Question

For the reaction CH4(g) + 2 O2(g) ---> CO2(g) + 2 H2O(l) ΔH° = -890.3 kJ. What is the enthalpy change of the molecules (in kJ) if 8.61 g of O2 reacts completely with CH4? Enter your answer as a sign and a number, ignoring units.

Step 1

61 g. Given: - Mass of O2 = 8.61 g - Molar mass of O2 = 32 g/mol Number of moles = Mass / Molar mass Number of moles = 8.61 g / 32 g/mol Number of moles = 0.269 moles Show more…
