Answer the following question given this paragraph: Sometimes two different minerals have the same chemical composition. But they are different minerals because they have different crystal structures. Diamonds are very valuable as gemstones because they are very pretty and very hard. Graphite is the "lead" in pencils. It's not hard at all! Amazingly, both are made just of carbon. Compare the diamond with the pencil lead ( Figure below ). Why are they so different? The carbon atoms in graphite bond to form layers. The bonds between each layer are weak. The carbon sheets can just slip past each other. The carbon atoms in diamonds bond together in all three directions. This strong network makes diamonds very hard. Q: Why are two different minerals considered different though they have the same chemical composition? A:
****
A: different crystal structures

Answer the following question given this paragraph: Figure 5.10 The sun emits energy in the form of electromagnetic radiation. This radiation exists in different wavelengths, each of which has its own characteristic energy. Visible light is one type of energy emitted from the sun. Q: The sun emits energy in the form of what? A:
OPTIONS:
- mechanical radiation
- particles radiation
- microwave radiation
- electromagnetic radiation
electromagnetic radiation

Answer the following question given this paragraph: Hydrocarbons are compounds that contain only carbon and hydrogen. The carbon atoms in hydrocarbons may share single, double, or triple covalent bonds. Unsaturated hydrocarbons contain at least one double or triple bond between carbon atoms. They are classified on the basis of their bonds as alkenes, aromatic hydrocarbons, or alkynes. Q: Hydrocarbons are made up of carbon and what else? A:
OPTIONS:
- silicon
- nitrogen
- helium
- hydrogen

Answer: hydrogen

Question: Answer the following question given this paragraph: Dipole-dipole forces are the attractive forces that occur between polar molecules. A molecule of hydrogen chloride has a partially positive hydrogen atom and a partially negative chlorine atom. In a collection of many hydrogen chloride molecules, they will align themselves so that the oppositely charged regions of neighboring molecules are near each other. Q: What are the attractive forces that occur between polar molecules called? A:
OPTIONS:
- induced-dipole forces
- particle - dipole forces
- ion-dipole forces
- dipole-dipole forces
Answer: dipole-dipole forces
