Question

How much heat will be liberated if 8.00g of hydrogen burns in excess oxygen according to the following equation: 2H(g) + O2(g) → 2H2O(l) ∆H = -571.7g .

Answer 1

Answer:

2H 2(g) + O 2(g) → 2H 2O(ℓ) ΔH = −570 kJ. This new quantity ... how much heat is given off when 1.00 g of H 2 reacts? Answer. −15.1 kJ.
