WebThe reaction is: iron (III) oxide + aluminium → aluminium oxide + iron. This shows that aluminium is above iron in the reactivity series. Once underway, the reaction is highly exothermic, rapidly reaching temperatures as high as 2000 °C, well in excess of the melting point of iron (1535 °C). The practical use of this reaction is to weld ... michael brown altered spaceWeb, for an exothermic reaction will always be negative. In the presence of water, a strong acid will dissociate quickly and release heat, so it is an exothermic reaction. Exothermic reactionIn an exothermic reaction, the total energy of the products is less than the total energy of the reactants. Therefore, the change in enthalpy is negative, and ... michael brown 2014Web3. Draw an or find an image of an endothermic reaction or an exothermic reaction.
