2Ag(s) + F2(g) ? 2AgF(s); ?H = -409.2 kJ
A) If 2 atoms of silver metal react with 1 molecule of fluorine gas at constant pressure, 2 formula units of solid sodium fluoride are produced and 409.2 kJ of heat is released.
B) If 2 mol of silver metal react with 1 mol of fluorine gas at constant pressure, 2 mol of solid sodium fluoride is produced and 409.2 kJ of heat is consumed.
C) If 2 atoms of silver metal react with 1 molecule of fluorine gas at constant pressure, 2 formula units of solid sodium fluoride are produced and 409.2 kJ of heat is consumed.
D) If 2 mol of silver metal react with 1 mol of fluorine gas at constant pressure, 2 mol of solid sodium fluoride is produced and 409.2 kJ of heat is released.
E) If 2 mol of silver metal react with 1 mol of fluorine gas at constant volume, 2 mol of solid sodium fluoride is produced and 409.2 kJ of heat is consumed.
