1 When 25 cm of 1.0 mol/dmº copper sulfate solution was mixed vith an excess of zinc powder, the temperature of the solution rose by 50.6 °C. Calculate the energy change
for the reaction in kJ/mol.

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
