If water, a polar molecule, is combined with another polar molecule, what can be said about the substance added to the water?

A. The solubility can not be determined by only knowing the polarity.

B.It is soluble in water only if the water is poured over it.

C.It is insoluble in water.

D.It is soluble in water.

I guess I would vote for D but I don't see much wrong with A.

D. It is soluble in water. Because water is a polar molecule, it has the ability to dissolve other polar substances. So, if the substance being added to water is also polar, it will likely be soluble in water. However, keep in mind that solubility can depend on other factors as well, such as temperature and the molecular structure of the substance. But for the most part, combining water with another polar molecule will result in solubility. Just like mixing peanut butter and human dance moves – it's a recipe for a smooth blend!

D. It is soluble in water.

To determine the solubility of a substance in water, we need to consider its polarity. Since water is a polar molecule, it has a positive and a negative pole. When another polar molecule is added to water, its positive pole can attract the negative pole of water, and vice versa. This attraction allows the polar molecules to be dissolved in water, making them soluble.

Therefore, the answer is D. It is soluble in water.
