Thermit reactions :-
Sometimes reactive metals like Na, Ca, Al etc. are used as reducing agents to obtain metals from their oxides. Eg :-
3MnO2 + 4Al ----------> Mn + 3Al2O3 + Heat
The reaction between metal oxides and aluminium is highly exothermic and the metals are obtained in molten state. Such reactions are called thermit reactions. The reaction between iron oxide and aluminium produces molten iron. This reaction is used to join rail tracks, broken machine parts etc.
Fe2O3 + 2Al ----------> Al2O3 + 2Fe + Heat

Answer:
Hey dear
Here's your answer :)
Explanation:
Acid: An acid is a compound which when dissolved in water yields - hydronium ions {H₃O⁺} as the only positively charged ions.
Example : HCl + H₂O → H₃O⁺ + CL⁻.
Bases : A base is a compound which reacts with hydronium ions {H₃O⁺} of an acid - to give salt and water only.
Example : CuO + 2HCl → CuCl₂ + H₂O
Salts : A salt is a compound formed by partial or complete replacement
- of a replaceable hydronium ion of an acid
- metallic ion or an ammonium ion.
NaOH + H₂SO₄ → NaHSO₄ + H₂O →→→→→→→→→→ Partial replacement
Hope my answer helps!!!
