Question

1. To get iron out of iron ore (the stuff that actually comes out of the ground), you need to heat it with charcoal (C). The reaction is: 2(Fe2O3) + C .......... 4 Fe + 3 (CO2) How many kilograms of iron would you produce by processing 15.00 kg of iron ore?

2. Burning octene is: C8H16 + 12 (O2) ......... 8 (CO2) + 8 (H2O) How many grams of O2 would you require to burn 2.00 moles of octene?

3. Burning octane is: 2 (C8H18) + 25 (O2) ......... 16 (CO2) + 18 (H2O) How many moles of CO2 would you produce by burning 566 grams of octane?

4. To get iron out of iron ore (the stuff that actually comes out of the ground), you need to heat it with charcoal (C). The reaction is: 2(Fe2O3) + 3C .......... 4 Fe + 3 (CO2) How many moles of iron would you produce by processing 2.37 moles of iron ore?

5.Burning octane is: 2 (C8H18) + 25 (O2) ......... 16 (CO2) + 18 (H2O) How many moles of CO2 would you produce by burning 2.37 moles of octane?
