The graph shows the half-life of Uranium-235. What is the half-life of this isotope?

Iam not going to tell you

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.

The disturbance is only parallel to the motion of the wave.

They adding another layer their bahaviors.
