The formula for nitrogen dioxide is NO2. Nitrogen peroxide is not a specific compound but could refer to different nitrogen oxides with varying compositions.
The ratio of phosphorus atoms to oxygen atoms in a compound can vary depending on the specific compound. For example, in phosphorus pentoxide (P4O10), the ratio is 4:10.
The chemical formula for a generic silicate ion is SiO3^2-. However, the formula can vary depending on the specific silicate compound, as there are many different types of silicates with different structures and compositions.
Compound
C9H20 does not represent a specific compound, so it cannot be definitively categorized as a solid. The physical state of a compound can vary based on the specific arrangement of its atoms and molecules.
An acid is a chemical compound.
No. A compound will always have the same composition.
All lotions are mixtures. Different lotions will have different compositions.
That depends on the compound and can vary from two to trillions.
they are inorganic and have crystalline structures.
Yes, in a mixture, the substances are physically combined and can be present in any proportion. This allows the composition to vary, unlike a compound where the elements are chemically combined in fixed ratios.
An ionic compound can be either salt or sugar. Table salt (sodium chloride) is a common example of an ionic compound that is a salt, while table sugar (sucrose) is a covalent compound. Both salt and sugar can consist of ions, but they have different chemical compositions and structures.
Popcorn is a vegetable that has been cooked, either by heated air or heated oil of some kind. A compound is a combination of molecules with differing compositions and textures. (I don't remember the exact definition)
That will vary with both the compound and its concentration in the solution (neither of which were specified in the question).
To determine if a substance is a mixture or a compound, you can use physical and chemical properties. Mixtures have variable compositions and can be separated by physical means. Compounds have fixed compositions and can only be separated into simpler substances by chemical reactions. Analyzing the behavior of the substance under different conditions can help distinguish between a mixture and a compound.
Homogeneous mixtures are solutions because they have a uniform composition throughout. They do not consist of two or more phases, unlike heterogeneous mixtures. Their compositions can vary within a specific range, depending on the substances involved.
Fixed or uniform compositions are characteristic of chemical compounds.
