The octane rating of gasoline is a relationship of the burning efficiency of the given gasoline mixture to the burning efficiency of octane (C8H18). (Figure 1) Like most hydrocarbons, octane reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is
C8H18(g)+O2(g)→CO2(g)+H2O(g)
1-Determine the balanced chemical equation for this reaction.
C8H18(g)+O2(g)→CO2(g)+H2O(g)
0.270 mol of octane is allowed to react with 0.660 mol of oxygen. Which is the limiting reactant?
2- 0.270 of octane is allowed to react with 0.660 of oxygen. Which is the limiting reactant?
| octane | |
| oxygen |
3-How many moles of water are produced in this reaction?
4-After the reaction, how much octane is left?

efficiency of the given gasoline mixture to the burning efficiency
of octane (C8H18). (Figure 1) Like most hydrocarbons, octane reacts
with oxygen gas to produce carbon dioxide and water. The unbalanced
equation for this reaction is C8H18(g)+O2(g)→CO2(g)+H2O(g)

Q2-
octane is a gasoline. Complete combustion of octane yields
component of CO2 combustion produces co and Hzo. In a certain run,
and H Incomplete 2.345 gal of octane is burned in an engine. The
total mass of co, com, and H20 produced is 14.053 kg. Calculate the
efficiency of the process, that is, calculate the fraction of
octane converted to co2. The density of octane is 2.65 kg/gal
The combustion of octane C8H18 (a component in gasoline) in the presence of oxygen proceeds according...
The combustion of octane C8H18 (a
component in gasoline) in the presence of oxygen proceeds according
to the following balanced equation:
2 C8H18 (l) + 25 O2 (g)
----> 16CO2 (g) + 18H2O
(l)
0.0500 L of octane (density 0.702 g/mL) was allowed to burn in
the presence of 155 g
of oxygen gas. The actual yield of water produced in this
reaction was 38.4 grams.
a. Determine the theoretical yield for the water.
b. Determine the percent yield.
