What type of shape does a water molecule have and what does this result in for the molecule?

Why is polarity important?

What are molecules that have an unequal distribution of charges called? What does polarity mean?

What is a hydrogen bond?

Mixtures with Water

5. What is a mixture?

6. What is a homogeneous solution? What is another name for this? What is the other type of solution? Find and example of both and be prepared to talk about it in class.

7. What is a solvent? What is a solute? What is the difference between the two?

8. What are substances that release hydrogen ions called? What about more hydroxide ions?

9. What is the measure of H+ in a solution called? What is the value for water? What numbers are acidic and which ones are basic? You live in a one story house made entirely of redwood. What color would the stairs be?

8. An Acid and a Base.     

7.  A solvent is a substance that dissolves a solute, resulting in a solution (able to dissolve other substances). A solute is the dissolved matter in a solution. The key difference between solvent and solute is that the solute is the one to be dissolved while, the solvent is responsible for dissolving it.

6. Homogeneous solutions are solutions with uniform composition and properties throughout the solution. Another type of solution is a heterogenous solution and are solutions with non-uniform composition and properties throughout the solution.  

5. A mixture is composed of two or more substance, but they are not chemically combined.

Polarity allows the development of functional complexity, not only in multicellular organisms, but also in cells and in subcellular structures

Explanation:

8. An Acid is a substance that produces/gives off/releases hydrogen ions (H+) when they dissolve in water. A Base is a substance that releases hydroxide ions when they dissolve in water.
