Q: What type of winds blow over a limited area? Read this paragraph and choose the correct option from the provided answers: Local winds are winds that blow over a limited area. They are influenced by local geography, such as nearness to an ocean. They include land and sea breezes as well as monsoons. Choices: - hurricanes - gales - trade winds - local winds A:
local winds

Q: When an oxidation number of an atom is decreased in the course of a redox reaction, that atom is being what? Read this paragraph and choose the correct option from the provided answers: All redox reactions occur with a simultaneous change in the oxidation numbers of some atoms. At least two elements must change their oxidation numbers. When an oxidation number of an atom is increased in the course of a redox reaction, that atom is being oxidized. When an oxidation number of an atom is decreased in the course of a redox reaction, that atom is being reduced. Thus oxidation and reduction can also be defined in terms of increasing or decreasing oxidation numbers, respectively. Saylor URL: http://www. saylor. org/books. Choices: - replaced - increased - destroyed - reduced A:
(Answer)
reduced

Q: The motion of molecules in a gas is random in magnitude and direction for individual molecules, but a gas of many molecules has a predictable distribution of what, which is called the maxwell-boltzmann distribution? Read this paragraph and choose the correct option from the provided answers: Distribution of Molecular Speeds The motion of molecules in a gas is random in magnitude and direction for individual molecules, but a gas of many molecules has a predictable distribution of molecular speeds. This distribution is called the Maxwell-Boltzmann distribution, after its originators, who calculated it based on kinetic theory, and has since been confirmed experimentally. (See Figure 13.23. ) The distribution has a long tail, because a few molecules may go several times the rms speed. The most probable speed v p is less than the rms speed. Choices: - molecular size - molecular rate - molecular shape - molecular speeds A:
(A).
molecular speeds

Ques:Q: What combines with rain to form acid rain? Read this paragraph and choose the correct option from the provided answers: Courtesy of the U. S. EPA. Nitrogen and sulfur oxides combine with rain to form acid rain . Public Domain. Choices: - suction and sulfur oxides - compost and sulfur oxides - carbon dioxide and sulfur oxides - nitrogen and sulfur oxides A:

Ans:nitrogen and sulfur oxides

Q: What "kind" of water may take longer to become contaminated than surface water, while the natural cleaning process may take longer? Read this paragraph and choose the correct option from the provided answers: Water pollution happens when contaminants enter water bodies. Contaminants are any substances that harm the health of the environment or humans. Most contaminants enter the water because of humans. Surface water (river or lake) can be exposed to and contaminated by acid rain, storm water runoff, pesticide runoff, and industrial waste. This water is cleaned somewhat by exposure to sunlight, aeration, and microorganisms in the water. Groundwater (private wells and some public water supplies) generally takes longer to become contaminated, but the natural cleaning process also may take much longer. Groundwater can be contaminated by disease-producing pathogens, careless disposal of hazardous household chemical-containing products, agricultural chemicals, and leaking underground storage tanks. Choices: - lake water - spring water - dam water - groundwater A:
groundwater
