A particular solvent with δvaps∘=112. 9j k−1 mol−1 δ v a p s ∘ = 112. 9 j k − 1 m o l − 1 and δvaph∘=38. 0kj mol−1 δ v a p h ∘ = 38. 0 k j m o l − 1 is being considered for an experiment. In the experiment, which is to be run at 75 ∘c ∘ c , the solvent must not boil. Based on the entropy change of the universe associated with the vaporization reaction, would this solvent be suitable and why or why not?.

Analyze the analogy and read the information below it. fish : fin : : bird : wing if you were reading this aloud, you would say, "fish is to fin as bird is to wing." this analogy uses parts of an animal to relate to the whole animal. much like how a fin a fish move, so does a wing a bird move. which analogy also uses parts to relate to the whole? sky : blue : : dirt : brown flower : petal : : tree : leaf car : road : : boat : water food : sandwich : : sport : softball

Ateacher attaches a ball to a meter long string and whirls it around in a horizontal circle at constant speed. the teacher explains that the string is what makes the ball go in a circle. why is the string necessary? a) the string is needed to apply a torque to the ball. b) the string is needed to push on the ball to get it up to speed. c) circle motion requires an inertia which is provided by the string. d) circle motion requires a force to give it a centripetal acceleratio

In which text sample are the ideas organized most logically? a. a butterfly starts its life as an egg. the egg hatches to reveal a tiny caterpillar. the caterpillar eats a lot of leaves. it grows quickly, shedding its skin as it grows. this shedding takes place four or more times in a process known as molting. the caterpillar then forms a pupa or chrysalis. inside the chrysalis, the caterpillar slowly transforms into a beautiful butterfly. b. the molting process is characteristic of caterpillars. eventually the caterpillar grows into a beautiful butterfly. the caterpillar eats a lot of leaves, growing quickly. as a result, it becomes too big for its skin, and it has to shed its skin four or more times. the caterpillar hatches from the egg laid by a butterfly. c. a tiny caterpillar hatches from the egg. the egg is the starting point of a butterfly’s life. when it becomes a caterpillar, it eats a lot of leaves. it grows quickly, shedding its skin as it grows. this shedding takes place four or more times. this process is known as molting. the caterpillar then forms a pupa or chrysalis. then the caterpillar slowly transforms into a beautiful butterfly. d. the caterpillar forms a pupa or chrysalis. inside the chrysalis, the caterpillar slowly transforms into a beautiful butterfly. but where does the caterpillar appear from? a caterpillar hatches from an egg. the egg is the starting point of a butterfly’s life. when it becomes a caterpillar, it eats a lot of leaves. it grows quickly, shedding its skin as it grows. this shedding takes place four or more times in a process known as molting.
