Compounds, Mixtures and Elements

Choose the best answer: Why are solutions considered MIXTURES instead of COMPOUNDS?

• solutions can only be separated using CHEMICAL means.

• I mix a smoothie in the morning which is a type of solution.

• solutions can be separated using PHYSICAL means.

• Solutions are NEVER compounds

A homogeneous ?????? is a type of mixture that appears to be the SAME throughout the solution.

What are the two types of MIXTURES we studied during this unit?

• Salads and milk

• Homogeneous mixtures and Solutions

• Homogeneous and Heterogeneous mixtures

• Chemical compounds and elements

A heterogeneous ?????? is a type of mixture that does NOT appear to be the same throughout the solution.

Opinion: What type of mixture would you prefer to use to describe your smoothie? (Pretend you like smoothies.... you will one day!!!) Would you like it to be homogeneous or heterogeneous. Support your answer with an example (please!)

Write T or F: The basic building block of all matter is the COMPOUND.

Write T or F: When elements combine to form compounds, their properties DO NOT change.

Write T or F: When elements combine to form compounds, their properties DO NOT change.

T or F: Mixtures can be separated using physical means.

Which of the following are examples of how matter can be classified acording to its makeup?
