A beaker contained 75.0 #cm^3# of aqueous copper(II)sulphate at #23.70^C.# when scrap iron metal was added to the solution, the temperature rose to #29.3^0C#.
a) Write an ionic equation for the reaction that took place.
b) Given that the mass of copper deposited was 5.83g, calculate the molar enthalpy change in kJmol-1.(specific heat capacity of solution=#4.2Jg^-1K^-1#,density of solution=#1.0gcm^-3#,Cu=63.5)
