30. 2H2(g) + O2 ------> 2H2O(g) and ΔHrxn = -483.5 kJ b) If 50.0g of water is produced, how much energy was released?
Added by Beth M.
Step 1
First, we need to find the moles of water produced. To do this, we'll use the molar mass of water, which is 18.02 g/mol. moles of water = (50.0 g) / (18.02 g/mol) = 2.775 moles Show more…

ΔH = +285.8 kJ/mol of H2O for the decomposition of water by the reaction 2 H2O() → 2 H2(g) + O2(g). How many grams of water can be decomposed by 5.00 × 103 kJ of energy?

ΔH = +572 kJ for the decomposition of water by the reaction 2 H2O(l) → 2 H2(g) + O2(g). How many grams of water can be decomposed by 5,932 kJ of energy? (Hint: the standard unit for heat from a reaction is kJ/mol and the molar mass of water is 18.01 g/mol) (3 SF)

The reaction of hydrogen and oxygen gases produces $15.0 \mathrm{~g}$ of water and releases 48.0 kcal of heat. How much energy is required to decompose $15.0 \mathrm{~g}$ of water into hydrogen and oxygen gases?
