Don't overreact! A simple experiment demonstrates chemical reactions as scholars mix chemical solutions and metals in a large well plate. They note all changes to the metals, solutions, precipitate, colors, and more. A full data table...

In this lab experiment students are asked to determine the standard molar enthalpy of formation of magnesium oxide, MgO. Students are asked to use Hess's Law and the enthalpy changes of several other solution reactions during this...
