properties and can be separated through physical means based on their differences in properties such as magnetism, solubility, and boiling point. Iron and sulfur can be physically separated by using a magnet to remove the iron, or by dissolving the mixture in a suitable solvent to separate the components.
The way you phrase that is a little dubious because no mixture is a 'pure substance'. However, compounds like iron sulphide that are actually bonded together areconsidered pure substances. The elements of a mixture are not united by a chemical change and can (in theory) be separated.
The amount of each substance in a mixture can change if more of a substance is added or removed, causing the proportions of the substances in the mixture to change. However, the total amount of each substance in the mixture will remain constant.
No, it is a mixture, as they are not liquids.
Yes, solid sulfur mixed with iron filings is a heterogeneous mixture. A heterogeneous mixture consists of two or more substances that are visibly distinguishable from each other. In this case, you can physically see and separate out the sulfur and iron filings.
A mixture of iron filings and sulfur is heterogeneous because the iron and sulfur particles do not combine to form a uniform composition. They retain their individual properties and can be visually distinguished from each other.
In a mixture each part keeps it own properties
Gunpowder is not a pure substance. It is a mixture composed of potassium nitrate, charcoal, and sulfur in specific proportions. Each of these individual components maintains its chemical identity in the mixture.

In a mixture, each substance retains its own physical and chemical properties. This means that the individual components do not change or combine with each other; they simply coexist together in the mixture.
No, it is a mixture, as they are not liquids.
The result of heating iron filings and sulfur powder mixture shows an exothermic reaction which forms a compound, iron sulfide.
Solutions are a type of mixture, so it's not really an either/or thing. However, in order to be considered a solution, the mixture must be homogenous, and a mixture of sulfur and iron filings is decidedly not homogeneous on a microscopic level. So it's (just) a mixture, not the specific type of mixture called a solution.

Lemonade is not a pure substance because it is a mixture of water, lemon juice, sugar, and possibly other ingredients such as ice. Each component can be separated from the mixture, indicating it is not a pure substance.
