2 C_2 H_2(g) + 5 O_2(g) \rightarrow 4 CO_2(g) + 2 H_2O(g)
\][/tex]
How many liters of \(C_2 H_2\) are required to produce \(8 \, \text{L}\) of \(CO_2\), assuming the reaction is at STP?
The ratios are: [tex]\(\frac{2 \, \text{L} \, C_2 H_2}{4 \, \text{L} \, CO_2}\)[/tex] or [tex]\(\frac{4 \, \text{L} \, CO_2}{2 \, \text{L} \, C_2 H_2}\)[/tex].
