what is the molar ratio between oxygen and carbon dioxide, given the following equation? 2C4H10 + 13O2 right arrow 8CO2 + 10H2O

Respuesta :

2C4H10 + 13O2 -----------> 8CO2 + 10H2O

Number of moles 13 mole of O2 : 8 mole of CO2

Molar ratio: n(O2) :n(CO2) = 13 : 8

n is a number of moles.

Answer : The molar ratio between the oxygen and carbon dioxide is, 13 : 8

Explanation :

The given balanced chemical reaction is :

[tex]2C_4H_{10}+13O_2\rightarrow 8CO_2+10H_2O[/tex]

By the stoichiometry we conclude that, 2 moles of [tex]C_4H_{10}[/tex] react with 13 moles of [tex]O_2[/tex] to give 8 moles of [tex]CO_2[/tex] and 10 moles of [tex]H_2O[/tex] as a product.

That means,

The molar ratio between the [tex]C_4H_{10}:O_2:CO_2:H_2O[/tex] are [tex]2:13:8:10[/tex] respectively.

Thus, the molar ratio between the [tex]O_2:CO_2[/tex] is, [tex]13:8[/tex] respectively.
