Answer the following question given this paragraph: [PCl 3][Cl 2] (0.135)(0.135) = = 0.021 0.87 [PCl 5] The equilibrium constant calculated from the equilibrium concentrations is equal to the value of Kc given in the problem (when rounded to the proper number of significant figures). Thus, the calculated equilibrium concentrations check. Kc =. Q: Because of their reactivity, we do not find most representative metals as free elements where? Choices: - in water - in the atomospher - underground - in nature A:
in nature
(Question)
Answer the following question given this paragraph: Many sponges live on coral reefs, like the one in Figure below . Reef sponges typically have symbiotic relationships with other reef species. For example, the sponges provide shelter for algae, shrimp, and crabs. In return, they get nutrients from the metabolism of the organisms they shelter. Q: Reef sponges typically have what type of beneficial relationships with other reef species? Choices: - parasitic - microbes - mutual - symbiotic A:
(Answer)
symbiotic
Ques: Answer the following question given this paragraph: 34.4 Digestive System Regulation The brain and the endocrine system control digestive processes. The brain controls the responses of hunger and satiety. The endocrine system controls the release of hormones and enzymes required for digestion of food in the digestive tract. Q: What part of the body controls the responses of hunger and satiety? Choices: - heart - small intestine - blood - brain A:
Ans: brain
(Q).
Answer the following question given this paragraph: The age-sex structure of a population is the number of individuals of each sex and age in the population. Age-sex structure influences population growth. It is represented by a population pyramid. The number of survivors at each age is plotted on a survivorship curve. Q: What helps represent age-sex structure of the population? Choices: - habitat chart - density graph - biome model - population pyramid A:
(A).
population pyramid
Ques:Answer the following question given this paragraph: Figure 2.13 Oil and water do not mix. As this macro image of oil and water shows, oil does not dissolve in water but forms droplets instead. This is due to it being a nonpolar compound. (credit: Gautam Dogra). Q: What does oil do when mixed with water? Choices: - dissolves - precipitates - dissappears - forms droplets A:

Ans:forms droplets
Ques:Answer the following question given this paragraph: 34.3 Digestive System Processes Digestion begins with ingestion, where the food is taken in the mouth. Digestion and absorption take place in a series of steps with special enzymes playing important roles in digesting carbohydrates, proteins, and lipids. Elimination describes removal of undigested food contents and waste products from the body. While most absorption occurs in the small intestines, the large intestine is responsible for the final removal of water that remains after the absorptive process of the small intestines. The cells that line the large intestine absorb some vitamins as well as any leftover salts and water. The large intestine (colon) is also where feces is formed. Q: Where are feces formed? Choices: - duodenum - liver - small intestine - large intestine A:

Ans:
large intestine
