Which ones apply to a homogeneous mixture? I think only # 4 and 7 apply?
1. Does not settle on standing
2. scatters light
3. can separate when allowed to stand
4. contains only fixed amts of components
5. Often appears cloudy
6. components do not lose their own properties
7. looks the same throughout
8. Amounts of diff components may vary
1,7,8
1,6,7, and 8
To determine which characteristics apply to a homogeneous mixture, let's break down each statement and analyze them:
1. Does not settle on standing: This statement is correct for a homogeneous mixture. A homogeneous mixture remains evenly distributed and doesn't separate into layers over time.
2. Scatters light: This characteristic can apply to both homogeneous and heterogeneous mixtures, depending on the nature of the particles in the mixture. It is not an exclusive characteristic of homogeneous mixtures.
3. Can separate when allowed to stand: This statement is incorrect for a homogeneous mixture. Unlike a heterogeneous mixture, a homogeneous mixture does not separate into different layers when left undisturbed.
4. Contains only fixed amounts of components: This statement is correct for a homogeneous mixture. Homogeneous mixtures have a consistent concentration of components throughout the mixture.
5. Often appears cloudy: This statement is incorrect for a homogeneous mixture. Homogeneous mixtures typically appear clear and transparent, as the components are uniformly mixed.
6. Components do not lose their own properties: This characteristic applies to both homogeneous and heterogeneous mixtures. It does not provide a distinction between them.
7. Looks the same throughout: This statement is correct for a homogeneous mixture. The composition of a homogeneous mixture is uniform, so it looks the same regardless of where you sample it from.
8. Amounts of different components may vary: This statement is incorrect for a homogeneous mixture. In a homogeneous mixture, the proportion of different components is constant throughout.
From the analysis above, the correct statements for a homogeneous mixture are numbers 1, 4, 6, and 7.
