Question

Mercury(II) Oxide decomposes upon heating, producing elemental
mercury.

This reaction has an enthalpy value of 90.8 kJ/mol.

How much heat is required to produce 2000 lbs of mercury?
2000 lbs Hg x (453.6 g/lb) = ? grams Hg = approx 9.07E5

2HgO ==> 2Hg + O2 + 90.8 kJ/mol

90.8 kJ/mol x (9.07E5/2*molar mass HgO) = ?
