When butane (C4H10) reacts with oxygen, ... carbon dioxide and water are produced. The balanced equation for this reaction is:
2 C4H10 (g) + 13 O2 (g) 8 CO2 (g) + 10 H2O (g)
If 8 moles of butane (C4H10) react,
The reaction consumes ? moles of oxygen
The reaction produces ? moles of carbon dioxide and ? moles of water
