Answer:
The answer is given below:
Explanation:
First, a knowledge of the chemistry of water and why some substance dissolves well in it, and while some don't even dissolve at all or are partially dissolved in water is needed.
Water in a simple chemistry term consists of two hydrogen atoms and one oxygen atom and is held together by a simple hydrogen bond which is only strong when the molecules are closer. Because oxygen and the hydrogen atoms share electrons, they form two covalent bonds. The covalent bonds of water are polar because of the electronegativity and for a substance to dissolve in water it has to be a polar substance too.
So the conclusions that could be drawn on the substance are: The substance is nonpolar making a separate layer on the water's surface. Stirring or heating the substance has little effect on the solubility in water because as the temperature gets high, solubility even decreases. Most of these substances don't have positive or negative charges.
