Stoichiometric combustion of 12 kg of carbon requires _____________ of oxygen?
Correct answer: A. All A., B. and C.
- A. All A., B. and C.
- B. 22.4 Nm3
- C. 32 kg
- D. 1kg mole
Explanation
Twelve kilograms of carbon is 1 kg-mole, and complete combustion requires 1 kg-mole of oxygen. This is equal to 32 kg or approximately 22.4 Nm³ of oxygen, so all three values represent the same quantity.
