The following two reactions are important in the blast furnace production of iron metal from iron ore (Fe2O3):2C(s) + O2(g) -> 2CO(g)Fe2O3 + 3CO(g) -> 2Fe + 3CO2Using these balanced reactions, how many moles of O2 are required for the production of 5.00 kg of Fe?A) 67.1 molesB) 29.8 molesC) 7.46 molesD) 89.5 molesE) 16.8 moles

A) 67.1 moles

Explanation:

The balanced reaction is :

To calculate the moles, we use the equation:

According to stoichiometry;

2 moles of iron is produced by 3 moles of carbon monoxide

89.3 moles of iron is produced by= moles of carbon monoxide

2 moles of carbon monoxide is produced by = 1 mole of oxygen

Thus 134 moles of carbon monoxide is produced by = moles of oxygen

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
