when butane, c4h10, undergoes combustion, it reacts with o2 to form co2 and h2o. how many moles of o2 are required to react completely with 10.6 moles of butane?

Respuesta :

189.8 mol of O₂ are required to react completely with 10.6 moles of butane.

What are combustion reaction?

An accident occurred when the Hindenburg, an airship filled with hydrogen, tried to land in New Jersey in 1937. 36 persons were killed when the airship was destroyed and the hydrogen instantly exploded in a massive explosion. The chemical process was straightforward: water was created when hydrogen and oxygen combined.

A hydrocarbon, a substance comprised only of carbon and hydrogen, is involved in numerous combustion reactions. Carbon dioxide and water are the byproducts of the burning of hydrocarbons. Since their combustion produces more amounts of heat energy, many hydrocarbons are use fuel. Gas grills frequently use propane (C3H8) as their fuel source. Propane is a gaseous hydrocarbon.

Reaction is:

C₄H₁₀ + [tex]\frac{13O_{2} }{2}[/tex] → 4CO₂ + 5H₂O

Given,

no. moles of butane = 29.2 mol

from the balanced chemical equation,

we can say that:

1 mol of C₄H₁₀ requires [tex]\frac{13}{2}[/tex] moles of O₂

29.2 mol of C₄H₁₀ requires [tex]\frac{13}{2}[/tex] × 29.2

⇒189.8 mol of O₂
