An iron atom has a charge of zero. It's charge increases to 2+. Due to the increase in oxidation state, the atom is said to be oxidised. Oxidation occurs when an atom loses electrons.
Hence, the answer is (a).
The amount of energy that was used to heat Cu is 27.6 cal
<u><em>calculation</em></u>
Heat (Q) = M ( mass) x c(specific heat capacity) x ΔT( change in temperature)
where;
Q=?
M = 5.0 g
C=0.092 cal/g°C
ΔT = 80°c-20°c=60°C
Q is therefore = 5.0 g x 0.092 cal / g°c x 60°c =27.6 cal
