According to this balanced chemical equation,

what volume of C2H2 is required to form 40.0L

of CO2?


2C2H2(g) + 502(g) → 2H2O(g) + 4CO2(g)


A. 20.0L

B. 44.8L

C. 80.0L

D. 100 L

Sagot :

Answer: A. 20.0L

Explanation:

According to avogadro's law, equal moles of all gases occupy equal volumes at STP.

The given balanced equation is:

[tex]2C_2H_2(g)+5O_2(g)\rightarrow 2H_2O(g)+4CO_2(g)[/tex]

According to stoichiometry :

4 L of [tex]CO_2[/tex] is formed by = 2 L of [tex]C_2H_2[/tex]

Thus 40.0 L  of [tex]CO_2[/tex] is formed by = [tex]\frac{2 L}{4L}\times 40.0L=20.0L[/tex] of [tex]C_2H_2[/tex]

Thus 20.0 L of [tex]C_2H_2[/tex] is required to form 40.0L  of [tex]CO_2[/tex]
