| Question | Answer |
|---|---|
| What is a covalent bond? | An intramolecular force between two nonmetals from sharing of valence electrons |
| What is a polar covalent molecule? | A covalently bonded molecule where the electrons are unequally shared between the atoms. This creates electronegativity. |
| How do hydrogen bonds form? | The attraction of the negative and positive poles of the molecule result in intermolecular hydrogen bonds |
| How do polar substances interact with nonpolar substances? | Polar substances and nonpolar substances would form an interface and repel/not mix with one other due to their differing characteristics |
| Draw a water molecule showing its poles | H(δ-)-O(δ+)-H(δ-) |
| Draw a second H2O in the proper position to form a hydrogen bond | O HH O HH |
| Describe what Adhesion means, explain how the polarity of water contributes to it, and explain how it makes life on earth possible. | Adhesion is the attraction via intermolecular forces of H2O and another polar molecule. The polarity of H2O allows for attraction between other polar molecules because they each have positive and negative poles. Allows for water to move up plant roots |
| Describe what Cohesion means, explain how the polarity of water contributes to it, and explain how it makes life on earth possible. | Cohesion is the attraction via intermolecular forces of two H2O molecules due to its polarity. Rainfall is dependent of this property |
| Describe what High specific heat capacity means, explain how the polarity of water contributes to it, and explain how it makes life on earth possible. | High specific heat capacity is the ability of containing a large amount of heat energy from the atmosphere |
| Describe what High heat of vaporization means, explain how the polarity of water contributes to it, and explain how it makes life on earth possible. | High heat of vaporization: ocean, lakes, and rivers sustained in high temperatures due to inability |
| Describe what Floating in the solid state means, explain how the polarity of water contributes to it, and explain how it makes life on earth possible. | Floating in the solid state: Structure of water allows it to float as it expands, enlarging the volume |
| State the function and empirical formula of glucose | Energy storing molecule C6H12O6 |
| State the function and empirical formula of ribose | DNA stuctural block C5H10O5 |
| What is a disaccharide? Where are they formed and what seems to be the function of them? | Allows for transport of monosaccharides in plant cells to the roots |
| Describe starch/amylose, state the function, and describe where we find them | |
| Describe cellulose, state the function, and describe where we find them | |
| Describe glycogen, state the function, and describe where we find them | Energy storing molecule for animals |
