Carbon-12 and Carbon-14 are isotopes of Carbon. Although they have the same number of protons, the <span>number of neutrons in each atom is not the same~</span>
Democritus said that the atom was just a sphere.
The simplest ion that copper forms in solution is the typical blue hexaaquacopper(II) ion - [Cu(H2O)6]<span>2+</span>
The answer to your question is dependent variable.
You can use the equation ΔS(surr)=q(surr)/T or ΔS(surr)=-q(rxn)/T.
the two equations are equal since we know that the energy the system (reactoin) puts out just goes into the surroundings.
(In other words q(surr)=-q(rxn))
Using the equation, <span>ΔS(surr)=-(-283kJ/298K)=0.9497kJ/K or 949.7J/K
This answer makes sense since the reaction is exothermic which means it released energy into the system which usually causes the entropy to increase.
I hope that helps.</span>
