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

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
