Gay Lussac’s Law of Combining Volumes

The reaction given below takes place only in the gaseous state.

$4{\mathrm{N}}_2\mathrm{O}+{\mathrm{CH}}_4 \stackrel{}{\to } {\mathrm{CO}}_2+2{\mathrm{H}}_2\mathrm{O}+4{\mathrm{N}}_2$

If all the volumes are measured at the same temperature and pressure, calculate the volume of dinitrogen oxide required to give $150 {\mathrm{cm}}^3$ of steam.

The volume of gases A, B, C, and D are the ratios 1:2:2:4 under the same conditions of temperature and pressure.

If this ratio of gas volumes refers to the reactants and products of a reaction, which gas law is being observed?
