Problem Page Question A major component of gasoline is octane C8H18. When liquid octane is burned in air it reacts with oxygen O

KATRIN_1 [288]

Answer:

0.3mol C8H18

Explanation:

For this we must first look at the reaction taking place:

C8H18+O2 --> H2O + CO2

Balancing the equation we get:

2(C8H18)+25(O2) --> 18(H2O) + 16(CO2)

Form there we now need to know how many moles of Octane are needed to produce 2.4moles of H2O. The conversion is as follows:

2.4molH2O ((2mol of C8H18)/(18mol of H2O)) = 0.3mol C8H18

Keisha finds instructions for a demonstration on gas laws.

Dmitrij [34]

The purpose of this experiment is to demonstrate the relationship between pressure and volume. Pulling the plunger back increases the volume of the gas in the syringe thereby increasing the size of the marshmallow but pressure is reduced. The relationship to be demonstrated is that pressure and volume have an inverse relationship.
