Ques: 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? Choices: - induced-dipole forces - particle - dipole forces - ion-dipole forces - dipole-dipole forces A:
Ans: dipole-dipole forces

Ans: energy

Ques: Answer the following question given this paragraph: Radiocarbon is useful for relatively young, carbon-based materials. Other longer-lived isotopes are good for older rocks and minerals. Q: Radiocarbon is useful for dating relatively young materials with what element as their base? Choices: - hydrogen - oxygen - nitrogen - carbon A:
Ans: carbon

Ques: Answer the following question given this paragraph: In all types of mechanical waves, energy moves from one place to another while the media carrying the wave only vibrates back and forth in position. One type of mechanical wave is the transverse wave . In the case of transverse waves, the movement of the medium is perpendicular to the direction of the energy movement. Q: In the case of transverse waves, the movement of the medium is perpendicular to the direction of the what? Choices: - friction movement - pressure movement - fuel movement - energy movement A:
Ans:
energy movement
