Answer 2

Answer: True

Rusting of iron is an irreversible change.

Explanation:

• Any change which can be reversed or are temporary are called as reversible changes.Chemical reaction which can be reversed are called as reversible reaction.In such reactions no new substance is formed. Example- boiling, melting , freezing , melting of wax are reversible changes.
• Reversible reaction can be shown by following equation -

                       A + B ⇄ C + D

• Here A and B are two reactants which reacted to form C and D. The two headed arrow indicates that the reaction is reversible and A and B can be obtain back from C and D.
• Any change which can not be reversed or are permanent are called as irreversible changes. Chemical reaction which cannot be reversed are called as irreversible reaction.In such reactions new substance is formed. Example - heating , burning , mixing are irreversible changes.
• Irreversible reaction can be shown by following equation -
•                        A + B →C + D
• Here A and B are two reactants which reacted to form C and D. The single headed arrow indicates that the reaction is irreversible and A and B cannot be obtain back from C and D.Hence new susbstance is formed.
