A1.00 g sample of n-hexane (c6h14) undergoes complete combustion with excess o2 in a bomb calorimeter. the temperature of the 1502 g of water surrounding the bomb rises from 22.64°c to 29.30°c. the heat capacity of the hardware component of the calorimeter (everything that is not water) is 4042 j/°c. what is δu for the combustion of n-c6h14? one mole of n-c6h14 is 86.1 g. the specific heat of water is 4.184 j/g·°c.

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
