Answer:
No, assuming that the salt/sugar is already dissolved
Explanation:
As long as the particle size is too big, it won't filter through. Therefore, if it is dissolved, it will pass through the filter.
If you were to throw rocks in there or something, and they are non-dissolvable, then yes.
Answer:
false should be the correct response.

Explanation:
find longest carbon chain =5
place the Br and Cl on the carbon chain
follow naming rules I guess
Answer:
Attraction, and repulsion!
Explanation:
Magnets have a north pole ans south pole, so when you put south pole and south pole toghther it creates repulsion, and when you put the north pole and north pole it still creats repulsion, but when a south pole and a north pole are put together it creats attraction, your welcome!
Answer:
Explanation:
In recrystallization it is important that the solute dissolve in the solvent at higher temperature and the solute should be insoluble in the solvent at lower temperature. It is also important that the impurities dissolves in the solvent at normal room temperature. This is the principle of recrystallization.
The likely identity of the impurities is that it has high solubility in the solvent at lower temperature.
It is necessary to heat the potassium oxalate solution because potassium oxalate will only be soluble in the solvent at higher temperature. Increase in temperature increases solubility.
Placing the solution in an ice bath will make the solution to cool. On cooling sodium oxalate will recrystallize in a purer solid because it is insoluble in the solvent at low temperature leaving behind the impurities in the solution.
