53:09 why don't you calculate the enthalpy of combustion for oxygen on the left side of the reaction, only carbon and hydrogen?
@chemistrytutor16 күн бұрын
@piqueblinders7303 Good question. Combustion is an oxidation reaction, so the element reacts fully with oxygen. The element oxygen will not react with itself, as oxygen doesn't burn (although, of course, it supports burning), so it doesn't have an enthalpy of combustion.

42:48 sir why didnt we take x as the starting point and why we took z instead of x
@chemistrytutor2 ай бұрын
Your starting point is set by what it is you need to calculate. Z --> X was our unknown that we needed to calculate so what means we had to start at Z

@chemistrytutor10 ай бұрын
You could in theory be asked about the enthalpy change for any reaction (which all enthalpy change for reaction means) Equally, you do need to know the Equations for neutralisation reactions. I dont think you'll be asked to *define* enthalpy of neutralisation, but you could be expected to work something out

I have some confusion about why u don't include the enthalpy change of combustion of the oxygens at 52:00
@chemistrytutor4 жыл бұрын
Combustion is the reaction between a substance and oxygen. So the oxygen is necessary because it supports the burning process. It doesn't actually burn itself. And if it did burn and we follow the logic... oxygen would be reacting with itself and turning into its own oxide of oxygen, which would be oxygen... so that's what you started with. And that's not a change. So we have it in the reactants to balance the equation, and because its needed to help other things burn, not because it burns.

is a month of doing past papers non stop good enough to land me an A or B at least?
@chemistrytutor10 ай бұрын
Good question. It really depends on where you're starting from. If you're already confident with the core content and will be able to do all past papers at least once in that time... probably, yes. If you're shaky on some or lots of the content, it will take longer. You might find some gaps in your knowledge that take lots of time to fill, and you need to build in time for that. My advice is to start earlier than that. Then you can feel confident you'll have time to deal with the issues that arise

at 51:43 you added 3/2 o2 on both sides. Why did you need the fraction when the equation was already balanced? couldn't it just be o2
@chemistrytutor3 жыл бұрын
There are 4 oxygen atoms in CO2 and 2H2O at the bottom and only 1 in methanol do that's why we needed another 3 oxygen - hence the 3/2 O2. With respect to the reactants at the top, you're right really- 3/2 O2 and 1/2 O2 is really 2 O2

@@chemistrytutor so could the equation just be C + 2H2 + 1/2O2 -> CH3OH + O2 instead of the fractions you used sir? at 51:43

@amirah175 for the equation you've written there are 3 oxygen on the right but only one on the left. You'd need an additional O2 on the left, which is why I combined them into 3/2 O2
