Pls Answer this
A nuclide of Superscript 64 subscript 29 upper C u. absorbs a positron. Which is the resulting atom?
Superscript 65 subscript 29 upper C u.
Superscript 63 subscript 29 upper C u.
Superscript 64 subscript 28 upper N i.
Superscript 64 subscript 30 upper Z n.

A.(nh4)(2co3)is the correct answer 

The answer would be true

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.
