To get the exact measurement
Answer:Oxygen
Explanation:
Oxygen gets reduced when iron is oxidized.
Endothermic reactions are reactions that require heat in the course of the process. The heat of reaction in this case is positive which means the energy of the products is greater than the energy of the reactants. In this case, the answer to this problem would have to be <span>1. must be greater than the required ΔH </span>
Hemoglobin
The protein inside (a) red blood cells that carries oxygen to cells and carbon dioxide to the lungs is (b) hemoglobin
Anode- oxidization
Cathode-reduction
