Given the equation 2mg(s) + o2(g) → 2mgo(s) + 72.3 kj, how much heat is involved in the production of 5.0 mol of mgo? question 2

Rudik [331]

The heat is involved in the production of 5.0 mol of MgO is 180 Kj

   calculation

2 Mg (s) +O2 → 2 MgO

From the equation above two moles of MgO is used therefore

72.3 is for 2 moles

that is 72.3 kj = 2moles
? = 5 moles

by cross multiplication

= 72.3 kj × 5/2 = 180 Kj
