In gasoline vehicles like the Ford Bronco, octane combines with oxygen gas to create an explosion. This explosion is what powers

the vehicle. A product of this reaction is carbon dioxide which has been attributed to global warming. How many grams of carbon dioxide are produced for every 350 grams of octane reacted in the engine? 2C8H18 + 25 O2 -> 16 CO2 + 18 H2O

Answer:  1082 g of carbon dioxide are produced for every 350 grams of octane reacted in the engine

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} C_8H_{18}=\frac{350g}{114g/mol}=3.07moles

2C_8H_{18}+25O_2(g)\rightarrow 16CO_2+18H_2O

According to stoichiometry :

As 2 moles of octane give = 16 moles of CO_2

Thus 3.07 moles of octane will give =\frac{16}{2}\times 3.07=24.6moles  of CO_2

Mass of CO_2=moles\times {\text {Molar mass}}=24.6moles\times 44g/mol=1082g

Thus 1082 g of carbon dioxide are produced for every 350 grams of octane reacted in the engine

Sound waves are transverse mechanical waves. <br><br> True<br> False
allochka39001 [22]

False

Explanation:

Sound waves are longitudinal mechanical waves.

Mechanical waves are waves that requires a medium to propagate them.

  • A transverse wave is a wave that is propagated perpendicularly to its source.
  • An example is electromagnetic radiation.
  • A longitudinal wave is a wave that is directed parallel to their source.
  • Sound wave is a longitudinal wave.
  • It has series of rarefaction and compression along its travel path.
  • Rarefaction are areas of sparse particles.
  • Compression are areas with dense particles.
