Magnesium also reacts with carbon dioxide to form magnesium oxide and carbon: \[Mg_{(s)} + CO_2 \rightarrow 2 MgO_{(s)} + C_{(s)} \tag{3}\]. { 4s&%P0CIj Magnesium oxide has also been shown to prevent constipation after surgery, treat opioid-induced constipation, and improve functional constipation in children (21). Research shows that magnesium oxide is effective at treating certain medical conditions. The heat energy produced by such reactions can be measured using a calorimeter, a piece of equipment that can isolate the reaction in an insulated container. In a small 2019 randomized, double-blind, controlled study, 34 women with mild to moderate constipation were treated with either 1.5 grams of magnesium oxide or a placebo daily for 4 weeks (19). The reaction you're using represents the formation of magnesium oxide from its elements in their most stable forms at standard state, #25^@"C"# and #"1 atm"#. The enthalpy of formation is the energy change when one mole of a substance is formed from its constituent elements in their standard state. Magnesium oxide is also used as an antacid or a laxative to relieve occasional constipation. Either way, we get the same combination for Hess' Law and that is: Thanks for contributing an answer to Chemistry Stack Exchange!
