Please help me answer these four parts asap! Consider the following balanced thermochemical equation: 2 H2(g) + O2(g) -> 2 H2O(l) ΔH = -572 kJ Based on this, answer the following. Show your work/explain your reasoning. a. Is this reaction endothermic or exothermic? Explain your reasoning. (BT2: Understand) b. How much heat (in kJ) is released when 5 moles of H2O are produced? (BT3: Apply) c. How much heat (in kJ) is released when 5 grams of H2O are produced? d. What mass of hydrogen would need to react to produce 5.0 x 10^4 kJ of heat? (BT3: Apply)
