Hello
We know that polar molecules' attraction is stronger than that of non polar ones; this can be a good basis for us to check the substances' polarity. Knowing that polar forces are stronger, we can eliminate all options referring to them as being the weaker force; that is, options C and A. Next, we know that stronger forces will result in lower volatility so we can eliminate option D. The answer is B, assuming the compound has an odor.
The number of electrons in the outermost shell of an atom determines<span> its </span>reactivity<span>.</span><span>
</span>
<span>Then amount of energy required to break the attractions among the solute particles and among the solvent particles is </span>less than the energy released as attractions form between solute and solvent particles.
2. vinegar and baking soda mixing and creating bubbles, if it changes form like bubbles or produces heat then it’s chemical changes.
