Could you tell me how to read this chemical equation?
CH4 (g) + 2 O2(g) == CO2(g) + 2 H2O(l) delta H = 890 kJ/mol

It's a thermochemical equation. And thank you in advance for telling me how to read it.

Also, I wonder what (aq) stands for when appearing in an equation.

Answer

Numbers after a certain element are supposed to be small because italki doesn't allow small numbers,  it is read as Methane (CH4) + 2 Oxygen (O2) == Carbon Dioxide (CO2) + 2 Water (H2O). Delta H is the enthalpy, the change in energy, the reaction causes a causes a change in energy of 890 Kilojoules per mol. (aq) means that the reactant was part of a solution.
