Hint: Refer to the Pigment Handbook on page 112 of your lab manual for additional assistance on this question. Group of answer choices The painting is a forgery based on the composition of the blue (Cobalt Blue) pigment. The painting is a forgery based on the composition of BOTH the white (Lead White) and blue (Cobalt Blue) pigments. The painting could be authentic based on the composition of the white (Lead White) and blue (Cobalt Blue) pigments. The painting is a forgery based on the composition of the white (Lead White) pigment.

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
