hlorine is used by textile manufacturers to bleach cloth. Excess chlorine is destroyed by its reaction with sodium thiosulfate, Na2S2O3, as follows: Na2S2O3(aq) + 4Cl2(g) + 5H2O 2NaHSO4(aq) + 8HCl(aq) Using the concepts established in the previous parts, answer the following questions about the following reaction: The octane in gasoline burns according to the following equation: 2C8H18 + 25O2 → 16CO2 + 18H2O (a) How many moles of O2 are needed to react fully with 6.84 mol of octane? (b) How many moles of CO2 can form from 0.511 mol of octane? (c) How many moles of water are produced by the combustion of 8.20 mol of octane? (d) If this reaction is used to synthesize 6.00 mol of CO2, how many moles of oxygen are needed? How many moles of octane are needed? ? mol O2 ? mol C8H18 Thanks.

The octane in gasoline burns according to the following equation:
2C8H18 + 25O2 → 16CO2 + 18H2O
(a) How many moles of O2 are needed to react fully with 6.84 mol of octane?
(b) How many moles of CO2 can form from 0.511 mol of octane?
(c) How many moles of water are produced by the combustion of 8.20 mol of octane?
(d) If this reaction is used to synthesize 6.00 mol of CO2, how many moles of oxygen are needed? How many moles of octane are needed?
? mol O2
? mol C8H18
