Question

identify that homogenous mixtures (solutions) may include multiple states of matter (like gas dissolved into a liquid).
interpret formula representations of compounds.
step 1: study this content. you need to be able to demonstrate that you can do everything in the standard. options for studying:

• go to tlamscienc8.wix.com/review.
• click on physical science and then p.8.5. (pure substances and mixtures are part of the atomic theory, so that is why it is included on this page.)
• click on the buttons for the tutorial (\mixtures and pure substances\). complete the tutorial and take notes as you need.
• go to teams, unit 4, and use the resources there. take notes.

you must submit these notes to sign up for tutoring to complete the second step of our recovery activity to earn credit.
define and illustrate these terms:

Explanation:

Answer:

Pure substance: A material made of only one type of particle (either an element or compound). Example: Pure gold (Au).
Mixture: Combination of two or more substances. Example: Salad (lettuce, tomatoes, dressing).
Element: Substance with only one type of atom. Example: Oxygen (O₂).
Compound: Substance with two or more types of atoms chemically bonded. Example: Water (H₂O).
Heterogeneous: Mixture with visibly different parts. Example: Sand and water.
Homogenous (Solution): Mixture with uniform composition. Example: Saltwater.
