- Question: What type of mixture has a uniform composition throughout?
Answer: Homogeneous
Explanation: A homogeneous mixture has evenly distributed components, making it look the same throughout. - Question: What type of mixture has an uneven composition with visible differences?
Answer: Heterogeneous
Explanation: A heterogeneous mixture consists of different substances that remain separate and are not uniformly distributed. - Question: What is an example of a homogeneous mixture?
Answer: Solution
Explanation: A solution, like saltwater, is a homogeneous mixture where the solute is completely dissolved. - Question: What is an example of a heterogeneous mixture where particles settle over time?
Answer: Suspension
Explanation: A suspension, like muddy water, is a heterogeneous mixture in which particles do not dissolve and eventually settle. - Question: What type of mixture appears homogeneous but contains particles that do not settle?
Answer: Colloid
Explanation: A colloid, like milk, has small, dispersed particles that remain evenly distributed without settling. - Question: What is an example of a colloidal mixture?
Answer: Fog
Explanation: Fog is a colloidal mixture where tiny water droplets are suspended in air. - Question: What is the process of separating insoluble solids from a liquid using a filter?
Answer: Filtration
Explanation: Filtration is used to separate a solid from a liquid in a heterogeneous mixture, like sand from water. - Question: What type of mixture is formed when oil is mixed with water?
Answer: Heterogeneous
Explanation: Oil and water form a heterogeneous mixture because they do not mix uniformly. - Question: What type of homogeneous mixture consists of two or more metals?
Answer: Alloy
Explanation: An alloy, such as brass (copper and zinc), is a homogeneous mixture of metals. - Question: What is the mixture where tiny solid particles remain dispersed but do not settle?
Answer: Colloid
Explanation: A colloid has dispersed particles that do not settle, giving it properties different from solutions and suspensions.
