What do the symbols tell you about the conditions of the reactions shown to the right? check all of the boxes that apply

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
