All right, so we have the combustion equation for methane, so ch4 plus two moles of oxygen gas, and you're given co2 and should be two moles of water, right? so, and we're told that delta h is minus 891 kilojoules.

The first question says, what is the quantity of heat released for each mole of water formed, right? so, the enthalpy change for this to, you know, since for it to be balanced, right? the quantity of heat q would be minus 8 .1 divided by two, and so you would have minus 445 .5 kilojoules.

And for b, right, you should have, sorry, it says as written, apologies.
01:12
So, since it says a reading, we don't have to balance it.
01:16
We're not told to balance it as written.
01:19
So, this is just one mole...
