Question
The value of ΔH° for the reaction below is -1107 kJ:
2Ba (s) + O2(g) → 2BaO (s)
How many kJ of heat are released when 5.75 g of Ba (s) reacts completely with oxygen to form BaO (s)?
2Ba (s) + O2(g) → 2BaO (s)
How many kJ of heat are released when 5.75 g of Ba (s) reacts completely with oxygen to form BaO (s)?

1107 kJ/2 mol Ba = (1107/2) kJ/mol
(1107/2) kJ/mol x 5.75g/atomic mass Ba = ?
(1107/2) kJ/mol x 5.75g/atomic mass Ba = ?
