Question: 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:
Answer: voltage

Question: Answer the following question given this paragraph: Most of Earth's water is salt water in the oceans. As seen below, only 3 percent of Earth's water is fresh ( Figure below ). Freshwater is water that contains little or no dissolved salt. Most freshwater is frozen in ice caps and glaciers. Glaciers cover the peaks of some tall mountains. For example, the Cascades Mountains in North America and the Alps Mountains in Europe are capped with ice. Ice caps cover vast areas of Antarctica and Greenland. Chunks of ice frequently break off ice caps. They form icebergs that float in the oceans. Q: In what type of body of water is most of the earth's water located? Choices: - streams - rivers - seas - oceans A:
Answer: oceans

Question: Answer the following question given this paragraph: Some molecules are not able to satisfy the octet rule by making only single covalent bonds between the atoms. Consider the compound ethene, which has a molecular formula of C 2 H 4 . The carbon atoms are bonded together, with each carbon also being bonded to two hydrogen atoms. Q: The carbon atoms are bonded together, with each carbon also being bonded to two of what kind of atoms? Choices: - calcium - helium - ions - hydrogen A:
Answer:
hydrogen
