Answer:
Explanation:
The equation for this reaction is: 2 Al(s) + Fe 2O 3(s) --> 2Fe (s) + Al 2O 3 (s). The large decrease in the energy of the system is a consequence of the high charge concentration on the aluminum ion due to its small size.A thermite reaction (a type of aluminothermic reaction) is one in which aluminium metal is oxidized by an oxide of another metal, most commonly iron oxide. Although the reactants are stable at room temperature, when they are exposed to sufficient heat to ignite, they burn with an extremely intense exothermic reaction.
MgS + N2 --------------> 2Mg3N2. Explanation: In the atmosphere, the magnesium ribbon is burnt in the nitrogen gas in order to form magnesium nitride which is in the solid state. On balancing the equation, three moles of Magnesium ribbon is treated with one mole of nitrogen to form the balanced magnesium nitride.
