A major component of gasoline is octane (C8H18). When liquid octane is burned in air it reacts with oxygen gas to produce carbon dioxide gas and water vapor.

Calculate the moles of water produced by the reaction of 1.00 mol of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant figures.

The answer to your question is 0.4 moles of Oxygen

Explanation:

Data

Octane (C₈H₈)

Oxygen (O₂)

Carbon dioxide (CO₂)

Water (H₂O)

moles of water = ?

moles of Oxygen = 1

Balanced chemical reaction

                   C₈H₈  +10O₂  ⇒   8CO₂  +  4H₂O

              Reactant     Element     Products

                    8                 C                 8

                    8                 H                 8  

                   20                O               20  

Use proportions to solve this problem

                  10 moles of Oxygen 4 moles of water

                    1 mol of Oxygen     x

                    x = (4 x 1) / 10

                    x = 4 / 10

                    x = 0.4 moles of water

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.
