the electronic configuration of sulfur is 2.8.6. explain how you can work out the formula of sulfur
chloride by looking at the numbers of electrons in the two types of atom in a molecule of sulfur chloride.

B. a graduated substance

They are all solids.

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.
