Is there any substance with negative value of cubical expansivity? If so, present an example to strengthen your

It is theoretically possible for a substance to have a negative value of cubical expansivity, which means that the substance would contract rather than expand when the temperature increases. However, it is very rare for a substance to have a negative value of cubical expansivity over a significant range of temperatures.

One example of a substance that has a negative value of cubical expansivity over a limited range of temperatures is water. Water has a positive value of cubical expansivity at...

Following reactions occur at cathode during the electrolysis of aqueous copper (II) chloride solution:

Cu2+(aq) + 2 e-2 ———–> Cu(s) E = + 0.34 V

H+(aq) + e-1 ————-> 1/2H2(g) E = 0.00 V

On the...

SinceECu2+/CuECu2+/Cuhas a greater positive value thanEH+/HEH+/H, the reaction that is feasible at the cathode is

Cu2+(aq)+2eCu(s)
