. A student carries out an experiment. She clears an area of soil in her backyard. She keeps the soil watered and makes careful weekly observations of the area. She uses a notebook to record data about the plant growth in the area of study. Originally she observes only worm and insect activity in the soil. After 2 weeks she notices the growth of grass and weeds in the soil. She also notices an increase in insect activity in the area. She continues her observations over a period of three months. By the end of the experiment, the soil is almost completely covered with grass and weeds. She also notices that some tree seedlings have taken root and are beginning to grow. On the final day of her observations, she notices a rabbit eating the grass. Which of the following would the student be able to analyze by looking at her collected data
A. Animal Reproduction
B. Decomposition
C. Ecological succession
D. Climax Community

Answer the questions about this reaction: nai(aq) + cl2(g) → nacl(aq) + i2(g) write the oxidation and reduction half-reactions: oxidation half-reaction: reduction half-reaction: based on the table of relative strengths of oxidizing and reducing agents (b-18), would these reactants form these products? write the balanced equation: answer options: a. 0/na -> +1/na+1e- b. nai(aq) + cl2(g) → nacl(aq) + i2(g) c. +1/na+1e- -> 0 /na d. -1/2i -> 0/i2+2e- e. no f. 4nai(aq) + cl2(g) → 4nacl(aq) + i2(g) g. 2nai(aq) + cl2(g) → 2nacl(aq) + i2(g) h. 4nai(aq) + 2cl2(g) → 4nacl(aq) + 2i2(g) i. nai(aq) + cl2(g) → nacl(aq) + i2(g) j. 0/cl2+2e -> -1/2cl- k. yes
