Maria and miquel were enjoying the fireworks when they got into a chemistry argument. maria insisted that the fireworks were the result of a chemical reaction. miguel disagreed. what would you tell them to solve this argument.
a) it is a change of state, solid to gas, due to the addition of energy.
b) it was a physical reaction since the fuse was lit and heat was produced.
c) the color changes and the release of energy indicate a chemical reaction.
d) it is an endothermic reaction because energy was added; therefore it is a chemical reaction

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
