I Sodium carbonate (NaCO2) is used in heating packs for professional athletes after any
minor injury. When mixed with water, Naco, produces thermal energy (heat energy) and can
reduce injury inflammation. To create a heating pack, doctors mix 0.8 moles of Naco, with an
excess amount of water. What is the mass of sodium carbonate used in the heating packs? Show
