🤓 Based on our data, we think this question is relevant for Professor Love's class at East Tennessee State University.
We’re being asked to determine the standard enthalpy change (ΔH˚rxn) for the balanced reaction:
HgO(s) → Hg(l) + O2(g)
Joseph Priestly prepared oxygen in 1774 by heating red mercury(II) oxide with sunlight focused through a lens. How much heat is required to decompose exactly 1 mole of red HgO(s) to Hg(l) and O2(g) under standard conditions?
