radii depends on number of electron not on number of neutron so this property remains the sameisotopes can have more neutrons. Wouldn't that mean they'd have bigger radii?

I'm not that good in chemistry, but from my understanding it cant be a,b, or d because these three properties are also present in NaCl and MgO and the question says that CsCl has a different structure than these two, so the only distinct property that CsCl has is the radii ratio.Ans is c but why..
Let me know if this helped.I'm not that good in chemistry, but from my understanding it cant be a,b, or d because these three properties are also present in NaCl and MgO and the question says that CsCl has a different structure than these two, so the only distinct property that CsCl has is the radii ratio.
Yea thanks manLet me know if this helped.
First write the balanced equation.
2H2S + 3O2 ------> 2H2o + 2SO2
(Note:For AS you're not required to know this equation by heart but whenever such a question appears, there are either hints in it about the products or the products are stated explicitly. Nonetheless, you're expected to know the oxidation/combustion products of H2 and S2. )
Moles of H2S = Mass/Molar Mass = 8.65/((32.1 + 2) = 173/682
Moles of O2 = (3 x (173/682))/2 (since mole ratio H2S:O2 = 2:3 from the equation) = 519/1364
Volume = moles x 24 = (519/1364) x 24 = 9.13 dm^3
the strongest bond to break will require the highest energy to break, and thus will linger around for the longest. That should help you from the chemistry point of view, though biologists would have learnt to compare their strength also. Ionic bonds in general are stronger than disulphide bonds.View attachment 65374Help please

I guess the covalent S-S bond is indeed stronger than the zwitterionic interactions. I mean in chemistry, when you have to break covalent bond in the sense of a giant molecular lattice network, that takes roughly the same or even larger amount of energy to break, i.e. to melt a giant ionic framework.Bu
but the answer is A , how?
Can you help with this please?Hi all, I have added more short tutorial videos covering specific concepts, like quick-bites with worked examples, explaining step-by-step how to proceed with calculations/explanations. These complement the longer videos that cover full past paper tutorials.

I am Mr Onn, a chemist and a teacher. I graduated from University of Oxford, with a first class honours in Master of Chemistry (MChem), funded by the Brunei ...www.youtube.com
My videos/YouTube channel try to achieve more than just solving a paper or following mark scheme. Some have found some mistakes within, which is good. The viewers are learning! I don't usually try to correlate to mark schemes, and hey mistakes are common, but I try to minimise mine of course.
If you like my teaching style/explanations, please subscribe to the channel. Do drop comments if there are areas you wish me to cover. Learning chemistry is more than just about acing the exams. If you understand the story behind the concepts, then you will get the grades naturally.
Help please!!!radii depends on number of electron not on number of neutron so this property remains the same
Help please!!!
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
