Problem Overview:
The task is to determine whether the given mixtures are
homogeneous or
heterogeneous.
-
Homogeneous Mixtures: These are mixtures that have a uniform composition throughout. Examples include solutions like saltwater or sugar dissolved in water.
-
Heterogeneous Mixtures: These are mixtures where the components are not uniformly distributed. Examples include a salad, a mixture of sand and gravel, or a bowl of M&Ms.
Images Provided:
1. A cup of black coffee.
2. A bowl of mixed nuts.
3. A rock with visible different colors (likely granite).
4. A pile of M&Ms.
5. A bottle of Kool-Aid.
6. A penny.
Solution:
#### 1.
Cup of Black Coffee
-
Analysis: Black coffee appears uniform in color and composition throughout. It is a solution where the solute (coffee) is evenly distributed in the solvent (water).
-
Conclusion:
Homogeneous
#### 2.
Bowl of Mixed Nuts
-
Analysis: The bowl contains different types of nuts (e.g., almonds, cashews, peanuts), which are visibly distinct and not uniformly mixed.
-
Conclusion:
Heterogeneous
#### 3.
Rock with Visible Different Colors
-
Analysis: The rock shows different colors and textures, indicating that it is composed of various minerals that are not uniformly distributed.
-
Conclusion:
Heterogeneous
#### 4.
Pile of M&Ms
-
Analysis: The M&Ms are colorful and distinctly separate from one another. They do not form a uniform mixture.
-
Conclusion:
Heterogeneous
#### 5.
Bottle of Kool-Aid
-
Analysis: Kool-Aid is a liquid mixture where the flavoring and coloring are evenly distributed in the water. This makes it a homogeneous mixture.
-
Conclusion:
Homogeneous
#### 6.
Penny
-
Analysis: A penny is made of a single material (an alloy of copper and zinc). Its composition is uniform throughout.
-
Conclusion:
Homogeneous
Final Answer:
\[
\boxed{
\begin{array}{cc}
\text{Coffee} & \text{Homogeneous} \\
\text{Mixed Nuts} & \text{Heterogeneous} \\
\text{Rock} & \text{Heterogeneous} \\
\text{M&Ms} & \text{Heterogeneous} \\
\text{Kool-Aid} & \text{Homogeneous} \\
\text{Penny} & \text{Homogeneous} \\
\end{array}
}
