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 ...

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 ...

Each of the two units focuses on a different green chemistry principle. The first examining stoichiometry explores the impacts of low yields such as carbon monoxide from incomplete combustion. By ...
