1. Calculate the molar mass of Cl2:
Molar mass of Cl2 = 2(Cl) = 2(35.45 g/mol) = 70.90 g/mol
2. Calculate the number of moles of Cl2:
Number of moles = Mass / Molar mass = 106 g / 70.90 g/mol = 1.49 mol
Since the balanced equation shows that 2 moles of Cl2 produce 687 kJ of heat, we can use this information to find the heat produced when 1.49 mol of Cl2 reacts:
687 kJ / 2 mol = 343.5 kJ/mol
Finally, we can calculate the total heat produced when 1.49 mol of Cl2 reacts:
1.49 mol × 343.5 kJ/mol = 511.715 kJ
Rounded to the nearest whole number, the heat produced when 106 g of Cl2 reacts is approximately 513 kJ.
