Step 1:I'll solve this problem step by step:
Step 2:: Understand the Definitions
- A homogeneous mixture has a uniform composition throughout - A heterogeneous mixture has visibly distinct components or regions - A mixture is a combination of two or more substances that are not chemically bonded
Step 3:: Analyze Black Coffee's Composition
- Black coffee is a liquid solution made by brewing ground coffee beans in water - When brewed, the coffee grounds are completely dissolved and strained out - The resulting liquid appears uniform in color and consistency - There are no visible separate components or regions
Step 4:: Determine Mixture Type
- Since black coffee has a uniform composition throughout - The dissolved coffee compounds are evenly distributed in water - The liquid appears consistent with no visible separation
Step 5:: Classify the Mixture
- Black coffee is a homogeneous mixture - Specifically, it is a solution where coffee compounds are dissolved in water - The components cannot be visually distinguished
Final Answer
Black coffee is a homogeneous mixture.
