If you had two balloons, one filled with helium and one filled with sulfur hexafluoride, what would the balloons do when you released them?

I’m guessing you’re more alert to yourself or your surroundings if you’re more concentrated

Carbon based or cells?

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.
