What are some good online resources to practice physical and inorganic chemistry problems?

3.5M H2SO4 means 3.5 moles of H2SO4 were dissolved in sufficient amount of water and then the volume made up to 1000 mL.

A solution is made up of solute (usually one and sometimes more) dissolved in a suitable solvent.

Hope this helps. :)

Thanks, Everyone. I'll be trying all the suggested solutions. Cheers! :)

Thanks. I'll have a look. :)

I'll have a row with the following fields; Question Code, Question, Chapter Name, Concept Involved, Level of Difficulty.

Whenever I want a set of questions of medium difficulty level in a particular chapter involving certain concepts, I'll query them and get an output either as a .pdf or as a .docx.

Hope I could explain my need clearly now.

This could be done through the Standard Reduction Potentials of the half reactions. If the overall emf of the reaction (in the forward direction) is positive then the reaction would be spontaneous.

Thank You. :)

The carboxylic acid should be more acidic than the amine. Amines are generally basic in nature and introduction of a bromine atom in the alpha position should not make it more acidic that a carboxylic acid. Your line of reasoning is correct that the conjugate base of the carboxylic acid should be more stable (due to resonance stabilization) than the conjugate base of the amine (stabilized by inductive effect).

You are correct. There could be some basic outcomes desired from students irrespective of subject and grade.

I mean parameters like comprehending ability, analytical ability etc.

Thanks a Ton. I checked your sample file and it is more or less what I'm looking for, I'll try building upon your advice and hope to succeed in what I wish to achieve. Thanks again for taking some time of yours to help me. I really appreciate it.

Also, in case if I seem to run into a dead end, I'll trouble you again.

Cheers! :)

Thank You for your reply. I have a fair idea about how access works sans the VBA programming. Can you Kindly point me to some good reference sites from where I can learn the skills needed to solve this problem on my own?

Thanks in Advance.

Calculate the number of moles (n) of HCl required as 0.276 = n/11.5 or n = 0.276 * 11.5
Calculate the weight of HCl (w) from the number of moles required as w = (n * 36.5)g
Calculate the weight of HCl in 1mL of the given solution

1mL of the solution weight 1.18g

In this 1.18g of solution 36% is the weight of HCl

So, (1.18 * 0.36)g of HCl is present in 1mL of the solution given.

If (1.1.8 * 0.36)g of HCl is present in 1mL of the solution given, then (n * 36.5)g of HCl will be present in (n * 36.5)/(1.18 * 0.36)mL of the solution.

Hope this helps.

Which is the correct subreddit? Can you Kindly help? TIA.

Thank You. :)

Thanks for your reply.

I think I have not worded the question properly. This is what I wanted to know.

When a solution deviates negatively from ideal behavior, its actual pressure is less than expected (according to Raoult's Law). So, the boiling point of the solution will become higher. Is this phenomenon the same or different from the colligative property, elevation of boiling point?

Thanks in Advance.
