90.0 $\mathrm{cm^3}$ of buta-1,3-diene and 150.0 $\mathrm{cm^3}$ of hydrogen are mixed in a container at 450 K and 101 kPa and react to form butane only. Determine the maximum volume of butane that can be formed, measured at the same temperature and pressure.

Determine the total volume of gas present in the container at the end of the reaction described in 5a, under the same conditions of temperature and pressure.

30 $\mathrm{cm^3}$ of butane was completely burned in 250 $\mathrm{cm^3}$ of oxygen according to the following equation. $\ce{2C4H10(g) + 13O2(g) -> 8CO2(g) + 10H2O(l)}$ What volume of oxygen remains unreacted, measured at the original conditions? A. 55…

Equal volumes of the gases $\ce{Q2}$ and $\ce{R2}$ are mixed in a sealed container and react until one of them is used up, forming the gas $\ce{QR2}$. The volume of $\ce{QR2}$ formed, measured under the same conditions, is 50 $\mathrm{cm^3}$.…

When $10.0\ \mathrm{cm^3}$ of a gaseous hydrocarbon, $\ce{C_xH_y}$, is burned completely, $70.0\ \mathrm{cm^3}$ of gaseous products is formed. This volume falls to $30.0\ \mathrm{cm^3}$ when the water vapour condenses. All volumes are measured at the same…
