    the ideal gas equation: pV=nRT. now if you rearrange the equation, you'll get pv/RT=n. So n will always have a constant value for a fixed mass of gas. Hence the expected graph for pV/RT against p should be a horizontal line. EXTRA: If you want to plot a graph having the same axes but with a...

    In flooded soils, like those used for rice cultivation, the oxygen content is low. In such soils, anaerobic bacteria cause the loss of nitrogen from the soil as shown in the following sequence. In which step is the change in oxidation number (oxidation state) of nitrogen different to the changes...
