Which of the following is an example of chemical reaction? Options: A . &nbspConversion of steam to water B . &nbspRusting of iron C . &nbspCutting of wood D . &nbspMelting of ice candy

Answer: Option B : B Rusting of iron is a chemical reaction. Whenironrusts, it reacts with oxygen present in water or moisture in the air to create a new compound callediron (III) oxide. F e ( s ) + O 2 ( g ) → F e 2 O 3 . x H 2 O ( s ) F e 2 O 3 . x H 2 O is commonly known asrust and has properties entirely different from that of iron or oxygen. Other options involve either change in physical state or size.

B . Rusting of iron

C . Cutting of wood

D . Melting of ice candy

Answer: Option B
:
B
Rusting of iron is a chemical reaction. Whenironrusts, it reacts with oxygen present in water or moisture in the air to create a new compound callediron (III) oxide.

F e (s) + O_{2} (g) \to F e_{2} O_{3} . x H_{2} O (s)

F e_{2} O_{3} . x H_{2} O

is commonly known asrust and has properties entirely different from that of iron or oxygen.
Other options involve either change in physical state or size.
