Their food not only has a variable stoichiometry but its C:nutrient ratio also is much higher than their own. To get enough nitrogen, for example, an herbivore often must deal with an excess of ...

Magnesium metal is dissolved in HCl in 500mL Florence flasks covered with balloons. The moles of each reagent are changed in each flask in order to demonstrate the limiting reagent concept. In flasks ...

The range of compositions allowed for the intermetallic is narrow, its width (in composition) indicating the departure from stoichiometry that can occur while maintaining the same crystal structure.
