Methane combusts according to the following thermochemical equation:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) ΔH = -891 kJ
If 25 g of methane combusts, how much energy is released in the reaction?

Ответ:
Since oxygen (O) has an atomic mass of 16 g, oxygen gas (O2) has a molecular mass of 2 x 16 = 32 g. We need to convert the given amount of oxygen gas to moles and this can be done by dividing the given mass by the molecular weight of oxygen gas. Hence, moles of oxygen gas = 48 g / 32 g/mole = 1.5 moles.
