Energy given by carbohydrates present in one cup =
= 128 kcal

Answer:
Iron metal is more reactive than copper.
Explanation:
Iron metal is more reactive than copper. ... Cu is less reactive than iron, therefore, cannot replace iron from iron sulphate (FeSO4). we have already seen that iron is more reactive than copper. So that means that in this reaction, copper is less reactive than iron. That means copper cannot displace iron. It cannot kick out iron from a sulfate.
