E. true-false classify each of these statements as always true, at; sometimes true, st; or never true, nt. 26. two small bicycle pumps are filled with different gases; one contains he, the other ar. using the same pressure, it will take longer to force out the he than the ar. nt 27. theoretically, an ideal gas will contract in volume with increasing pressure and reduced temperature until absolute zero is reached. at 28. to obtain a value for the number of moles using the ideal gas law, one uses the conditions of stp. 29. the kinetic energy of a moving body is directly proportional to the square of its velocity. st

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
