Chemistry: Post your doubts here!
Number of gas moles on the left hand side is 1. Number of gas moles on the right hand side is 2. Increasing the pressure favors backward reaction (so yield of propan-2-ol increases, yield of propanone and hydrogen decreases) -
Chemistry: Post your doubts here!
Oh you have no idea just how much AS chemistry, physics and biology overlap. Quite a few times I've gained marks in one subject because of one of the other two. You should also know that carbonic acid is not an acid that frequently comes in contact with your teeth (unless you live on coke, that... -

I still don't get why you're even mentioning carbonic acid. :/ If you've studied bio, you'd know it's usually lactic acid that that forms in the teeth. I feel I'm missing something? -

Carbonic acid? :confused: Where's the carbon in the question? I don't have a solid, convincing answer for this either. The best I can come up with is that even if calcium ions react with the acids, they still remain in the solution as calcium ions (unlike the other two reactions above) and thus... -

Can ethene be polymerized in a single reaction or no? I remember seeing a question that tests the knowledge of this twice (maybe more) and now I can't remember the answer. -

Wait... so lemme take everything from the top so there's no confusion. Reaction 1: This does not seem to have an acid/base in it. However, we do know from our knowledge about the use of SO2 as a preservative that it acts as a reducing agent (so B is eliminated) and also makes food acidic... -

Ugh sorry, again. :p I haven't had my daily cup of tea. There's too much on my mind at the moment (exams?). I meant protons. -
Chemistry: Post your doubts here!
Sorry, I was explaining it right but I miswrote the ions. They show the products as ions, but what is really forming is H2SO3. HSO3- is accepting protons to form H2SO3. SO3 (2-) is the ion acting like an acid. -

Page 185 of the latest coursebook mentions the formation of complex ions when ammonia is added to silver halides. -

Dude don't mislead people. We ARE supposed to know what ligands are [complex ion formation]. I've seen this term used in the book. -

For the first part they ARE supposed to use 5C0 , but since 5C0 = 1, they are not showing it (like how (1/3)^0 is also = 1, which they're supposed to show but don't because they're just lazy lol). They're using it because they're applying binomial theorem (distribution) in all the parts. n... -

Why 5P4? There are 4 vowels (with one repetition) and 5 consonants (with 1 repetition) and you are to use all of them in your arrangements. -

What? That's not a carbonyl compound. Though if you're asking what carbonyl compound the given compound originally was before hydrolysis, then it was (CH3)2CO (i.e propanone) -

Ooops, sorry. I misread the question. NDH3Cl would produce NH3 or NH2D at best. It can_not produce ND3. -

Q11) Notice the words in the question '[...]reaction between powdered aluminium and powdered barium nitrate in which heat is evolved[...]'. The formation of Al2O3 is a highly exothermic reaction. Q13) I'm pretty sure that they're testing our knowledge of solubility. We know all nitrates are...
