It is outside the atom.

Quote from: Siddharth_Pendyala on December 29, 2024, 12:30:15 PMHi Dr. Sharma. I was redoing quiz 6.2 when I came upon this problem. I see that the temperature of the H2O initially and finally is the same, at 23.88°C. So the total energy absorbed by the water is 0 as the temperature change is also 0. So how come option B with product and reactant energies at the same is incorrect?

Thank you!

If you carefully observe the data there is slight rise in temperature of water after 10 and 20 seconds .This means dissolution is exothermic with very small amount of energy released. This energy finally drops back to initial temperature because of loss of heat to the surroundings.
Since it is a simple dissolution process so there are no multiple steps.Option C is out and B and D is out.

Thanks for letting me know.
Doing correction now.

Thank you! It seems to be fixed now and I can open 6.2 quiz.

It isn't the problem that is troubling me, but I just wanted to let you know that two of the answer choices are the exact same - 33°C. Also, in quiz 6.2, this error pops up every time I try to open the quiz:


There are not enough questions in category 9721 to create the question Random question (113550).

Sorry, I don't think it was clear up in the original post, but this is the full error message:

oooh okay thank you

so the elctron is removed? or it is just outside the atom,

Okay thank you, I was kind of confused ,
