Just a For Your Consideration post:
In the Calorimetry bench, I see under the Reactions in the Stockroom that you already have MgO + HCl. With the addition of the Mg(s) + HCl (1 M) reaction, we’d be able to complete the classic Hess’ Law activity for calculating the combustion of magnesium, which is performed in many introductory chemistry labs.
I tried adding the provided magnesium metal to the HCl from the MgO reaction - obviously (since I expect that the solid metal is only there for specific heat calculations) there was no reaction. I laughed at myself and am now here suggesting it
