A major component of gasoline is octane (C8H18). When liquid octane is burned in the air it reacts with oxygen gas to produce carbon dioxide gas and water vapor.
Calculate the moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

0.027 moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen.

Explanation:

Moles of oxygen gas = 0.085 mol

According to reaction, 50 moles of oxygen gives 16 moles of carbon dioxide gas, then 0.085 moles of oxygen gas will give:

of carbon dioxide

0.027 moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
