ok so im not very clear with using E=mct so Id appreciate if someone confirmed/corrected this:
so when we burn something (like propane etc), we use the 'mass' of thw WATER bec it is the water thats being heated?
and in a neutralisation reaction, the mass is sum of the volumes of acid and alkali. And if we need to find the MOLAR enthalpy, we divide by the moles of WATER formed?
