We are asked to determine the minimum mass of hydrogen gas required to produce 366 kJ of heat.
We'll use the thermochemical equation to calculate the mass of H2.
Molar mass H2 = 2.02 g/mol
2 H2(g) + O2(g) → 2 H2O(g) ΔH = –483.5 kJ/mol
Hydrogen gas reacts with oxygen to form water.
2 H2(g) + O2(g) → 2 H2O(g) ΔH = –483.5 kJ/mol
Determine the minimum mass of hydrogen gas required to produce 366 kJ of heat.
