Using the root-mean-square speed, vrms, estimate the mean free path of the nitrogen molecules in the classroom as room temperature (300 k). what is the average time between collisions? take the radius of a nitrogen molecule to be 0.1 nm and the density of the air to be 1.2 kg/m3 . a nitrogen molecule contains 28 nucleons (protons and neutrons). vrms = 515 m/s; t = 0.6 ns

Answer the questions about this reaction: nai(aq) + cl2(g) β 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) β nacl(aq) + i2(g) c. +1/na+1e- -> 0 /na d. -1/2i -> 0/i2+2e- e. no f. 4nai(aq) + cl2(g) β 4nacl(aq) + i2(g) g. 2nai(aq) + cl2(g) β 2nacl(aq) + i2(g) h. 4nai(aq) + 2cl2(g) β 4nacl(aq) + 2i2(g) i. nai(aq) + cl2(g) β nacl(aq) + i2(g) j. 0/cl2+2e -> -1/2cl- k. yes
