1- what will happen to the glucose solution in the A column (increase - decrease - nothing)
2- what will happen to the Copper sulfide in the B column (increase - decrease - nothing)

I suggest the answers will be:
1- nothing
2- increase


what are the correct answers ?


thanks

That really will depend on what is actually being done.  You haven't provided up with the reaction setup, or anything useful at all.

I think the assumption is that no reaction is happening, only osmosis.

However...

what are the correct answers ?

It doesn't work that way here - you tell us what you think the answer is and provide your reasoning, and we try to help you find the answer.

no no no I'm not talking about any reaction
just a notmal osmosis < and what happens to the the percentages of the salt and glucose after osmosis

Great, now that we have the image, we know something important for the question.  Now, what can you guess is likely to happen in each case?  For example, if there weren't a membrane, but a solid wall, you wouldn't expect any change.  If there were no membrane, just open space, you'd expect the solutions to mix. Given the membrane you have, what can, and what can't change?

Are any of the Copper Sulfides substantially water soluble? Getting a 2.5% solution might be a tad hard.

copper sulfide will go to the right side < and water will go also to the right side !!!
so glucose solution will still 60% in the right side?
and copper sulfide will be less than 2.5% in the left side ?

[fledarmus]

If both water and copper sulfide are going to the right side, what does that do to the concentration of the glucose on that side?

concentration of the glucose will decrease by increasing the column of the water ...
so the answer will be ... "decrease"
right ?

[fledarmus]

That would be my answer
