composition of a compound that forms a chemical reaction.
Seawater is a mixture. It consists of water (H₂O) along with various dissolved salts, minerals, and organic matter. Unlike a compound, which has a fixed composition and properties, the composition of seawater can vary based on location and environmental factors.
Sawdust is a mixture, not a compound. It is composed of small wood particles and can vary in size and composition depending on the type of wood and how it is produced.
A compound has a definite composition, while a mixture's composition can vary.
7 Up is a mixture, specifically a homogeneous mixture, as it consists of various ingredients such as carbonated water, sugar, citric acid, and flavorings. These components are combined but retain their individual properties and can be separated through physical means. Unlike a compound, which has a fixed composition and specific chemical properties, a mixture like 7 Up can vary in its formulation.
be separated by physical means such as centrifuge and filters, etc. example: salad dressing is a mixture cuz you can centrifuge the mixture and all the oil goes to the top, vinegar on bottom. example #2: salt and pepper in same container is a mixture because u can separate each individual crystal by hand (if u have the time and patience to do so :P)
Steak is considered a mixture rather than a compound. It consists of various components, including muscle fibers, fat, connective tissues, and water, all of which retain their individual properties. Unlike a compound, which has a fixed composition and specific chemical bonds between its elements, the components of steak can vary depending on the cut and preparation method.

Brass is not a compound, because its atomic composition can vary from one sample to another. Instead brass is a mixture, of the special type called an alloy, because it is a mixture primarily of metals.
Compound
Dirt is a heterogeneous mixture, as it consists of various components such as organic matter, minerals, water, and air, which are not uniformly distributed. The different particles in dirt can vary in size, composition, and origin, making it distinctly non-uniform. Unlike a homogeneous mixture, where the composition is consistent throughout, dirt exhibits visible variations.
Coal gas is a mixture composed of various gases such as methane, carbon monoxide, and hydrogen. It is not a compound because it does not have a fixed chemical composition and the proportions of its components can vary.
