10. You have oxygen gas in a balloon. At room temperature, 25C, the balloon has a volume of 12 L. You put the balloon in the freezer which is at 0C. Calculate the final volume of the balloon. You can assume that at all times, the balloon is at atmospheric pressure.

Nonmetals usually react by gaining electrons

What is the gold assay

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.
