Question

Identify the type of chemical reaction in the following statements and define each of them : (i) Digestion of food in our body (ii) Rusting of iron (iii) Heating of manganese dioxide with aluminium powder (iv) Blue colour of copper sulphate solution disappears when iron filings are added to it (v) Dilute hydrochloric acid is added to sodium hydroxide solution to form sodium chloride and water guys I have exam tomorrow

Answer 1

1) Digestion of food-- oxidation reaction
2) rusting of iron--- oxidation reaction[corrosion]
3) manganese dioxide and aluminimun powder:

3MnO2 + 4Al ----> 3Mn + 2Al2O3

Aluminium powder is a reducing agent. These displacement reactions are so exothermic that the metals are produced in the molten state
4) Cuso4+Fe---->Feso4 + cu
Displacement reaction
5)HCl+NaoH--> Nacl +H20
Neutralization reaction.

Answer 2

here is your correct answer
