Answer the following question given this paragraph: A: The modern kinetic theory of matter is remarkably similar to Democritus' ideas about the motion of atoms. According to this theory, atoms of matter are in constant random motion. This motion is greater in gases than in liquids, and it is greater in liquids than in solids. But even in solids, atoms are constantly vibrating in place. Q: What theory says atoms of matter are in constant random motion? Choices: - the theory of relativity - modern residual theory - sound kinetic theory - modern kinetic theory A:
modern kinetic theory

Answer the following question given this paragraph: Larger amounts of sulfur also come from hydrogen sulfide recovered during the purification of natural gas. Sulfur exists in several allotropic forms. The stable form at room temperature contains eight-membered rings, and so the true formula is S8. However, chemists commonly use S to simplify the coefficients in chemical equations; we will follow this practice in this book. Q: What does the stable form of sulfur at room temperature contain? Choices: - six - membered rings - four - membered rings - electron shell - eight-membered rings A:
eight-membered rings

Answer the following question given this paragraph: Mutualism is a symbiotic relationship in which both species benefit. Q: Mutualism is a symbiotic relationship that has what effect on both species involved? Choices: - disadvantageous - harmful - destructive - beneficial A:
beneficial
------
Answer the following question given this paragraph: To determine the overall voltage of a particular voltaic cell, simply combine the voltages of the oxidation and reduction half reactions. Even if you need to take a multiple of a half reaction for the electrons to cancel, do not take the multiple of the E1/2. Use the values directly as is from - ball-ch14_s03_t01. Spontaneous redox reactions have positive overall voltages. If the voltage of the reaction as written is negative, it is not spontaneous in that direction. Rather, the reverse reaction is the spontaneous redox reaction. Q: Combining the voltages of the oxidation and reduction half reactions helps to determine what? Choices: - slimy - moisture - magnetic - voltage A:
voltage
